CountryBoy posted recently that he purchased a new TT Kitchenaid DW and he is satisfied with the results. My question is this.. If you check the user forum at K/A's Website, there seems to be an overwhelming amount of people who complain that the dishwasher leaves residue on the dishware especially in the upper rack.
The standard response seems to always be to use the Vinegar wash and everything will be fine. With all things being equal, i.e the Whirlpool and Kenmore and KA machines being the same units, why would the K/A seem to have the problem more so than the other Brands?
Is there something radically different in the K/A machines that set them apart?
I don't want to believe it is the washarm since they all have 10 nozzles. The current Hydrosweep 4 way arm seems to have smaller jets than the previous designs and it seems like it doesn't extend out as far as the older ones.
I have a Whirlpool DU950PWKQ1 as an overflow machine in the garage and it seems to clean really well, but it is not a TT and it has the vertical pump assy. I have to assume that the horizontal pumps arent as powerful as the older style units?

Does anyone have any input on this?

I have a brand new KUDP02IRWH2 still sealed in the box. Should I replace my KDS-18 and lie with the superlong cycles (though I have my hot water heater set above 150) or just wait till the tank retires? Then I have to wear out my KDC21D machine!

BTW..IF anyone would really like to purchase that unit..I will consider selling it in a heartbeat and avoid the problem altogether!

Good Evening,
If you have a KDS-18, in great working condition.....I would not replace it for anything right now.
You have a real Hobart Design dishwasher. The pump that really used the Hydro-Sweep.
I have a KDS-18 in my kitchen that I have been using for about 1 year. It was actually new and never used when I bought it. I also have a KDS-20 Portable that I use just as much. I would not trade them for anything.
When these go (and I think it will be ages), I have back -up dishwasher's that were made by Hobart, just in case I need them.
I have used several of the tall tub designs. I think they are great if you load them correct. I just can't stand the 2 hour wash cycles. I don't get where the energy is being saved with the current design dishwasher.
My 2-cents worth.....
Brent

Nothing works like the hobart KitchenAid's
My mother had one for 25 years.
I wish they stayed with Hobart and I wish they would have made a tall tub design.

Stevet,

Your reference to 'countryboy' I am assuming was in reference to me 'countryguy' :-) No longer a boy, all grown up now! LOL

Anyway, I did indeed purchase a new tall tub Kitchenaid and so far I am very pleased with it. I have done several heavily soiled loads with racks full both in the top and bottom and everything has come out spotless. I even put the roast pan in last night, used the normal cycle with proscrub turned on and it came out clean. The cycle was about 2 hours including dry time.

I have a Kitchen aid that I purchased 3 years ago, and it is by far the worst dishwasher I have ever owned, due to the exact reasons as the many posts show on the website mentioned here. I have done virtually everything in the way of what all the experts say to improve the cleanliness of the dishes, but no matter what I do, ultimately the dishes have crud, left over food etc. Even the inside door panel still has stuck on food after a full wash. Silverware is always dirty. I have been told by some people who emailed me from Kitchen aid that there have been problems with their new pulse and wash systems, which supposedly use much less water than other brands. The machine stops to allow water to go to the bottom, then starts with 'bursts' of water, rather than having a constant full water flow. I am very dissapointed, as the machine seemed to be built very sturdily, which is one of the reasons I purchased it at such a high price. After having several other brands of dishwashers without ever having these sort of problems, at this point I would never recommend Kitchen Aid to anyone due to the horrible results I get in poor washing. I have even had service twice on the unit, the service men say the same thing as I have posted here as well, nothing you can do about it, it is the 'new' design that they have been having poor results in washability. Kitchen Aid themselves do not seem to want to address the issue, and you get no where with them when you try to complain to their customer service, they don't want to hear it. All they keep doing is sending me a basic document that they created with 'suggestions' for better washing results, such as water temperature, soft water, loading, detergent etc. All of which are fine in my home. Even if I have a 'half' load in this machine, it does not come clean on a regular cycle. This is my experience, but I have been in contact with many other consumers through the website who have had the same terrible experience with this product.

