My son has a GE GDF520PGJ6WW dishwasher. The green light on the control board flashes too fast to count but I'm guessing it's blinking 7+ times second. I've read in other posts that I'll need to check voltage on this board. I have seen that I'd be looking for 13.5v for these connectors.
With this dishwasher, should I be checking this on the control board at the same points referred to previously - at J722 pins 2 and 5 and also at pins 1 and 2 on UI?
I don't see this dishwasher referred to previously but am hoping tat it is similar to others covered.

Thanks,

David

Hi David,

Per your model number, yours uses the square board: WD21X25732

So on the square board the flashing light means that machine control board is working and the problem would be the UI Board.

With this dishwasher, should I be checking this on the control board at the same points referred to previously - at J722 pins 2 and 5 and also at pins 1 and 2 on UI?

On this model the service manual does not say which pins power the UI Board.

Here's the UI(user interface) Board for your model:

When you click the UI Board part link you will see a video of how to replace it.

"NOTE--->When replacing UI control boards, the new UI Board MUST be configured as per the instructions included with the replacement. If the personality is not set by using the 4 jumpers, the buttons, LED’s or cycles will not function properly".

Let us know how it goes after you replace it.
