Hello, I am another user also having this exact problem today.

- My dishwasher is model GDF620HMJ2ES
- My initial issue is that the start button does not initiate washing. Instead, about 3 seconds after pressing start I hear 3 two-tone beeps. The Est. Time Left counts down but the dishwasher does not run and the beeps are heard again every 90 seconds or so.
- I have tried the service check and all lights flash indicating an issue with door closure.
- There does not appear to be a mechanical issue with the door latch.

What should I try next to diagnose this problem? Please move me to another thread if needed since my model number is slightly different.

While the machine is in standby mode, simultaneously press and hold the cycle select and the start buttons for 5 seconds. This is error mode. The first 10 seconds of error mode the control will report the door status. LEDs solid = door closed, blinking = door open. After the 10 second door check is error mode. If the Start, Heated Dry, Wash Boost or Clean LED is on there's an error. The Lock LED will always be on.

Remove power or unplug the machine and access the lower control board:

Restore power and check the status LED on the control board. Is it on, off, or blinking a pattern.

Hello, thanks for your quick response, for this new thread and for your clear instructions.

I have accessed the control board and performed the following tests:

Washer in normal mode but not running - LED not lit
Washer in normal mode and I press start - LED not lit, (3 2-tone beeps are still heard)
Washer in service check mode - LED not lit

Thanks for your continued help!

If the LED is not lit in any of these modes, does it mean that the control board needs to be replaced?

Yes, you nailed it!

Order the new control board and you will be back in business!
