Do-It-Yourself Stories from Customers like You Blown dishwasher pump.   Paul M. • Littleton , CO • December 10, 2018

I called AppliancePartsPros, talked to a technician to validate problem, ordered part. I had a great talk with the technician. Told him I have electrical engineering experience, used to fix pinball machines and that the pinballs and home appliances were the same design, i.e. inductor in series with a switch across the hot lines. After that the conversation was like two long lost cousins talking at a family barbeque! Great customer service! Read more

Do-It-Yourself Stories from Customers like You Water at bottom of dishwasher after a complete cycle   Jeffrey B. • Granite Bay , CA • February 15, 2021

Replaced the control board as it was intermittent. This did not solve the issue, the pump would no longer run at all. Then I replaced the waste pump after the board replacement and this issue was resolved. This in fact fixed the machine. Water had broached the armature shaft seal and allowed the pump to run intermittently for a while after the breach. Happy to have a dishwasher again but not happy that I am the proud owner of two control boards that work now! Oh well. Read more

Do-It-Yourself Stories from Customers like You Leak from under KitchenAid dishwasher misdiagnosed by technician   David B. • Freeport , NY • August 21, 2020

My dishwasher was leaking and I called to have a certified technician come to diagnose the problem. I removed the kick panel from the bottom of the machine. He turned it on and we saw that water was leaking from the bottom. He said I needed a Sump kit but it wasn't in stock. The cost was $170 plus tax and labor cost was another $140. So I talked it over with dad and ordered the Sump kit, the hose clamp and a new diverter motor as mine was yellowed with age. The cost of all these parts and... Read more

Do-It-Yourself Stories from Customers like You Machine running loud grew worse until it was obvious the motor blew a bearing   Robert S. • Bettendorf , IA • February 21, 2015

We initially noticed the dishwasher running loud and failing to completely clean dishes. Research suggested issues like this were normally caused by either the main circulation motor or the drain motor. Over the next week the noise worsened, and it became obvious that the circulation motor had went (loud whirring noise whenever the spin cycle kicked in).

I reviewed the schematic and saw the Volute Seal, and Impeller Seal were the two that were closest my source of water. After watching the video about changing the Impeller/seal I removed the motor, impeller, and volute; I found that the impeller seal was the faulty one in my case. Since I'd ordered the volute and impeller seal kits (as I wasn't sure which it was) I installed both while I had it apart. Runs great, no water - simple to do. The seal changes took about 20 minutes.