If you want to go with a tall tub dishwasher, a Maytag or JennAir has had a better track record for cleaning. They have a bigger pump and motor. If the sensor decides that the water is so dirty that another water change is necessary, the machine drains completely and refills, unlike the KA machines which use a different method to determine turbidity in the wash water and then only purge a small part of the water and replace it with an equal amount of fresh water. The whole trouble is that these new machines are trying to use too little water to thoroughly clean dishes. At least in the KA style machines, the sump is too shallow to hold enough water for the pump to maintain full water pressure during circulation. That is why they have tried the pulse process which shuts off the motor and allows the sump to fully fill with water and then starts the motor to throw a strong surge of water against the soiled pieces in the load. The other reason for poorly cleaned dishes with residue on them is that the machine only gives one rinse after the wash on all but the heaviest soil settings. The machine uses a very small amount of water and that small amount combined with the poor water circulation does not rinse dishes well. A bit of history on this topic. In the very early 50s, 1950s, for the very young, Consumer Reports did a test of dishwashers. Among the brands they tested was an APEX machine with a timer dial on the backsplash of the machine. The cycle in that machine was one wash and one rinse. It did not perform very well with that cycle, but Consumer Reports generously stated that if the machine was set to give another rinse, the results were far better. I found that very true in the 21 and 22 series electronic Superbas that I had. The cycle only gave one rinse after the wash, but if I added an extra rinse, things came out much better. The Maytag and JennAir machines have options that, when chosen, provide an extra rinse after the wash. Two rinses are better than one.

Tall Tub

I have the GE tall tub and like the machine. It gives 3 rinses in the normal cycle. I am pleased with that. I don't care how much water is being used. Any dishwasher should give at least 2 rinses. It is just ashame what happened to KitchenAid.

I've got a GE Tall Tub, too...the 9800 I believe with stainless interior. 45 - 47 minute Normal cycle...and it cleans brilliantly...no residue left on anything, anywhere. Easy to load (though I am not too crazy about the short tines on the lower rack...pain in the butt with certain dishes).

Over the weekend, I sold my KitchenAid KUDS23 Superba dishwasher, only because the GE just holds more and fits my big pots and 12" dinnerware, where the KA is too limited. It killed me to do it, but I don't have room for two. (It went to a very good home where it will be loved and appreciated!) But the GE washes just as well, if not better than that old KA did. The multiple rinses do the trick. The Normal cycle in the GE is a Wash-Wash-Rinse-Rinse-Rinse sequence, using 7 or 8 gallons of water. If it senses the dishes are clean after the second rinse, it just drains and shuts off. Works every time. Convection drying with no heat leaves everything dry as a bone, except some plastics.

I think the real issue may be why some of the KA units have this problem, and others do not....there are plenty of satisfied KA customers out there with these machines...we have some here. And why doesn't it seem to afflict Whirlpool/Kenmore Elite machines? THere is a bug somewhere, and KA isn't owning up to it, or just can't figure out what to do about it.

Hi Marc,
That sucks about your dishwasher. Did you have any kind of plan that if you were not happy, they would take it back? It really is a sad situation when you pay so much for a "Name" that was trusted for over 50 years, that you end up with a machine that is like this. I would push it with them. It is only if the consumers that are willing to push this issue, that they make the changes that need be!
Tom, I totally agree with you about the washing "pressure" and the lack of extra rinses. It makes all the difference. I think that "Kitchenaid", if you can even use this name without gettting pissed, was all for getting that "energy saver" logo on the machine. This is what buyers are looking for now. In the home that I moved into, it had the Maytag three rack design. I have to say that the pump, and the water it used was very well designed. It just took too long for me.
Gary, I think it is great that your Kitchenaid is working out for you! That is super. It would be great to get all of these machines together, and test them. I would bet that something is a little different about each of them....
The reason I say this is Andrews point about the Whirlpool / Kenmore Elite machines not having this problem. I find it it all so interesting, and I would bet that they use more water, and have the extra rinses.
Bottom Line in my own thoughts....I think that the machines that are cleaning well, are using more water.
It is very easy for the "brands" to test all of these machines on the consumer, at the consumers cost. This is why I say fight, and get them to give you something that cleans! It does not cost them anything in the long run, and they develop a better machine!
I truly think it is all about getting that "Energy Star".
My 2 - cents worth!
Brent

Imagine. What a concept!

