How to Troubleshoot & Replace Ge AP3872943 / WD03X10026 Plunger Spring

Replaced door switches and plunger , spring. Other than the switches I believe the top of the plunger had contact issues as the updated part had larger contact 

Changed the water inlet valve for the water problem. To fix the problem of washer running while door was open, took off the front panel and changed the plunger sw interlock and spring which fixed the problem of washer running while door was opened mid wash cycle. Changed the clamp to the discharge hose as it had rusted.Changed keeper latch assembly as it had cracks on the plastic. 

Replaced plunger and spring. So far so good. 

I removed the screws to separate the inner and outer door parts, removed the switch cover, replaced the plunger and spring, then reassembled. It took 5 minutes and solved the problem. The issue was that the dishwasher didn’t think the door was shut because the plunger wasn’t activating the switch properly. 

New switch, just what l needed. Super fast shipping. Thank you. 

We replaced the interior door plunger, spring, and cover. The video from AppliancePartsPros.com was very helpful and made the job very easy to complete. 

Replaced interlock switch, interlock switch plunger and plunger spring. Dishwasher now working and wife is happy.

Had the same problem before. Talked with tech on phone we figured out what parts were needed.
