Scott for Model Number Whirlpool GU1200XTLS2 My DW lost its mind. It will occasionally allow an Hi-Temp Scour / Air Dry / Hi-Temp Scour / Air Dry / Hi-Temp Scour reset and begin to act right, but then it will light up the Sani Rinse and Washing light and run doing something but nothing sensical. If I press the cancel button everything stops, but later on it randomly starts back up in that endless Sani Rinse mode. I disconnected and reseated all the connectors on the control board. Thought that fixed it but it fell right back into its insanity after running in the Normal wash mode for almost the whole cycle. Control Board? Thanks.
Answer Scott, You most likely have a faulty keypad assembly WP8534833. since you reset the control and the issue returned, start at the control panel/keypad assembly. display lights that are irratic, or illuminate on their own, indicate an issue in the pad itself, or the ribbon is shorted.