I bet Uncle Sam never figured some of use would COVET machines that are water-hogs. So much for the INTENDED purpose of those yellow gov't energy-saver labels (White in Canada).

People want "Energy Star" but fail to do the math in terms of matching performace with energy savings, if any. If dishes have to go through an extra cycle, laundry washed twice or some such, where is the savings in that?

There is no getting around the fact that to wash dishes and laundry one needs a certian amount of water. You don't hear about "Energy Star" commercial units, or if they do exist not causing the amount of problems domestic consumers seem to have. Why? Because commercial units have to perform for if nothing else for the sake of public health.

Being as all this may, our 18" Kenmore (built by Frigidaire) portable does a decent enough job with two washes and one rinse for the normal cycle. Used to reset the dial for a second rinse, but found it made no difference in terms of cleaning results, nor was the wash water any cleaner after the second rinse. Our machine does purge/rinse the sump/drain/filter between the pre-wash and main wash,then again before the rinse.

Interestingly enough, in checking out the newest KA dishwashers online, when you select the Hi Temp Wash option, the machine automatically adds a second rinse, in addition to heating the water in the first wash on the Heavy cycle, and heating water to 140 on the normal cycle. Don't know if previous versions did the same thing or not, but maybe they've gotten wise to the issue? I also noticed that the "normal" wash temperature is down to only 120 degrees, depending on what the sensor decides. If you want 140 guaranteed, you must use Hi Temp Wash.

Now, I ask you, does anyone think the average dishwasher consumer really understands what this all means to the cleaning ability of their new high priced dishwasher??? Would you really want your soiled dishware and utensils washed at only 120 degrees? Actually, the range they give is 105 - 140 degrees, depending on what the sensors decide.

It seems they took the real "Normal" cycle and dumbed it down, then optioned it up with the "HI TEMP" option. Saves energy, but does it clean? If I were KA, I think I'd be more concerned about the machine's cleaning ability, and thus, the company's reputation rather than trying to save 2 friggin quarts of water.

You know, the wash time in my 1989 Superba was all of 14 minutes on the normal cycle - W-R-W-R sequence with one purge, and it cleaned very well....at 140 degrees with 2.5 gallon fills. Go figure.

Far as I understand, EnergyStar ratings are based on the Normal cycle with default options, for both washers & dishwashers. Configuring a very low-resource "normal" cycle then providing options to beef-up the performance is likely an easy way to get EnergyStar qualification, but consumers likely aren't aware of it. The typical user doesn't read the instruction manual, isn't aware of the options and what they do.

To be fair, when one chooses "Normal" wash cycle for dishes or laundry, don't want to bother having to go through hoops to get good results. This is one reason am simply not interested in the cheap tat they sell as appliances nowadays. Will keep my vintage stuff working for long as possible even if one has to tramp up and down Europe for parts.

Am seriously considering latching onto a vintage Hobart/KA dishwasher, but it would have to be portable and not sure if the full 24" model would fit.

I did a stuffed BobLoad in the elite tonght, Smart Wash. It did a full 1st rinse rather than purge and heated main wash water to 140. I did a load yesterdy afternoon that was pretty "clean" for me. It sensed harly any soil and went from pre-wash to main wash without drainig. The main wash was 20 minutes long, water at 115 or 120, which was fine with me since it was a 'clean" load basically--had done a rinse&hold the night before. I don't hit the sani-rinse option until it begins filling for the final rinse. The "clean load" finished in 104 minutes with the sani-heat and the 30 minutes for heated dry.

