I can't figure out the Hot Start Option on my Nautilus. Manual claims that it "heats the wash water". But it drains just prior to the main wash. And since the first fill/drain is so short the detergent can't do much in that wash. So how does the Hot Start function?

Good Question

I would assume that it would heat the water to warm up the interior of the machine.  You may want to pull the kick plate and see if the technical instructions are there.  They should explain the operation of your model.

Malcolm, Interesting idea. With the tank hot and dishes hot there would be less mass to heat up to temp.

Blowing Out the Lines

It allows water entering the machine to release any cold standing in the supply and be sure hot water is available for the first wash.

My experience...HOT start

stainfighter's profile picture
While we couldn't stand the noise our Nautilus really took anything you could load into it. Our example would heat up the calrod for about 7 minutes before introducing hot water into the chamber, it really made for an incredibly HOT pre-wash! We swapped it out several years ago for a Whirlpool TT

Mixfinder, mine doesn't seem to do that. The first fill is a wash with no purge and is very short so the whole batch of detergent is lost, the rest of the "hot start" cycle is rinses until the regular "start" which begins the main wash.

Stainfighter, mine has the annoying pause between inital motor start and water inlet but the calrod doesn't heat and yes, it is god awful noisy.

maybe your dishwasher is ment to be use with cascade detergent tablets i have a kenmore dishwasher and me thats what i use as the first wash is more like a rinse or the dishwasher is sensing the load before the main wash?

Pierre, the Nautilus is pretty much low to mid end. Mine is the 2200 with the pots/pan cycle which is interesting because the next one up has exactly the same wash times and water use but has "heavy wash" instead of pots/pans. The manual says p/p will clean baked on crud, but h/w won't. Anyway these little gems don't have sensors.

Hot Purge

mrb627's profile picture
I wonder why manufactures want the operator to purge the hot water line before starting the machine. Why not just build that into the beginning of the cycle?

Agree about line purging. Almost all DW manuals and detergent instructions say to "let the water at the tap run hot before starting the machine".

I could see doing that in the day when cycle times were much shorter and many machines did not have heaters. On modern machines the cycle times are so long, even if one purges the line before starting, the water in the lines gets cool before the next fill.

If they built a purge into the beginning of the cycle, it would affect their EnergyStar rating...God forbid they let that happen.

not with my dishwasher and my dishwasher is a kenmore elite

well with my dishwasher and me using the smart wash cycle it is not needed as it heats the water as it sense the load of dirty dishes inside and i also have the high temp option always active as well.

I have been 'hot starting' dishwashers since 1981. When I figured out that it took half a fill for the hot water to actually reach the DW. So I run the faucet until hot THEN start DW.

Doing that for every fill, even at my laid-back tank temp of 115F, the DW works great. If your heater temp is the DW-recommended 140F and half of it is slab temp (70F, summer), that's only 105F tub temp.

Truly functional 'hot start' should run fill water down the drain until it reached at least 105F. I mean, what else is all this Star Trek sensor/computer nonsense good for?

The hot start feature has nothing to do with purging the wat

appliguy's profile picture

According to the owners manual for my 2009 GE Dishwasher, the hot start option is used when you have heavily soiled or dried on/baked on soils. It says it adds 20 minutes to the wash cycle when selected.  I have used this feature many times and from what I have observed all it does is turn on the heating element during the  pre rinses of the cycle you have chossen and heats the water to enhance the pre rinsing ability of the dishwasher. When I have used the hot start feature in conjunction with putting extra detergent in the second detergent compartment of the dishwasher and using the hot wash option as well it has given me great results even with baked on/ dried on food....PAT COFFEY

maybe but it also depends on the dishwasher some may need to have the water running from the faucet first but not the dishwasher i have as soon as the cycle start as my dishwasher fills its starts heating the water as it sense the load while filling and in the end i get clean dishes.

Pat, I think you cracked the code! Found this on the Appliance Web as well:

Posted by sparky823 (My Page) on Wed, Jan 16, 08 at 0:44

The Hot Start is where the heating element comes on in the first fill to heat the water to get the dishes "warmed" before the main wash--at least this is what GE told me back when I was looking and I asked about this feature. I am not sure but I think it is designed to heat to 95degrees for Hot Start because you know that most first fills are cold water if you don't run the sink first. Even then you have the cold tub,dishes,and leftover water in sump from previous run.
About the wattage: My water heating watts are 840. When I was talking to GE before I also asked then about wattage and the model I asked about listed the "Calrod" as they call it, as being 1200 watts. When I asked the lady about this she said "I can't believe this is correct". "It is an Energy Star machine and I don't believe that this is right", but then she never found anything else on that model that said different. Although on another model I checked the wattage was 825 for water heating and 665 for dry because it too had a "multi-watt" element. My old GE just had a straight 500 watt element.

