Hi,
I'm on to my next problem with this machine. The fill and drain cycles work but the wash cycle is very short and the rinse is non-existent. I hear the wash arm going around at the beginning of the wash cycle but, during the rinse cycle, all the machine does is fill and drain. The wash arm does not spray/rinse the dishes. Is this a malfunctioning timer?

HELP!

I would say that is a timer issue.

Stevet would know for sure

you may have a bad drain silinoid

Bad Drain Valve?

combo52's profile picture
Or possibly something caught in it holding it slightly open, when this happens the water will be pumped down the drain before the valve opens for drain.

This was a fairly common problem on KA DWs when these machines were still around in large numbers.

I just installed a new drain valve, checked the inside of the machine and all the drain hoses so I doubt that's it. If it's a timer issue, can I buy a new timer that will work in a KDI-17A?

Hi, does the machine fill up at all? To check press the Full Cycle button. The machine will first do a short fill (about 30 sec) and then immediately drain (about 60 sec). Then the machine will fill for the first pre-rinse (about 2 min). When you hear the fill valve shut off open the door & check the water level. It should be up almost covering the top portion of the filter screen. If this is not the case then your fill valve is not working right. If the water level is correct, then let the machine continue & listen carefully. As soon as you don't hear the washing action happening when it should open the door & check the water level. If the water level is too low later in the cycle you could have a problem with three things:
1. Your fill valve solenoid is overheating & not working later in the cycle when it's gotten too hot (not very common)
2. Your timer is bad.
3. The water level control is not operating correctly (there is a small pressure switch connected to the sump area by a small rubber tube (front left side of sump). It is designed to stop the flow of water if there is too much in the tub. If the tube connecting the switch to the tub gets clogged it can cause the switch to operate shutting off the fill valve.

The solenoid is easy to check...just touch it (carefully & with the machine off!) If it's super hot that's the problem.

Refer to the service manual you downloaded to see how to disassemble the water level control switch components so you can check the tube (careful this tube can become brittle with age).

If it's a timer I think I have one, which you can have. Keep us posted.

Intermitent Inlet Valve Coils

combo52's profile picture
Were actually a pretty common problem on DWs of this age, best test is to force the DW to fill 5 or 6 times in a row to see if the valve keeps working, if the valve is still orignal it would not be a bad idea to just replace it, they are still available from WP pt# 4170000

New timer or fill valve? HELP!

Okay, here's what's happening:
Soak/Prewash cycle: fills to ~ 1/2" above top of filter, drains, brief wooshing (which I hope is the washer arm
rotating).

Wash cycle: Refill, wooshing for approx 4 min., no drain, water is ~1/2" above top of filter.

Rinse: Drain, no fill, drain again at 3/4 point in Rinse cycle: water level is slightly over top of sump pit.
There is no wooshing at all.

Dry cycle: drain opens and water level drops to bottom of sump.

What's going on here? Remember that I replaced the drain valve. I have a new fill valve which I have not installed but is this a timer problem?

Time for timer???

Does the machine do the same thing regardless of the cycle you selected? Electrically, it uses alll the same sets of contacts throughout the "full" cycles and adds a few extra duties when using the soak cycle. But even so, they way it sounds during your description above, it would indicate a bad timer which is missing making connections at the right time. The machine should never retain the water between a rinse and a wash and vice versa. And the inconsistent or no fills during the rinses don't look good either. Now if it works perfectly in the Normal cycle, then you may have a program switch problem. But I would definitely start looking for a timer and maybe a switch too.

I will skip the Prewash/Soak cycle and just try the wash. That's the way my family always used the machine because we always cleaned the plates pretty thoroughly before putting them in the machine. But someone here told me that you should always run it through all the cycles. Is this correct?

KDI-17A

combo52's profile picture
You should always use the full cycle for full loads, the shorter cycles can be used for small loads of glasses, dusty dishes etc.

Pr-rinsing oils, sugars, and food acids [ orange juice, tomato products and salad dressings containing vinegar ] off the dishes before running the machine can easily cut the life of the DW in half and is not recommended by ANY DW manufacturer.

KDI-17a Timer Sequence

dadoes's profile picture
 
The full sequence of the timer is 60 minutes.  I may not have the duration correct for all of the wash & rinse periods and dry but the sequence of actions is correct per my memory of our KDI-17a.