Nice to read all the information here posted by all of you. As for what Brent suggested about contacting Kitchen Aid about the issues I have with the machine, I did everything possible to try and be a squeaky wheel about it, including writing to the heads of the company, but it did no good. All I got as a mailed response was a pre printed suggestion sheet about how to load dishes, and a check list about water temp, hardness etc. Customer service didn't even want to deal with me, and only suggested I have a repairman come out. They seemed totally disinterested in the fact they had an unhappy customer, couldn't care less, which was dissapointing to me. I could not return the machine as I bought it from a private appliance store. I originally WAS considering the GE Profile as mentioned in this thread, and now have 2 relatives who have them and get perfect results with short wash time. If I choose the high temp wash or sani rinse, my machine runs almost 2 hours, such a waste of energy, and even then, there is still soil on some dishes, and the inside of the door still hold food residue! My old dishwasher used to get the whole thing done in less than an hour on normal cycle, and perfectly clean, even baked on stuff (it was a Maytag Jetclean). I really thought Kitchen Aid was going to be a workhorse of a machine, expecially with the way it looked to be designed so nicely, but in my case, it did not turn out that way. I do believe that all of you are correct, companies may have 'differences' in models or manufacturing that would cause 'some' of the customers to have such bad experiences, but truly I have never had such a poor experience, or poor response from a customer service department. It is sad that Whirlpool now ate up Maytag, if this is any indication of their customer service, it does not say much for the company.

I don't think anyone's customer service experiences mentioned here should be considered to be atypical of any manufacturer these days. Squeaky wheel or not, manufacturers know that your choices are limited, very limited, so they lose a few here, gain some more there. It's just a numbers game for them.

The thing I still don't understand, though, is how GE does it in a relatively short Normal wash cycle, and does it very well, and others take upwards of 2 hours to do the same job? Does GE do something magical inside that box that we don't know about? The Normal cycle has never taken more than 60 minutes, and has run as short as 30 minutes or so, depending on soil level, but usually averages 45 - 47 minutes. I don't use the dry cycle. But it always does a separate pre-wash, no matter the soil level; it just cuts rinses for cleaner loads. Something just doesn't seem kosher here. It's energy star rated, just like the KA/Whirly/Kenmore Elite, though it does have a much larger heating element - 1000 Watts. Maybe that's a difference? It does heat very quickly.

That Hi Temp Wash option is a direct transplant from Maytag and well overdue. I am glad to hear about it.

Actually the new WP Tall Tubs have had their cleaning troubles as well. I guess not as many people here use them.

As I stated before, the bean counters at the energy department ran the machines with clean dishes to test them for the energy star rating. Hmm... Gets 'em wet; give it an energy star.

When WP/KA introduced the tall tubs, they were energy star rated but the standard tub WP machine was not. I said at the time that it would be the one that really washed dishes.

How much water do the new KA machines use?

I've got a Miele that can do a full R-W-R-R cycle with 13 -19 litres (3-4 gals) of water on a sensor wash. Do the KA machines use even less than that?

And yes, GE fairies are horribly frightful little creatures. Maybe that's what's wrong with the newer KitchenAids?? GE fairies have possessed them!! Everyone, check for fairy dust inside your KitchenAids!!

Very interesting...my parents have a TT Kenmore (with sensor) which doesn't seem to work very well IMHO but I've got a roughly 3 year-old non-TT Whirlpool (also with sensor) which works GREAT... I rinse much less than they do and the only things which need a go-back are wooden spoons and utensils (I'm not absolutely convinced that in-the-door is perfect for silverware etc) and a 13" saucier in which I make a frittata (i.e. stuck on eggs) which barely fits and doesn't get too clean. My folks have had bad luck with dishwashers...I remember a James back in the 1967 timeframe which was acquired from my great-grandmother (thought it was so cool that the d/w was named after me...this was just at the time I was learning to read, then a 2 cycle Sears portable which my dad and I converted to permanent installation but left on the cabinet (I could take it apart in nothing flat---we seemed to drop milk caps into it, and there was no filtering--only a macerator...we replaced the motor 1x in 10 years), then moved to a house with a built in Youngstown 30" (what a POS...we replaced it within the 1st month we were there...the house was built in 1957 with a full Youngstown kitchen which had been veneered with Formica...still had original Tappan/Youngstown 36" cooktop). My dad and I replaced with a Kitchenaid Imperial(this was the 1st year of the 3 level wash...also a POS which lasted <10 years). We had to order the side panel separately. They redid the kitchen in 1987 and put in the GE 1200 (I think--mechanical, but with the good upper rack and filtering system).

sounds like WP Corp. needs a lawsuit against them for the KA brand.
What's taking so long?
If KA wants to use such little water. Then what they need to do is split up the spray feed. They'll need to run the lower and upper spray arms separately just like Frigidaire.
Our apartment's Frigidaire uses just 1 gallon per fill, and alternates the spray arms. It does wash quite well.
It's no potscrubber, but it works.

