We purchased the dishwasher about three years ago. The dishwasher flashes constantly on normal wash, sometimes all of the lights will come on as well.We have to press the cancel button a few times and occasionally it will clear it and then you can run the dishwasher. We have replaced the board, replaced two switches, had a professional in, and still we cannot solve this issue. Please if someone can solve this mystery please help us.

Thanks

Here is your tech sheet.

I am assuming the board you replaced was the control board

It could be the keypad.
Try the below, if that does nothing then check it with a meter as per the tech sheet

RIBBON CABLE CLEANING
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
