Our 12yo Kitchenaid dishwasher (model kuds01dlss6) used to run quietly but now makes a loud, consistent groaning noise during the wash and rinse cycles. The drain and fill cycles are still quiet. I removed the parts inside the dishwasher down to the food grinder area to remove any foreign objects - which there weren’t many since we rinse in sink first. I also turned the impeller via the grinder and it seemed to turn smoothly. However, the sound still persists. With the bottom front panel off, the sound definitely appears to be coming from the circulation pump area. From what I have read, the motor bearings are the likely suspect given the potential of a shaft seal leak and the age of the dishwasher. Although I saw no signs of leaking from underneath, I know from pool motors that even the slightest of leaks can rust out the bearings. A replacement pump/motor can be had for less than $150. Would anyone who has done this repair care to comment on difficulty, other issues that may arise or if I am barking up the wrong tree?

Also, given the dishwasher is 12 years old, are there other commons issues that I should look for or consider before deciding to repair versus replace? Not sure of the longevity of these dishwashers. From poking around the inside, everything look in decent condition except for one or two rusted rack tines.

Thanks in advance for any advice.

Thanks for the video and buying tips. I assume the video is comprehensive but are there any tips on this repair?

Also, I assume this means folks think it is worth repairing even though the rest of it is 12 years old. Are there any high failure parts I should replace while I have it out or just do the pump/motor?

I've thought I could sneak by with replacing the chopper assemblies and the impellers.... Every one I've done has leaked...

It is easier to purchase a sump with the motor attached and call it a day... I wish I would have done that in the first place on the last two and now I've got to go back and do it.

on repairclinic.com the whole motor sump unit is cheaper than just the motor alone!

Noisi dishwasher

It sounds like you’ve narrowed it down to the pump and motor, I have never had any problems just replacing just the motor on these DWs I do several every week

Bear In mind that your pre-rinsing is what causes the seal failure and rusted racks, pre-rinsing dishes generally cuts the life of a dishwasher in half. Dishwashers were never designed to wash clean dishes without food soil, the detergent is too strong and temperatures are too high.

Pre-rinsing....this is so true...

especially for dishwashers with 'Sensor' cycles.....with no food particles, your wash time could be reduced, and it will jump into final rinses, 2 if your lucky...

just because you press 'Heavy' or 'Normal' doesn't guarantee a full cycle....something to think about...

Well if the pump and motor together are cheaper than just the motor, I guess I might was well do the pump/motor assembly.

Regarding pre-rinsing, I had no idea that it could be a bad thing. We scrape off excess food and will rinse them in the sink. There is some stuff left on there but clearly not as much as if we just put the used dishes in there. This model does start with a 'sensing soak' if that matters. I always thought that introducing more food particles could increase the chances of dishes coming out dirty. However, after 12 years of use, did I really shorten the life of the dishwasher that much?

if you want to give it a challenge, throw a whole cake at it once in a while....

I haven't done that to my UltraWash in years....but after the first few times, I figure it could handle anything after that....

this gives me an idea, I need to throw one into my Kitchen Aid....maybe I will bake one tomorrow...

any great dishwasher can have his cake, and pulverize it too!

I imagine you've been using your normal cycle and hopefully not adding any options.  With your dish prep habits, I'd suggest all you use is the quick clean up cycle.

@appnut, we regularly use the normal cycle and the energy saver dry. What's the difference between normal and the quick wash cycle? Would that quick wash cycle not have worn out the pump/motor as quickly? Less wear on the seals?

Well it took 9 months but I finally got fed up with the noise from the old pump. It was getting harder to find convenient times to run the dishwasher without it waking people up or annoying those watching TV. The pump/motor combo was about $90 on Amazon so I bit the bullet.

Did the install today and I really took my time having never done a dishwasher removal/install before. The hardest parts were dealing with the copper supply line under the dishwasher due to the low clearance and getting the pump seal to fit evenly enough in the opening to get all 3 clips in. But it's done and seems to be watertight so far (knock on wood). And it appears to be about 10dB quieter than the old one according to some phone sound meter app, but it sounds quieter regardless. Not sure if it is as quiet as it was several years ago, but it is better for sure.

Thanks again for all the advice. I am putting off dealing with the rusting tines (there are several more now). Just don't have the energy. I'll see how well this pump holds up before investing anymore time or money in the old machine.

I replaced a 12 year old Asko with a Bosch 800 series (SHPM78W55N) earlier this year. After using for six months, not sure that I would get another Bosch. I mean, it cleans very well and is very quiet and because I had the Asko, I was used to the drying and interior and rack issues. But the Asko was just a beast re. water temp. and sanitizing. (Although I've taken to running all of my loads with the Sanitize option on the Bosch, I'm not sure that it is quite the same thing.) I priced an Asko, but would have run me another 300 or 400. Also, any thoughts/experience share on the models from the link?

Thank you - Seara

If you're still in the habit of pre rinsing, please use less detergent. You put things almost clean into the dishwasher, detergent has nothing to work on and that will have negative consequences for seals and pump.

Seara,

Your question is off topic in this thread, it would be better to start a new thread about it.

pre-rinsing

It just kills me how so many people are so stupid when it comes to washing dishes. They constantly baby their dishwashers by pre-rinsing their dishes then complain they're not getting clean dishes. Gee, I wonder why? They're not doing the dishes properly. They're supposed to just scrape and load. That's it!