We too have a GE tall tub from 2003 and it is great.
I'm not sure how they're able to do it, but the lightest sensed Normal wash in our GE Triton XL is a W-R-R-R and uses just 5 gallons of water and takes 47 minutes, sans the heat dry.
I think that's pretty damn good.

KitchenAid / GE

peteski50's profile picture
I have the GE tall tub also. On normal it will do w r r r but if it has heavier soil it will do 1 or 2 prewashes first. I can also use the prewash option if I choose and even if the sensor says it doesn't need a prewash 2 are given with the prewash option. I usually just use added heat option if the dishes are very dirty. That gives a sani rinse.
As for KitchenAid it is sad it is not still made by hobart
What happened to them is almost as bad but not quite as bad as what WCI did to Frigidaire.

Has anyone had any experience with the newest KA dishwashers that just came out? New racking system on the bottom on the top line machines, and, interestingly enough, when I demoed one in an appliance showroom last week, I opened the door while it was washing, and the water actually shot out the door from the upper spray arm and wet the front of my shirt. Maybe it's a step in the right direction for KitchenAid, but the machine still does the pulsed wash where it stops/starts the motor a series of times.

I think we all feel it here....these iconic brands that we've all known and loved our whole lives being relegated to mediocre, or worse, troublesome performers that cost big bucks.

Well, there is obviously some performance differences between the WP TT cousins if my Elite has passed every BobLoad test I've given it since I got it in May.

Bob - I haven't read that customers are having the same problem with the Kenmore Elite machines like you have, even though it's a similar design. At least not to the extent that they are having problems with the KitchenAid versions of the machine. I hope yours continues to be trouble free for many years!!

So, compared to the old GE 1200, do you like this one better? What do you like better (or worse) about it? Inquiring minds want to know!!!

Well, for me, it's very dishearting to hear such things about a Kitchenaid. I guess like many here, years ago Kitchenaid was the BEST to buy. Now...... Anyway I remember an advertising blitz years ago on TV that showed women trying to load their dishwashers, with their frinds in the kitchen saying "should have bought a KitchenAid". I guess now it should be "should have bought a Bosch". My Bosch uses 4.4 gal on a minimum sensed level(which is what is senses on most loads) which consist of Purge, w,r,r. When I put turly nasty things in and select regular wash it will do Purge, r,r,w,r,r and only uses 7.8 gals. Everything always comes out gleaming and spotless. When this thread started I got to thinking, I want a kitchenaid. Now I'm truly glad I have my Bosch.

I have not had any problems with the new KitchenAid I just bought. Everything so far has come out spotless and believe me I have put in some real dirty dishes, casseroles, etc. - all with no pre-rinsing. And most of the time the dishes sit for a day or 2 unless there is a full load to be washed. Did I just luck out with my Kitchen Aid.

Gary,

My secret hope is that Kitchen Aid has made some improvements to try and combat the poor performance of models like mine that are 3 years old, and pehaps they have secretly paid attention to the many complaints they have received from customers like myself. It would be nice to hear that the newer models such as yours are performing better. I doubt that Kitchen aid themselves would admit to the need to improve their machine, but maybe they have. I do hope you have great luck with yours, I would hate to see anyone stuck with the situation I got buying this machine. One has to wonder what goes throught the minds of executives that make decisions on design that compromise the integrity of the iconic name brand they have? The name recognition obviously has come from past years where they had a product that had great cleaning results and reliability. If they were smart they would never compromise those to requirements or dumb down their product just to fit into energy star. In my opinion, a machine that uses 2 hours of electric to do one load of dishes is not 'energy efficient', regardless of how much water it uses.

Dishwasher Electric Usage

dadoes's profile picture
Electric consumption by the machine's pump motor, solenoids, electronic controls and such may not be as much as one would assume or expect.

