Hi folks. Very simple question from an absolute beginner. My dishwasher, a Kenmore Elite 655.15933000, is very noisy and cleans poorly. I've read around enough here to confirm my suspicions: that there's a piece of glass or something jammed in the food chopper/masticator or whatever you call it. I'm ready to dive in and dig it out, but...I can't get started. I'm not sure how to remove the lower spray arm. My guess: I need to hold that little flat piece that sticks up from the middle with a pair of pliers (gently) and turn the arm to unscrew it. But I tried that--didn't want to force it since I wasn't sure--and it didn't budge. Is that the right idea?

Any other tips for getting me inside? Or will it be obvious how to take this thing apart once I get that spray arm out of the way.

Thanks,
Jim

Okay next question. I got the lower spray arm off. And removed the three screws holding the next bit in place. Now I can't make anything move. Looks like the next step would be to remove the "internal rear-feed cap," as the parts list calls it. Also, the thing underneath it with the screen--haven't looked that up yet. It looks like it ought to rotate and slide out, but I can't make it budge. Is that the right approach?

Thanks,
Jim

This dishwasher problem's got me talkin' to myself...

Thought I'd add a note on what's really confusing me. I removed 3 torx screws in the screen over the accumulator. But there's a 4th screw I can't get to because it's underneath what the Sears parts list describes as the internal rear-feed cap. But that part--the round part that fits over the lower sprayarm hub--is held in place by the plastic frame around the acumulator screen--the part that's held in place by the screw. So I can't get to the screw without removing the "internal rear-feed cap" and I can't remove that without removing the 4th screw.

Grasshopper need help here, please.

Thanks,
Jim

Now I'm really talkin' to myself. And now I'm really stuck.

I keep chuggin' along. Now I've got the accumulator out, looking directly down into the sump. Couple of pounds of nasty slime; no wonder my dishes aren't getting clean.

But now on to the next challenge: it looks from the parts diagram like I ought to be able to remove a cover from the chopper assembly. Part #8 on the sears drawing, called an "inlet protector." I've removed a screw--two screws, total, including the one holding part 9--the "foreign protector" in place. But the "inlet protector" ain't budging. As usual, I don't want to force it. What's the trick?

By the time I'm done I will have solved my problem and written a whole tutorial, all by myself.

Cheers,
Jim

Thanks,
Jim

Sorry no one has helped you Jim, seems like there would be ones in here that take those apart.  But you are doing a real good job!!  We just replace the whole pump and motor assy as a unit since it is difficult to get them back together with them working right and not leaking.  Hoping the right person will come along and help you...;)

Thanks, Pegi. Seems I didn't really need help anyway. Just kept plugging along and eventually got inside. Found the food chopper assembly completely disconnected, just floppin' around in there I guess. It's a $10 part. So if I can just manage to get this thing back together (I don't think I disassembled anything that's supposed to be water-tight, except the hoses) I should be in business.

Can't believe how much gunk there was in there. Probably a quart of green/black slime. Is that normal, or is it because the chopper was broken? Or something else? I mean, it's hard to imagine getting anything clean in a tub with that much grunge.

Thanks,
Jim

Does not sound normal, sounds like that mascerater blade could be causing this problem and was probably the noise also.  What kind of det. you using.  If it is liquid or jel this will cause all kinds of damage as the clay in them used as a binder will clog the dishwashers.  Use a powder like Electrosol, and be sure to run the water at the sink first to get the water hot before turning the unit on.  You need at least 120* going in, but 130-140 would be better to disslove the soap and clean the dishes

I've been using those little cubes--Electrosol I think--that look like compressed powder. Are they okay?

Thanks,
Jim

Hey that's my dishwasher!

The door looks the same anyway, as my Kenmore Elite. The panel layout is a little different, and the brand tag on the Kenmore is below the vent on the left. But otherwise it looks exactly the same.

Hope yours works better than mine does. It has only recently started making that terrible noise, but it has never cleaned all that well, and normal cycle takes forever.

Thanks,
Jim

Had ours for over a year and is the dream machine, but it would not dare break since I know what to do with it and Randy, being a retired cop with guns, well, you get the idea..plus we bought an extended warranty, a must these days with the stuff they are putting out there. :cool:

Jim,

I am having a similar problem with my Kenmore dishwasher. I took it apart, and cleaned everything out, but am still getting a grinding noise when it is operating. I got as far as trying to remove the "protector inlet" which houses the chopper assemble, but, I cannot get the protector inlet off.
How did you do this?

