Do-It-Yourself Stories from Customers like You There were two problems one of the spring links on the door broke which meant the door would free fall when opened unless you held on to it also the lower bearing on the motor virtually seized up   Randall B. • Moab , UT • January 14, 2017

I first wanted to get the dishwasher running, before ordering the spring links. So I disassembled the pump / motor assembly to determine the reason the motor would not start. My wife cleaned all of the parts in the pump assembly. I took the motor apart and discovered that the lower bearing ( a sleeve type bearing) was dry and dirty, and was the culprit for the motor seizing. I cleaned up the bearing and lubricated it with SAE 20W. I also packed felt inside the cavity adjacent to the bearing.... Read more

Do-It-Yourself Stories from Customers like You Dishwasher door broke   Vincent D. • Collingswood , NJ • January 25, 2020

So I noticed a few months ago that the dishwasher door felt a lot heavier than it used to. Then just recently I opened it and heard something snap and the door came crashing down onto my foot! Ouch!! The door was still able to close but opening it required it being fully lowered by hand. I had no idea how heavy the dishwasher door was! So I got down onto the kitchen floor with a flashlight. I removed the metal panel at it’s base by lifting it up and pulling it out. Once I was able to get a... Read more

Do-It-Yourself Stories from Customers like You Dishwasher started making a grinding noise   Timothy T. • Alpharetta , GA • June 26, 2015

Searched the dishwasher model on ApplianceParts (had used them for a washing machine repair a few years earlier). Was looking for an exploded diagram of the internal parts so I could figure out what might be the problem. There was a video for a motor seal repair kit that seemed to address the bearings which is what I suspected was the culprit. The video started by noting that "you want to replace the motor seal if 1) you have a leak or 2) your dishwasher is making a noise". I watched the... Read more

Found the retaining clip on the parts list. Watched the videos to figure out how the upper arm attaches. Tried cleaning out the terribly clogged upper arm. Then looked at the lower wash arm--WOW!

Got the lower arm off and realized all the gunk I was able to poke out of the holes would just come back, so replaced both spray arms. YES, the upper arm includes the retaining clip!!

I ordered new racks, volute and check ball, and new spray arms. Replacing the volute and check ball were the hardest things to do and they were fairly easy to change. The toughest part for me was finding my T15 torxdriver. After replacing these parts the washer operates much better with much higher pressure than what we were experiencing recently. Read more