Prewash/Soak section
Line Purge
- fill for 1 minute
- drain for 1 minute
Prewash 1 2
- fill for 2 minutes (detergent dispenser opens)
- wash for 3 minutes
- drain for 1 minute
PreRinse
- fill for 2 minutes
- rinse for 2 minutes
- drain for 1 minute

Wash section
- fill for 2 minutes (detergent dispenser opens)
- wash for 9 minutes
- drain for 1 minute

Rinse section
Rinse 1
- fill for 2 minutes
- rinse for 2 minutes
- drain for 1 minute
Final Rinse
- fill for 2 minutes
- rinse for 4 minutes
- drain for 1 minute

Dry section
- pause for 5 minutes
- dry for 17 minutes (blower fan runs)
- pause for 1 minute

OFF

1 When Soak cycle is selected, the Prewash changes:
- fill 2 minutes
- wash 1 minute
- pause 13 minutes
- drain 1 minute

2 When Rinse Hold is selected the Prewash changes:
- fill 2 minutes
- rinse 1 minute
- pause 2 minutes
- drain 1 minute
The remainder of the timer sequence the machine does nothing - the timer advances to Off at the "normal" rate, turning every minute.

Next test

Why does pre-washing dishes shorten the life of the dishwasher? Or, do you mean starting it at the Wash cycle shortens the machine's life?

THE NEXT TEST:
I started the machine on wash. It filled, the washer arm turned for about 4 minutes with the water 1/2" above filter. Then I heard the timer ticking away (occasionally making little crunching sounds) for the rest of the cycle with nothing happening until it drained just before the start of the Rinse cycle.

Nothing happened during the Rinse cycle except for the drain valve opening and closing. No filling, no washer arm movement.

Then, on the the dry cycle. The heater and blower work during these cycles.

Pre-Rinsing your dishes is incredibly bad for your dishwasher (as John mentioned) AND your dishes. 

 

The chemicals, all very harsh, alkaline products, are circulating with nothing to "attack," such a food soil. When they can't suspend the food soil, they will begin to attack your dishes, resulting in etching and destruction of nice dinner sets. 

As for the dishwasher, all the parts inside the machine will be "attacked," resulting in the destruction of seals, racks, porcelain and so forth. 

 

So don't do unless you have a vermin problem or some other pressing excuse that isn't just out of habit. The KitchenAid machines are MORE than capable of cleaning the dirty dishes of most people. Some can make too much soil, but you have to be making lots of icky, glue-like foods for that to occur.

KDI-17A DW Timers

combo52's profile picture
You need a new timer, KDC and KDI-17 KA DWs had more than their share of timer problems, lots of burned and loose terminals and contacts, if you find a genuine KA-WP timer they even come with a few new leads to replace the wires going to and from the selector switch that most often burned up. Also before going on a search for a timer I would remove the selector sw and see if it has any loose or burned terminals, if so look for a SS also.

Where to find a timer

Hi,
I looked at the exploded diagram in the KDI-17a manual and found the Main Timer Assembly,
Part #C-115403 but can't find it anywhere on the internet. Does anyone have any idea where I might find one? Is there a nother part number that I could substitute?

When you say I may need a new Selector switch, do you mean a part associated with the push buttons?

Thanks,
T.

Newer part number

The timer number you stated above was changed to 4161395. See if you can find one with that number. Maybe that guy who had all the timers for sale on Ebay a few weeks back still has them. Someone on here should be able to provide the link and you can check with him.

Good Luck
Steve

Here is the link for the timer guy and 4161395 is listed on his site. Send him a note and ask for sure. That's what I did when I needed the new timer for my KDS-15. I got it with no issues and it's working just fine.

The right timer part

I looked on the web and found timers on eBay but didn't see that guy's site. I ordered timer part #4162940 as it looked very much like the one in the exploded diagram. I'm hoping that the wiring is the same. The seller emailed me that it would work. Fingers crossed. Does anyone think differently?

Ralph's link works for me!

I just clicked on the link above and it took me rignt to the site. Unless someone on here has access to whirlpool part numbers to see if the number I gave you has changed to the one you mentioned, I would not take a chance with a different timer. There can be subtle differences between timers if one is for the KDI-17 and the KDI-17A.

SO, make sure of what you are getting or you may get stuck with something you cannot use or modify. Restoration and repair does not mean modification and settling for non-factory performance. Surely you want the machine to work as it was designed.

I ordered the 4161395 timer that you recommended. I hope I can return the other one.

Thanks for all your advice and help. Hopefully, this will be the fix.

The timer I originally ordered

This is the timer that's pictured on the Repair Clinic site. It looked a lot like the one in the manual's exploded diagram. I found one on eBay that matched this part number. Since then, I've bought the part number that you suggested.

This is the link to what Repair Clinic has listed as a timer for a KDI-17a.

Snooping on fellow KDSer

O.K. So i've been following this thread carefully because I just got a KDS 16 and it's up and running right now. But I want to keep it running so I am wondering if I should preemptively order a timer for my model. Does a failed timer happen very often? Mine is from 1971. And then, if I do need one, can I just give them my machine model number or do I need to know the timer part number. Would it be the same as the one for the KDS 17? Thanks so much, I've been learning so much from reading these boards.

Oh,could we see a picture of the 17?

Don't play that game, Mom!

