Sorry, we couldn't find any existing installation instruction that matched.
It makes a beeping sound in the middle of the dishwashing.
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.

Update 01-06-2021
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.

Dishwasher did not start
The repairman diagnosed the problem as a control board failure and quoted a $350 bill. I self-diagnosed it as a failed interlock switch -- and found out that the switch was OK but the cover was cracked, preventing the switch from functioning normally. Total repair bill - $1.50!

First I removed the 6 screws that hold the inside cover on the door.Then I remover the plastic cover over the switches,pulled out the switches and disconnected the 2 wires from each switch and connected connected them to the new switches exactly as they were on the old switches.Then reinstalled the switches in their holders.I then removed the plunger and spring from between the switches and installed the new spring and plunger exactly like the old one was installed.I reinstalled the door cover making sure everything was in it's place,I put the screws in the door cover and I was done.It was a very simple job.

This GE dish washer does not stop it's functions when you open the door if it is spraying water in a wash cycle and you open the door it will not stop. I was thinking it is the latch/actuator that is not triggering?Al

Dishwasher sometimes won't start when we push the button, latch seems fine. Could it be a new switch is needed? Thanks!
For model number GLD4458R10CS

Hello Robert. Thank you for your question. We suggest testing the switch PartSelect Number PS1021382. If the dishwasher is not starting, there are some parts that you will need to check to see which one is causing the issue. You will need to check the door latch, the flood switch and the main electronic control board. We hope this helps. Thank you and have a great day.

If this part is bad, can it cause dishwasher to continue running with door open?
For model number GLD4600N10BB
PartSelect logo
Hello Paul, thank you for your question. Yes, if this part is bad it could cause the appliance to continue running when the door is open. It is a switch, so it sends a signal that the unit is locked so the appliance will run. If its stuck in that position, the unit will thing its closed even though its not. I hope this helps!

Dishwasher leaking from switch left side towards the front of the dishwasher. Inside there appears to be some type of float with a stem that goes down and activates a switch. The water is dripping from the stem that contacts the switch. I dont see the part on the parts list.
