Door would fall open
Removed four screws on bottom plate. Located repair site on outside of cabinet. Had to hook spring on bottom rear plate by brail. Then attached linkage to spring and ran stiff wire through linkage to raise it above arm. Called a man with stronger but larger hands had him stretch the spring while I guided linkage over arm and into the slot using the wire. Removed stiff wire with needle nose pliers and reassembled front plate.

Upper spray arm falling off during wash cycle
Unscrewed old nut, inserted new nut into new spray arm and screwed the assembly back in. Took less than one minute. Requested the 3-5 day delivery and received parts on second day. After examining the old and new parts it appeared the nut was the only part I would have needed, but since parts were less than $5 each I did not want to take a chance. Total cost was $16, the shipping being the most expensive item but much cheaper than paying for a service call.

My spray arm kept falling off
I ordered the new spray arm and nut, snapped them together, screwed the nut onto the screw and started a load of dishes. That's how simple it was. Glad I found your website. Thanks.

accidently broke the drain valve lever lifter while fishing around looking for a filter to replace
Once I pulled the old broken drain valve lever lifter off the shaft, the shaft rotated counter clockwise. I then had to turn shaft back clockwise so there was enough room to slip the new part on. Needle nose pliers worked great to hold it in place while regular pliers in the other hand was used to turn the shaft.

Leaking from the dishwasher on left side
Took off the float, the jam nut was hard to get off, we ended up breaking the bottom piece of the float to get it off, but that was okay because we had a new float. The new float went on real easy and the jam nut went back on real easy. The foam insulation strip was real easy to get off we got a good hold of one end and striped it off slowly so there was nothing left on the door, then we cleaned the surface and put on the new insulation strip. We ran dishwasher to test it and there was no leak. Awesome. Cheap and easy to repair. We were impressed.

Close door, turn on dishwasher, walk away. 5 to 10 min later dishwasher not running. Push in at the door latch and dishwasher would start back up.
Removed the inner door panel-Removed the black cowling covering the timer and wires.
Removed the swicth assembly and installed new part.
Reassembled dishwasher.

I checked the operation of the two switches. One switch did not click, when button was pushed, as cleanly as the other. There was a bit of delay and play in the button when depressed, even sticking a bit.

Remove bottom cover.
Put the belt on the large pulley and stretch it about 5 times to make it larger. Remove the belt from the large pulley and put it on the small pulley at the motor. Stretch it to left side of the large pulley and make sure the belt is on partial of the pulley's groove then rotate the large pulley forward. The pulley will pull the belt into the groove by itself.