Lisa,
Talking about the Superba timers here,the timers on the 16 and 17 dishwashers are as different as night and day!
And to make matters worse,IIRC,there were 2 different timers for the 16's as well. The 16's had a timer very similar to the 15 series in design (and not interchangeable either) and was mounted behind the front cross member in the right corner. The 17 series was the first to use the mono-block timers and it was mounted dead center below the tank on the Superba's. Probably the worst possible place to locate it if the motor should leak. And... the 17 and 17A's used 2 different timers as well!

If you have the ML-number from the data plate on your 16, I think I can get you both numbers and you can search for a spare timer. Just post it here.

The Custom and Imperial models all had their timers in the doors on both the 16 and 17's.Once we get to the 18 and up series, all the timers were in the door regardless of the model.

It will be a challenge to find a whole lot of spare parts for your machine but they are out there. Many people have found a donor machine from which to get parts so be on the lookout for one like yours as well.

and that is exactly the reason

firedome's profile picture
beyond the general overall engineering simplicity, that I prefer KDC-17 and KDI-17 to a KDS in the KA 17 series of machine... have looked at so many KDS-17s with minor or major leaks and/or corrosion on or around that silly timer right under the motor... what were they thinking? The 18 series machines that we have all have in-door timers... much smarter. Seems like an odd mistake for Hobart to make.

KD DW TIMER ISSUES

combo52's profile picture
All KD-10 through KD-15 DWs had the timers under the tank and the KDS-16 and KDS-17s also had their timers there and yes some were ruined by main shaft seal leaks that went undetected for long periods of time. KA should have added a decent water shield, but in spite of the timers that were ruined on KDS-17s by water leaks, the number does not come close to the number of timers with burned terminals on KDC-17 and KDI-17s, we had hundreds of customers with these that had two three or even four timers replaced before they threw in the towel and bought a new DW, even Whirlpool after they bought KA and assumed liability for these Hobart manufactured DWs was still paying for these poorly designed timers and cheap wiring when customers complained.

Thanks for the memories

John, you reminded me of some of the really dumb things they did when they made some of the wiring harnesses on the dishwashers.
What always stands out in my mind were the spade terminals on the timers and components that were not even solid spade terminals! They were hollow and just clipped on to the terminals with those thin sides.
Yep, got to wonder who approved that decision!

Just to say, the KDI-17a we had from late summer of 1975 until we moved out of that house in the early 1980s ... and then the KDI-17a that was already in the "new" house that went until the early 2000s ... neither one had any timer trouble.

Yikes...what have I done???

Oh boy, fellas, what have I gotten myself into? I will have to check the for the #'s you talked about. Can you tell me where I would find them? The owner's manual I got with it was for all 3: custom, imperial, and superba. Mine is the superba. I love this machine and it does such a good job.

I got it, btw, because my 10 month old $750 Kitchen Aid dishwasher has had to have service twice...in 10 months. Next time they come out I have to pay for everything because it wouldn't be under warranty. So I pulled that thing out, put it in the basement, and will put it back in when we have to sell the house. Modern appliances just cannot handle my family. I have moved to all vintage appliances over the last few years because they simply are better machines, have fewer things to break down on them, and I am able to fix them myself...to a point. Our family should work for Consumer Report because I can pretty much tell you the design flaws and breaking points of all the major (and minor) appliances we've had for almost 30 years. There's not a modern machine out there my kids can't break or wear out. But all my lovely older ladies are chugging along just fine.

Everything new has a motherboard on it and those have been a disaster for us. My new motto is: "There is only room for one "mother" in this kitchen (laundry room) and that's me."

Thanks for the help, Steve.

Lisa:

danemodsandy's profile picture
The guys are just pointing out some things KitchenAid could've done better. Those are to be found on any appliance. Your GE Combination probably has a replacement compressor, because the originals were duds, and many of them went kaflooey just outside of warranty, as the one on the Combination I grew up with did. So, there are weak points on anything, even vintage appliances we prize today.

Please remember that your KDS-17 has already outlasted most of the dishwashers sold in competition to it, and has the potential to go many years more. It's not a perfect machine - no machine is. But it's a damn good one. And no motherboard.

All 4 of the KDC/KDI-17s we have or have had

firedome's profile picture
have had no timer issues. The KDC-17 we bought new in '74 was still working perfectly in 1990 when we moved. That said, Steve or John, would it be worthwhile to go in now and replace the spades with better types? I do lots of soldering on the tube amps I work on so that's no big deal, and have 3 of these machines, so the wires and timers themselves were OK?

Termainal failures on KDC and KDI KD DWs

combo52's profile picture
Hi Roger, yes if I were considering using either of these DWs as a daily driver I would carefully check both the timer, selector switch and the door interlock switch for any terminal overheating and I would also replace all the spade terminals that carry the dry heater or main motors current with better quality terminals and crimp and solder them, you might also want use heaver wire. This was a major weak spot for heavily used KD17 DWs.

Hope this helps you keep these DWs alive, timers and selector switches for these DWs are getting harder and harder to find.