I connected my DishDrawer to RJ's Kill-A-Watt a couple days ago, ran a Normal (non-Eco) cycle. I dropped the household water heater to 70°F to insure "cold" water to the dishwasher so it had to fully heat the water. Target temps are 140°F for the main wash, 150°F for the final rinse.

Total usage on the meter was less than 0.6 KWH. It's not 100% accurate because 10 hrs passed from the start of the cycle until I read the meter, and the cycle is 115 mins (or 145 mins if the post-cycle drying blower time is included). However, the machine only pulls 3 watts when "idle" so 0.6 KWH is close enough. Based on the electric rate on my last bill, running the load cost a bit less than 7.4 cents (not including the water well pumping the water out of the ground).

Highest power consumption during water heating was about 650 watts. The pump motor and active electronics without water heating was between 115 and 126 watts. The two lid motors which run for about 10 seconds at start of the cycle and a bit less time at the end pulled 89 watts. The electronics and drying fan motor during the dry phase was a whopping 7 watts.

Of course, these figures have no direct bearing on KitchenAid.

Brinomarc,

I am sorry to hear about the horrible experiences with your KitchenAid. If mine was doing the same I would have sent it back to Sears by now. I am quite impressed with mine so far. I really do like how well it cleans, how quiet it is and how easy it is to load all the different size dishes, glasses, casseroles, etc. in both the top and bottom racks.

Gary

People, there are so many ways of getting satisfaction with corporations today; use them. Write the corporation one letter. State the appliance, the dealer, the trouble and the service. Tell them that the letter is going to the Better Business Bureau, the consumer advocate at your local television, any radio talk show that deals with constipated corporations, Consumer Reports and anywhere and everywhere on the web that you can find a forum for dishwashers. Then do exactly those things. Manufacturers have people who look for comments about their products on line and know immediately when someone drops a s**t bomb about poor performance or poor service.

Forty years ago, a friend told us about a man in Canada who bought a new snowmobile that caught fire and burned the first time he had it out. The dealer refused to do anything. The manufacturer would not do anything. The guy rented a trailer to pull behind his vehicle. He mounted the burned up snowmobile on it along with signs that told the brand, the dealer and what happened. He did not have to drive the POS around for two full days before they were at his door with a new snowmobile. Corporations sometimes think that they do not have to listen to individuals so individuals have to go to sometimes extreme steps to let the high and mighty know that there is a problem and that you are not happy with the response their people are giving you. It is no time to be discreet. Get a theater major to advise you, if necessary, but don't take any crap from someone you bought an appliance from. I wish all of you much success in correcting any wrong that has been done to you. Tom

Ran a Normal Eco cycle this afternoon, and watched the Kill-A-Watt meter a little more closely. Main wash and final rinse both heat to 125°F.

Fill (motor runs to check water level), 45 watts.

Motor recirculate during prewash with no water heating, 75 to 106 watts.

Motor drain with water load, 45 watts.

Motor drain with no water load, 30 to 35 watts.

Motor recirculate during final rinse with water heating, 614 to 641 watts.

Drying blower, 7 watts.

Cycle time ~88 mins of which ~22 mins is the drying phase. Four water changes (W-W-R-R).

Total energy use, 0.4 KWH.

WOW! Never thought this would be such a popular thread!

I am heartened to see the response to my post about how well I might expect my Unopened KUDP02IRWH2 dishwasher might work.
I don't want to get rid of the KDS18 we now use but would like something a bit quieter even though I have the old one double wrapped in insulation.
Specifally, though, a few of you mention that you currently have the WP clones but if you would just chime back in and let me know what model numbers you have that would be a help.

To Andrew in Orlando, what model was it you demonstrated and got soaked with? The last thing I would install is a machine that pulse washes the dishes.If that is what they designed it to do it would say there just isn't enough water in the sump to supply constatnt water pressure and that they are depending on that initial burst of pressure you get when you first turn on any pump and then it levels out.
Hoving worked for Hobart for many years, that is what happens when a dishwasher has to little water in it, especially the undercounter units on which the Venerable KitchenAids were all based!

