Removing Chopper Cover

I have a six year old Whirlpool dishwasher that has a loud humming sound while the motor is running. I have tried to remove the chopper cover after removing the two square drive screws, but it is not budging. Is there some trick or catch release that I am not aware of? Thanks.

    Thanks. I don't want to trouble you any more since further help probably requires getting the Premium Assistance Plan, but I sure would appreciate learning how to pull the pump motor assembly. That seems like a lot work, or else it's simple and I'm confused by the terminology.

  • RicN Feb 29, 2008

    Thanks for trying but the tabs are not as they shown for the Kitchenaid. My Whirlpool doesn't show any tabs. It seems like they are hidden, or prying might be necessary. I don't want to break anything so I'm still listening the noise. In summary, it seems the tabs are different than the Kitchenaid.

Starting the dishwashing cycle, extreme loud noise when dishwasher starts pumping water. Loud noise stays during pumping cycle. Dishes are clean and dry and no water in tub when cycle finishes.


If your unit is a Kenmore or Whirlpool (there are several other brands that use many of the same parts) and is less than 6 years old then it may pay to first check and clean out the chopper assembly for hard debris. If that doesn't do it then you may want to consider replacing the motor and circulation pump as a complete unit for between $160 and $200. Not too difficult a task for a moderately handy guy with some tools. Maybe 2 hrs. The bearing itself is not serviceable I understand, and would be considerably more difficult. Over six years old then you can buy a great quality machine for about $500.

I also can't get the chopper cover off my dishwasher.


My chopper cover was held in place by two screws, but even after removing them I found I needed to use a pair of 'channel lock' pliers to grasp the plastic cover and pull it up and off. Yours may just be stuck from a few years of use and thermal cycling.

Putting the whole thing back together was an equal joy...

Dishwasher starts to fill then just hums


Sounds like a motor problem. Behind the chopper is an access to the impeller, try turning the impeller or the chopper blade and see if the motor will rotate. If it doesn't, then something is stuck preventing the motor from running.

Loud Whirring Noises


very possible that it is indeed something stuck in the chopper assemble, remove the lower wash arm, from ther youll remove 4-5 torx15- screws and then under there you find another torx 15 screw , after removng the screw you can pry up hte cover form the right side and reveal the chopper assembly, i would refrain form removing the chopper if at all possible, its kinda a pain in the rear to put back in, buit you can cean any junk out if ness.

Loud whining noise while washing


It may be debris in the food chopper or the motor going bad.

Inspect food chopper:
Remove lower spray arm and rear water supply tube to upper spray arm. Remove torx screws that secure the sump cover. Remove the rounded cover on the left side to expose the chopper assembly. Inspect for breakage of blockage. There may be an additional plastic screen to remove first.
