Customer Questions and Answers for Control Board by Whirlpool

Richard, You will want to check your soil sensing switch 8542575 to make sure that it is good. If good then you will need to replace the control board WP8564547. To check the switch you would do a continuity test. The switch will read normally open unless there is significant soils in the pump. If the switch reads closed then check to make sure that there is not a lot of build up in the pump and if this checks ok then replace the switch. If the switch checks open then replace the control board.
