Woodmore for Model Number KUDS30CXWH1 Dishwasher "locked" light comes on randomly and cannot be turned off by pressing for 3 seconds. Solution has been to take out 4 screws for control panel and disconnect 2 connects from wire harnesses. One harness goes to control panel circuit board behind buttons/lights that show functions selected. Other harness goes to small display board on right side of control panel that shows wash/rinse/dry/clean progress. Disconnecting cables had been clearing up problems--for weeks at a time--but now variojus new problems arise daily or even immediately after a wash cycle, all of which lock out functionality and operation of dishwasher. One problem is 'Cancel' light stays lit and will not clear. Or, another is 'Normal Wash' lights and stays lit, but does not activate dishwasher--plus, the 'Heat Dry' button will not activate at the same time. The problem of not being able to activate the dishwasher is more frequent (now daily or right away after using it for a cycle), and more buttons are "involved" in the flakey behavior. Is the problem the control panel (expensive) or the electronic control board (even more expensive)? It might be cost effective to replace oneo the other. However, it may be cheaper to replace the dishwasher with a new one than buy a control panel AND a control board.
Answer Hello Woodmore. Based on the information you provided, it sounds like the control panel WPW10500164 is bad and will need to be replaced on the unit. Read More... Answered by AppliancePartsPros.com | Wednesday, July 22, 2015
