Frank for Model Number GU1200XTLS2 "cancel" button and "crystal china" button blinking. Press "rinse only" button and now all three lights blinking. Press "cancel" and "rinse only" light goes out and "crystal china" and "cancel" stay blinking. Press any other buttons with no response. "cancel" and "crystal china" still blinking. Is it the control unit (P/N 8564543 or the control panel(P/N 8534833 with the buttons} that needs to be replaced?
Answer Frank, You most likely have a faulty keypad assembly, : "PROBLEM: WON’T RUN AND LED ABOVE KEY(S) IS BLINKING > Stuck key(s) or shorted circuit(s) in keypad. > Check keypad. 2. Shorted circuits or connections on the control that read the keys.> Check control." WP8534833. Thanks and Good Luck Read More... Answered by AppliancePartsPros.com | Tuesday, April 3, 2012