Larry-san

Larry-san,

I finally managed to get mine off, but it's been a while and I don't remember exactly how it works. I DO remember that there were two (or maybe three, but I think two) torx screws I had to remove. It seems to me that one of the pieces had a plastic tab--on the right side of the assembly--that had to be compressed to slide it out.

Aside from that my best advice is just to have confidence that it'll come apart without forcing it. If you're sure of it, then it will.

BTW: though I managed to replace the chopper assembly, it's not as quiet as it used to be before it broke. But that might be because I didn't reinstall the soundproofing quite right.

Jim

I have this same problem when trying to take apart a Kenmore 665.16263402 dishwasher to see what is causing a loud noise. How did you remove the fourth screw and the internal rear feed cap?

Can anyone explain how to disassemble these parts so I can check out the chopper assembly?

If I need to replace the motor, is it done through the inside rather than by removing the dishwasher from the cabinet?

Here goes-- hope I don't confuse everyone...   Slide the top rack out a few inches , grab the rear feed cap where it is joined to the tube feeding the middle spray arm, Now pull(or push) them both to the right. they will move enough to come apart. Now you can remove the part to get the 4th screw out. Some d/w have 2 smaller screws to take out now , some of the newer ones only have 1... If 2 screws , the part on the right should lift off easily , then I put a screw driver in beside the plastic tab on right hand side of the left side cover and give it a flip up (confused yet?) or take a pair of needle nose pliers and give it the heav ho.  The hardest part for me is getting the "+*)^$%#@##@@~~_()*&+ screen and emacarator back on  --  so you are on your own now.  Very seldom does the motor bearings go , but it would be advised to change the whole assembly if needed.:shock:

Thank you. That helped quite a bit. I think I should clarify a little, though, for anyone else in the same predicament:

As you suggested, I pulled out the upper rack a little to disengage it from the water supply tube in the back. But to follow your instructions for moving the internal rear feed cap to the right, I had to do something else first. On this model, there is a spring clip in the back and another on the top of the tub. These two clips hold the feed tube assembly tube that supplies the spinner at the top of the tub. To allow the whole tube assembly to move to the right, I had to gently pull the tube assembly out of these clips.

With the top and back of the assembly free, I was then able to move the internal rear feed cap and the tube assembly to the right and then separate the feed cap from the tube. Then I could remove the fourth screw and pull out the accumulator assembly (the thing with the nylon-like screen.

Now I am wondering what to do next to remove what the diagram calls the "sump with seal" -- if that's even the right thing to do. So far I have found no foreign objects other than a piece of paper in the accumulator area, so I suppose bad motor bearings are still the most likely cause of the grinding noise.

OK, another inch of progress, but I'm stuck again. There was one additional screw under the accumulator assembly. Then I used a screwdriver, as you suggested, to release a plastic tab that held down the thing that Kenmore calls the inlet protector, which I think is what you called the left side cover. Under there I found a small piece of ground-up plastic tape, but nothing that I think would make much of a noise.

So now, as you can see in the attached photo, I can see the chopper assembly, which is basically a metal mesh wheel with a little impeller on it. At this point I have no idea what to do next. Either the whole "sump with seal" assembly is very tightly held in (which I suppose it should be so it won't leak) or it's very heavy, which I suppose it is, or it's still fastened to the bottom of the tub somehow. Am I supposed to be able to pull it straight up? If so, how? I'm reluctant to mess with that seal much with a screwdriver or something, because that  might damage it.

What next? :(

If it is as clean as it looks , you are good to go. We want nothing down by the screen and blade ..  Put the parts back on and give it a test. If it is still noisy , the only other moving part is the motor bearings. .. Going on a 5 week holiday back to Saskatchewan to sponge off the kids for a while and visit on the way there and on the way back to Vancouver Island , so other more informed people here will help you if needed.  Good luck!:D      I never worry about carefully undoing the clips on the feed tube - so far so good.

Thanks, but if I do need to replace the motor and sump assembly, how do I get it out from this point?

An update: I put everything back together, and the dishwasher still makes a loud noise while washing and rinsing. It's constant, and more of a "scraping" than a "grinding."

Can someone out there please tell me how to replace the sump and motor assembly?