I thought you got your fuel/RPM mixture wrong and when you started your jet engine, a wall of flames about 25 feet long came out the back of the engine. Now THAT'S a Hot Start!

Hot Start

mark_wpduet's profile picture
I saw this on a friend's GE dishwasher just the other day and I wondered what it meant. That sounds like a GREAT idea! Get it hot at the beginning and it stays hot throughout. They should all do this, especially if you set your delay start since there will be no one to purge the cold water.

me it is not needed since at the end of the cycle i can just press the cancel button and the machine purges the excess water.

Purge

Early model GE impeller machines would run water and pump it out at the same time to purge and warm the sump.

older kenmore dishwasher

pierreandreply4's profile picture
and i also remember that older kenmore dishwashers the first wash also known as prewash would start warm and when the main wash would start the light would switch from warm to hot this model to be precise and credit to turqoise dude for the pic and if the sani wash option was chosen the sani light and delay light would light up as well.

Please view this video: (54 seconds)

If after viewing that video don't you wonder why in the world they would put such a button on an appliance. I mean, hot starts are not something you strive for!

Good to know.

I randonly assumed the HOT start on a GE was a fill, a two or three minute wash, then a pause with no wash action to heat the water until it reached the desired temp. HOT start; no noise.

I then assumed the machine started washing once the water was hot.
Put a quick rinse in there to re-heat the water in the lines and then a main wash!

For me, I'd get a 2 gallon (say 8 litre) electric hot-water heater under the sink for the DW and avoid all such problems.

Pierre, I believe it is time I realign some of your misconceptions about your dishwaher.  first, read the user manual.  It specifically states you are to run the tap at the kitchen sink before you turn on the machine.  Secondly, the heating element, MAY  be energized during prewash, but it doesn't heat the water but 3 to 5 degrees F during the prewash.  There is no thermostatic hold to raise the temperature.  The main wash will heat the water to a certain temperature, but atht depends upon options selected when you use smart wash.  and incidentally, when you use either high-temp or sani-rinse with the smart wash programme, you cmopletely negate all intelligence of the cycle.  the programme defaults to a speficied program sequence without any variance.  the final rinse water is also thermostatically held/heated to a set point.  I let  SmartWash do what it was designed to do, let it select all variables to clean the load, be it water changes, water temperaturs and cycle length.  The ONLY US. designed dshwasher that had a temperature delay hold for a pre-wash was the Whirlpool PowerClean and Kenmore UltraWash dishwashers when the Pots/Pans, PowerScour cycle was used. 

 

Now as far as your comment about the older D&M Kenmores with the water temperature sequenced lights, the machine started out with "cool" light being lit.  there were a total of 3 water changes prior to the main wash.  And if the household water heater was set at 140 or 150 degrees, then by the 3 water change, the light had changed form "cool" to "normal".  that is where it stayed unless you used the sani-Rinse option or Sani-Wash cycle.  Then, it delayed the timer advance on the final rine until 155 degrees was met.  the nomral and delay light would be lit until the 155 temp reached and then the sani light would light up.

Kenmore Dishwasher!

peteski50's profile picture
Pierre I have a friend that had the same exact dishwasher builtin. It was a great machine. The only delay hold was if you selected sani temp and occured in the final rinse. The wash portion had the heater going but it only helped maintain the temperature. Their was no other delay - the cool and normal temp lights only indicated if you house hold temperature was to low. Theirs was always good because their temp was set at 140. The cycle always regeristered hot and than if sani temp was selected the sani light would come on in the final rinse.

I think the hot start feature is a good idea. I do purge the lines if I am sending the dishwasher through with a lot of dishes or if the load is very dirty.

But whilst on the topic of hot start, there is a portable on kijiji here in Dartmouth with a hot start feature.

Hot Start....

gmmcnair's profile picture

My GE portable has the Hot Start Feature....it basically adds a couple of extra fills to the mix so everything is steaming hot when the main cycle hits. I think they rebadged it as Hot Start to keep their Energy Star status.

 

No heating element comes on during mine...I don't have any kind of water heating options. I like it...it adds only 10 minutes to the cycle time, and I get very clean dishes....no little food specks on anything in 2+ months of daily use.

Seems to me, the "Hot Start" option should be called "Cold Start" since it basically means you are starting from a cold machine or purging the cold water from the water line. At least it puts the water to good use and rinses the dishes with it.

Interesting that the portable that Maytag posted HS timer segment is so short on the dial as compared to mine. I suspect that has to do with getting the Energy Star rating which mine doesn't have.
