Jennair dishwasher model # JDB1100AWB

[maypo52]

Hello fellow diy'ers and pros.


My daughters Jennair dishwasher model # JDB1100AWB Is having a problem. It is not spraying water. It does fill with water but is not being circulated through the spray arms and when the cycle ends it does drain properly. I removed the lower spray arm and all the bits to expose the impeller and it all looks ok. The impeller turns freely by hand but I am not sure if the pump motor is running during the cycle. I hear a hum but no water splashing sound. I even removed the pump filter assembly to see if there was anything there to prevent the motor from running but nothing obvious. I'm thinking maybe the pump motor has failed but I'm not sure. Is there anyway to test it without removing it? Are there some other tests I can do?


Thanks for any help you can provide.

Below is a link to a service manual

Here is a post about a problem area in this unit.
Take a look at the Dishwasher Seal Kit in Tq999's third post.

And finally here is a link to a post that has the tech sheet

You could remove power from the unit and check the motor windings.
Also you could check the motor capacitor but checking theses is difficult with a standard meter and they may look OK but still be bad. They are usually not the problem.

@manden  Thanks so much for the info. I will give it another look.

I ordered the motor seal kit and unfortunately it did not include the coarse threaded sleeve, which is the one I needed. Apparently Whirlpool decided to remove this part from the kit and expects you to buy a new motor instead.    Does anyone have a source for a motor seal kit with both coarse and fine threaded sleeves?


Thanks,


Mark

A quick update: Found a motor seal kit on ebay that had both sleeves. It did fix the problem.
