Our dishwasher started making a vibratory loud noise last week, the top rack quit coming clean, so I replaced the water inlet valve and took out the chopper assembly. It was gooped up quite a bit. It seemed to clean better but then quit again and is still loud. I took it apart and the chopper was gummed up again with food. I cleaned it again. Turning the chopper blade will not turn the motor unit but I an manually turn the motor unit and the blade turns. Does the chopper unit need replaced or is the motor going bad? Thanks
Answer Hello Scott,
The chopper has to be bad since the food is stopping up the screen. This is a common failure but the fix will correct the issue until something hard gets into the chopper area again. I do recommend to use a wet-vac to suck out the water and whatever debris is down in this chamber. The reason I have made this a habit is because many times there will be a small, clear piece of broken glass in the chamber and since you cannot see it, it will break the new part and make you have to execute the repair all over again.
There is no lights on panel but power to the unit. Could the motor be burnt out? The unit didn't finish last cycle. What else could be the problem?
You will want to check the control board to see if there is power getting to the control board. If there is no power getting to the control board then the issue would be caused by either loss of power from the main source or the fuse may be blown before you get to the control board. If there is power to the control board then the control board would most likely be the issue. The part number for the control board would be 8564543 and the fuse is 8193762.
I took the cover off of the chopper assembly. Should the chopper blade turn freely or is it designed to not turn during cleaning?
Answer Hello Kelvin,
The chopper 8268383 should be turnable but it will not turn freely since it is attached to the motor on the backside. You should remove it and make sure the assembly is not damaged. If there are a lot of food particles on the screen it has most certainly failed.
Followed online tutorial on dishwasher because dishes were not clean. All went well until reassembly. The chopper assembly is making horrible noise when running dishwasher. Is there a trick to getting the chopper assembly back in correct position? Additionally, it does seem chopper assembly is in good condition,
Answer Dora, Yes, there are several things to check and verify when you replace the chopper screen and blade. When you removed the original screen, you need to check the tabs in the cenetr of the impeller 8193951 (black area) make sure the tabs are not damaged or worn. The tabs on the back side of the chopper blade/screen have to engage the tabs on the impeller, in order to drive the blade and cut up the soft food particles. You also need to check and make sure there is nothing inside the impeller housing, that will create a noise as well. The screen and chopper blade do have to be installed properly and then the protector 8531857 needs to be installed after you're sure the screen and blade are installed and engaged the tabs of the impeller.
