Kenmore Dishwasher Impeller? 665.13752k601 - Is it worth DIY?

9 posts in this topic

Hi Wise Folks,

 

Loud grinding noise was similar to what we heard when there was sippy straw and twist-ties in there.  That time (6 months ago), the noise went away after appliance person took it apart and cleaned it.  THe water also flowed better, and got things clean.

 

Now the noise is back. I have cleaned the mascerator (1st blade/screen in sump).  Did not fix the problem.

 

It only seems to happen in the wash cycle, not rinse.  Don't recall if pre-wash/rinse.

 

The unit has given 8 years of service, would like more.  Everything else works fine.  Just the noise.

 

Read somewhere that it could be a second level screen, or even the impeller.

 

Looks like I have to remove pump to get at these.

 

If I have to remove the pump (even if just to replace the impeller), is it worth getting a new pump (and related seals) and new impeller--and fixing the thing?  Are there other "wear" parts (e.g., sensors, water pump) that are considered fragile and should be replaced?

 

I am very handy, though this seems more "involved" than complicated (I downloaded a Whirlpool manuial to read about the steps).

 

Is it worth it?

 

Advice Most appreciated.

 

JBR

Sounds like a noisy motor. Water leak into bearings over time causes bearings to gradually get louder. Very common on this design.


Run motor with macerator removed and confirm if you still here noise. If so bad motor. You can get the motor itself or  as the whole sump assembly included. Either way machine has to come out to replace it.

I agree with MA tech on diagnosis procedure. This is not too difficult to replace and is well worth it, imho. I like this design much better than many of the newer ones. 

 

Its a long shot, but you could try running some Lemishine Dishwasher Cleaner through it in the odd chance that it may break some deposits loose for you.

I'll agree its probably a bad motor. There is a chance you may have something stuck in the impeller housing thats causing the noise, but to check that you're going to have to pull the motor out and look in there. If you're not wanting to spend money on unneeded parts  maybe pull the motor first and see if there is anything in there, and if there is clean it out and reassemble it. If there is nothing in there order a motor and replace it.

Thanks all, I really appreciate the "Crowd" opinion shown here.  I have used it for HVAC issues and choices (HVAC-Talk), complex alarm choicesand installation issues (DIYSecurity), and now with kitchen appliances.

 

I can't imagine removing the system and not replacing Wash Motor/Sump. and possibly even the water pump.  Removing the unit seems to be the largest cost.

The motor-sump assy can be replaced without removing the dishwasher:

Hi, and thanks for the video.  I replaced the sump assembly, and the drain pump and optical sensor.

Best running 8 yr old system.

 

Point on the video: neither this video, no any other I could find about installing the sump assembly, indicates the location of the three clips--and what to do with them.  FOrtunately, I found a diagram with the location, and figured it out.

 

Great DIY anniversary present--even though I usually do the dishes!
