After filling with water on any cycle, the main pump never starts. The pump circuit receives 12VAC during fill, 8.9VAC during wash, and 5VAC when the door is opened! Does this indicate a bad control board?
Answer Hello J.L.,
This sounds like the control board 154776601 has malfunctioned. If unplugging the unit for 10 minutes doesn't reset the board to factory default and correct the units' behavior, the board will require replacement. Be aware that if the polarity of the power supply isn't connected to the unit correctly, it will cause unpredictable issues and cause the electronics to fail.
I need to replace my control board on the dishwasher, Are there any special tools I need to complete the task?
Answer Hello Steve, No, you should be able to change the board without any issue. On some models, there are torx screws that need to be removed to access the control board.
