Water washing out under front door onto floor

The plastic parts on this spray arm assembly wear with time and the rotation wobble effect creates a wave action in the pool of water at the bottom of the dishwasher. This waves the water onto the front door and forces a leak outside the unit. Replace the lower arm assembly, washer, bearing and nut. They all wear. Also remember to tighten the screws on top of the pump assembly. They loosen and aid in the wobble. Good Luck!

Dishwasher wouldn't clean dishes, left white film

After reading the diagrams and other readers' repair stories, I found that the plastic nuts and rings had worn out. The arm-spray wobbled excessively.

I simply twisted off the spray arm bearing ring and removed the other parts. The arm-spray was covered with mineral deposits that cleaning did not remove.

I received my parts overnight and replaced them according to the diagram. It's like having a new dishwasher!

Lower wash arm nut twisted and broke off

remove the lower arm and pieces.. get the parts stacked in the right order and hand screw the retainer nut... done! I decided to spend a little more and replace the whole washer arm and I'm glad I did. My dishes are coming out clear then they have in years!! Ordered the parts Thurs morning... thought i might get a load or two done but when I opened the washer on friday it was obvious I was facing a weekend of teens having to handwash dishes! 15 minutes later the doorbell rang and there were the parts!! Woo Hoo!!
