GE dishwasher wouldn't start or show lights on the control panel. Seth M. • Portland , OR • December 18, 2022
I started with Google searches for the problem, using the dishwasher model number to narrow down the number of results. When I found several posts in the forum on AppliancePartsPros.com from other people having the same problem with the same dishwasher, as well as solutions that involved replacing the control board, I decided to start with that.
The repair was very easy, especially with the help of clear and well-paced videos showing exactly what to do and what to look for. I was able to...

815 error code dishwasher thinks door is ajar. Cesar G. • Chicago , IL • July 24, 2020
Indicator light would blink three times, make a sound, but the dishwasher would not run. After making sure there were no obstructions, no problems with seals, filters, and latch clean, I cut the power off and back on. The Dishwasher worked for a few more times. After that, cutting the power off and on no longer worked. I figured out what buttons to press and hold to find the error code (start/stop and cycle select), saw code 815, and then did a "hard reset" by pressing and holding other...

Three beeps when trying to start dishwasher Aaron F. • Chapel Hill , NC • April 10, 2020
Two weeks ago, my dishwasher would not run. It would beep three times when you pushed the start button: the same signal it gives when the door is open. I used the troubleshooting steps I found at applianceblog.com to do a hard reset. (Hold START and WASH TEMP for five seconds, close the door, and wait 3 minutes) After that, it worked for about one week. When it started having the same issue again, the hard reset did not work. I lowered the control board and could see that there were no lights....

Dead dishwasher Arthur H. • Kingwood , TX • June 26, 2023
My GE dishwasher (GDT605PMM0ES) had started going in and out of service but if I unplugged it and plugged it back in it would work a few more times. Then one day that old trick didn't work anymore. Looked at what might be the issue on the internet and most signs pointed to the configured service machine control board or the configured Ui board. I ordered both, not really which was bad, but started with the Ui board first because the service machine control board showed it was receiving...

Part Number: WD21X10519
The Flood Switch Assembly is an OEM part for GE dishwashers that is responsible for detecting water levels in the dishwasher's base, preventing potential flooding by shutting off the water intake if an overflow is detected. This helps in avoiding water damage to your home and ensuring the dishwasher operates normally.
Symptoms of a bad Flood Switch Assembly include:
- The dishwasher not filling with water
- Water not draining properly
- The dishwasher stops during a cycle
Causes of a bad flood switch assembly can vary from debris accumulation affecting the float's movement to electrical issues within the switch mechanism. Over time, wear and tear on the float or switch can lead to failures.
This OEM GE part can also be used on Hotpoint, RCA, and Kenmore/Sears appliances.

Removed two 1/4" head screws with nut driver to then remove float switch, unplugged float switch, plugged in new switch, reinstalled filter, etc. This is a 5 minut job!

My GE dishwasher control stopped functioning Stephen C. • Hillsboro , OR • September 16, 2023
The control went thru a month or so of erratic behavior; the display would come on and flash and beep without any input on my part. Then it died completely. I did a little research on the GE website and determined likely cause waa a defective user interface board. I found AppliancePartsPros.com and contacted their tech support, who directed me to check the output of the control board across 2 pins for 13.5v DC. I did this, and measured 13.8v, so control board was good. When I reconnected the...

No lights but did have power (GE dishwasher) Jeffery S. • Spicewood , TX • January 25, 2021
First I watched Youtubes and decided it was the lower control board, ordered it from Appliance Parts Pros, and got it within 2 days. Installed it and no change.

Genuine Ge part
By: Ge
Part Number: WD21X10261
The Interlock Switch is an OEM replacement part for GE electric and gas dryers. This safety component monitors the door closure, preventing operation if the door is not securely closed and latched. The switch measures 2 inches long and 1/2 inch wide.
Symptoms of a faulty interlock switch include:
- Dryer failing to start or running with the door open
- Timer display not illuminated when start button is pressed
- Inability to open the dryer door during operation
- Dryer suddenly stopping mid-cycle before fully drying clothes
Causes relate to the internal component contacting the door frame over 50,000 open/close cycles potentially exposing wiring to wear. Regular cleaning the external switch area prevents dust or lint buildup skewing performance.
This genuine GE switch is compatible with Hotpoint and RCA dryers as well.
Note: Can be used as a dishwasher door switch on specific models. Check your model number for the most accurate results.

Melted door switch. Christopher K. • Greeneville , TN • February 03, 2024
The full story:
Dishwasher stopped running mid-cycle. When I first began troubleshooting I tried manually advancing the timer knob, and the machine would run. That led me to believe that the actual timer assembly was bad, so I replaced it. The dishwasher ran fine for a day, and then the same problem came back. This time, however, I also had to push in on the door to get it to run. I looked around online, and someone suggested that the door latch wasn't closing tightly enough. I adjusted the...

Soap dispenser would not open during wash cycle Kyle C. • Tallahassee , FL • November 23, 2014
Tried CLR to remove hard water deposits. That did not help. Ordered new dispenser. The GE series that the detergent module fits in was a little difficult to open. Finally found a video explaining the whole door had to come off in order to open it up to replace the module. Works great now.

Soap dispenser door no longer opened during cycle Matthew S. • Omaha , NE • September 09, 2014
Process was a bit more complicated than the videos I had watched online. Had to remove both front panel and control panel to get to soap dispenser. Removed wires to soap dispenser and rinse aide dispenser. Removed wire "harness" around the top and right side of dispenser. Pried back the clips to allow dispenser to be pushed out. It was helpful to have another person to hold the door open at this point. Bent clips back and reinstalled everything. New part works great.