Stevet, the tall-tub dishwashers from Whirlpool for several years now, have the intermittant pause and start scattered throughout the main wash cycle. There is also a brief pulse during the 1st fill to temperature condition the tub & dishes.

These intermittant starts and stops are now part of the filtration and soil sensing process. The water level in a properly leveled & installed machine will be just touching the heating element. This is plenty to provide proper spray pressure through all 5 wash levels.

Why not install you KUDP02 and try it? It will run longer than your porcelain tub machine, but it uses about 1/3 of the water & 1/2 the electricity.

Heavy non-Eco cycle. 132 mins (including dry time), 7 water changes (~5.6 gals), 150°F main wash, 163°F final rinse.

0.68 KWH power used. At the last billed rate of $0.12354/KWH, that's $0.0839 energy cost.

SteveT - The KA I saw was their newest TOL machine. It has a reconfigured lower rack, which looks nice, and holds more than their previous model. I just opened it while it was washing and got sprayed; there seemed to be decent water pressure in there. There were no dishes in it at the time. The machine is certainly quiet, has a better racking setup than the previous generation TOL machines, and has an optional front mounted countdown timer with indicator lights. Nice machine, I thought. The salesman said they haven't sold many yet as they've just came out, but he also said that many people who buy these high end machines don't really care less how well they clean (or not), as long as their quiet and "stylish". He also said that if I didn't want a KitchenAid but wanted a really good dishwasher that he knows I will like and will do a good job for me, to go with one of the JennAir or Maytag TT models with stainless interior. He seemed to think they have a superior wash system, and a better motor (they use the vertically mounted "pancake" style motor, rather than the horizontally mounted motor).

and the answer is???

Andrew,
Do you remember what model series it was that gave you a shower? Was it the "2 or 3" series. I am so reluctant to install my KUDP021RWH
for fear of it not matching the performance of my KDS18. I could care less about energy star ratings on these units as they run so much longer. I cannot see what possible savings there would be.

Steve -

It was a KUDU03STSS, the latest "U" series with the top mounted controls and the display in the front.

Andrew; a salesman saying many people buying high end machines don't really care how well they clean just that they're quiet and stylish.. sounds a little odd to me. To my way of thinking most people paying premiums want it all and they are the first people that are going to be madder than hell if they find out it doesn't live up to its premium price.
Personally I'd deal with another salesman, but then again the vast majority of people selling appliances really don't have actual experience ever seeing the machines they are selling in operation at all.

Pete, I hate to say it, but Andrew is right on the people and their high-end machines. I've had a discussion with a few knowledgeable people here over the years as well as personal observation in many a high-end type environment/home. I can't tell you how many times I've been domestic help and caterers thoroughly wash everything before it's placed in a machihne. Also happens when a bunch of variouis people are helping and the same thing happens.

Sorry Pete, you're wrong on that point. He wasn't a salesman, he owned the place. And his recommendation was either a Maytag TT TOL or the GE Profile TT TOL, not the KitchenAid. But he does sell a lot of KitchenAids and thought that for what I was looking for, I would be happy with the KitchenAid, too, if that's the route I wanted to go. Most people who buy the high end either don't cook or they blatantly pre-rinse or pre-wash everything before it goes in. As he said, it's all for show with his customer base. His is a high end kitchen/appliance showroom with design service.

Anti-Energy Star

I have experience with both the newer KA DW, the one with 3 cycles, Heavy, Normal, and Rinse Only. I always use the High-Temp option for the reasons expressed by many of our members above. Currently am using a Frigidaire Gallery, and unless Pots & Pans (a cycle 2+ hours long!!) is used, the results suck!

Something has to be done about this Energy Star bullshit! Who can we complain to? Are manufacturers all forced to dumb-down their products because it's mandatory to have this asinine, counterproductive certification? Or is it a voluntary marketing gimmick they try to qualify for?

My water bill is about $3 a month, yes, THREE dollars, however my electric bill is another story--thanks to ENERGY-STAR appliances and their overlong cycles!

There are NO savings having to rewash clothes/dishes/what-have-you because the appliance is starved for water!
