Hello,
I have a similar problem in my GE dishwasher.
Model - GDT545PSJ5SS
The dishwasher keeps beeping 3 times every 10 seconds or so. I tried everything that is listed on this forum but no avail. If i try and press "Select Cycle" and "Start" button together for 5 seconds to see if the door latch is a problem then all LEDs are flashing. No matter I close or open the door while pressing these buttons together.
I tried to open the control board to see what the status light shows there, the LED on control board is blinking twice every few seconds. Don't know if the control board is bad or the door latch.
Any help is greatly appreciated.
Thanks in advance!

You will need to ohm test the door latch switch to determine if its bad. But 9 times out of 10 the problem is the machine control board.

Here's the machine control board for your model: WD21X24901 Machine Control

Here's the door latch switch for your model:
WD21X10490 Latch Switch


Follow the directions here:

Door closed: 0 ohms.
Door open: infinite ohms.

Let us know what you find. Make sure you disconnect power to the dishwasher before ohm testing.

Thank you Jake for the response. I ordered the door latch, swapped it out and still same issue. Now on to the control board. Will try swapping when it arrives. Keeping fingers crossed.

Yes, the new machine control board should fix it.

Let us know how it goes.
