Latch Handle WD13X10007

opened door removed screws holding back side of door took out front panel with latch assembley found broken part and replaced it

Remove the screws from the door and replace the switch interlock and door latch.

The problem is fixed and the dishwasher works fine so far (about three weeks) now.

The source of the problem looks more like the door latch because I use to push the door in to get it going before I replace the parts.

The video I received via email that show the how to do it was very helpful.

Update after more than month. (12/30/2020)
The problem still persists. However I have a possible solution for it that doesn’t require any parts at all. The entire dishwasher is tilted backward. As the washing started and the water pileup in the bottoms of the dishwasher, it pull the entire dishwasher back work causing the switch interlock to release (open the relay causing the door open been sounds).

Level the dishwasher so that it doesn’t tilt backwards and this should fix the issue. I will post the latest after a month. If you need more info I can send a picture to describe the issue more clearly.

The problem still persists. The above theory I had was wrong and didn’t make any difference.

However, I have a permanent solution but it may not be ideal for most people ??. The relay that get close/open when the door is close/open is now always CLOSED. To start the dishwasher just press start and make sure you don’t open the door while the dishwasher is running. It will not stop. I am sorry and I know it’s not a good solution but it’s kind of funny.

Removed top screws to allow the ability to remove control dishwasher control unit. Remove door parts & be careful how you remove them & put back the door parts the same way.
