A Kitchenaid repairman came to look at the dishwasher and found that the rotor needed to be replaced but none were in stock. The part was on backorder and the price would be $75 plus a $55 installation fee.
I went online and found the exact same part at PartSelect for $37.98 plus shipping and when it arrived, replaced the defective rotor easily. Now the dishwasher is whisper quiet like it was when new. I saved a little over $80 by ordering from PartSelect and replacing it myself.
IF PartSelect had sent the part I ordered all might have worked. I paid the shipping for my needed part. The wrong part was returned at my expense also. You cost me $16. and I got nothing but poor service.
took the racks and plate of dishwasher out wiped out center circle where impeller and center ring fit. the center circle became blocked with food so i had to clean it.
