Kenmore Dishwasher grinding and not draining

Hello all,

For a period of 2-3 months my dishwasher has not been fully pumping the water out of the tub at the conclusion of a cycle. To clear the water I had to select cancel. Now the dishwasher makes a grinding sound and will not drain at all. In fact any cycle I select causes it to make the grinding noise. While manually draining the tub I found some broken glass. Is it possible that glass in the pump could be the problem? If so can someone tell me how to check. Do I have to disassemble it?

Please help I have a big family and I need to repair it or replace it asap.

Thanks,

Mike

Please post all of the model number.

Sorry, I missed the first three numbers. It is 665.15714000

Without actually checking it myself, I would say the pump is going out (possibly due to the glass getting into it) but the grinding may also be from the motor.
Although my opinion would be to replace the pump & motor(part #AP3776466) you may want to look inside the pump to see if anything looks damaged from the glass or whatever else maybe in there.
This is one of the best pump & motor designs, again in my opinion) that Whirlpool made. And they don’t put this design in the new ones.

If you don’t mind can you tell me how to check for debris in the pump? I’ve never taken one apart.

Start by removing the lower spray arm and then the bolts on top of the pump, keep going until you find any debis (just remember how it goes back to gether) If you need to see a breakdown go to searspartsdirect

I can’t hold the 1" hex on top of part 11 and unscrew the 1/4 inch screw the holds it on. Any hints?

We generally wedge a screw driver, carefully, down in there to hold the upper impeller (#11) and then you can get the 1/4" bolt out.
Nat

Sorry to keep bugging you but can you tell me if I loosen the screw clockwise or counterclockwise. It is so tight and small I’m afraid I’ll break it if I go the wrong way. When I spin the upper impeller manually it sounds like its hitting on something.

That bolt should turn counter clockwise.

BTW… It’s not a bother I volunteer what I know on here all the time ;o

Finally got the impeller screw out and removed the screen. I removed a penny and several pieces of glass. I noticed 2 white plastic balls under the screen floating in the undrained water. They are smaller than a marble. Are they part of the assembly? Are there any gotcas when I put it back together? Does the screen assy go on a certain way? Thanks!

the balls are ceck balls they do have to be there! As long as the screw hole line up on the screen part you should be ok.
Nat

Do the balls have to be installed in a certain place? As I said they were floating in the left over water and I really can’t tell when I look at the parts breakout.

Thanks again.

Here is a picture of the breakdown. The check balls go under #4 on the picture.

Thank you so much I removed about 6 pieces of glass and a penny then put it back together and it works. I really appreciate your help.

You’re very welcome…Glad you were able to get it fixed.

Nat,

I thought it was fixed. The grinding stopped but it isn’t draining all the way after the cycle. I used to be able to press cancel and it would drain. After the cycle the bottom was almost completely full of water and after I pressed cancel it cleared some but not all of it. When I put the check balls in I placed them in number 4 which basically looks like a reservoir and they are trapped there by part #9. Is it possible I’ve placed the check balls in the wrong location. It really isn’t draining much at all and that is a new development.

Thanks,

Mike

Check you drain lines too they may have some debris in them as well.

I see you are the one to come to with ceck ball issues! I have taken apart my dishwasher and I found the problem (the spring came loose), I have fixed the initial problem, however, I’m not sure where the ceck balls go. (as they were just floating when I took the cover off) There are 2 ceck balls. Do they both go in the r[SIZE=2]eservoir looking part? (#4 in a diagram I have seen you use before)?

reading this two plastic ball issue this may explain alot with my dishwasher: model 665.1569992 last spring I took it apart to completly remove all the calcium deposits, and it had been sitting idle for 6 months. when I took it apart there where these two little balls sitting in that oval hole in the diagram where it shows parts #5 and 7 go. I thought they where debris, and tossed them away. I know know they where part of the check valve. So can I get replacements? if so , where, and how much.

Also how do they work?? I mean what do they do? float when full? and what is happening actually when they are not there?

my main problem is not enough water pressure to turn upper arm, water comes out of top and arm holes but not enough to do any cleaning, is the ball absence the problem? or is the low water level a problem of thown away balls? (both as cuase and effect?).
