Jim for Model Number SHX43C02UC/46 Bosch SHX43C02UC/46. Before starting the dishwasher, a pump running noise occurs as soon as the power button is pressed with door open. Will not stop unless power button is turned off. Drains and fills normally. Cycles normally and dishes are clean and hot. Problem only happens occasionally. Seems to resolve by leaving power off for a little while. Removal of door and kickplate shows no leaks or standing water, all electrical connections are secure. Spray arms, filters are clean. Could this be control board or something else?
Answer Jim, For this issue check for a possible stuck float switch on the unit. If this checks ok then the issue will most likely be a faulty main control board. Read More... Answered by AppliancePartsPros.com | Thursday, February 8, 2018
