Mark for Model Number MDB5601awq My dishwasher won't start. This began when the door latch got broken. I installed a new latch, still no go. Only keypads that light are "heavy wash" and "auto clean". No other pads light. I inspected the latch. It looks ok. I pulled the control panel. Only thing I see is that the ribbon has become dark brown at the conductive lines just as the ribbon comes out of the keypad and the brown stops just as the conductive lines become wider. I pulled the circuit board - both sides look ok (no scorches). I tried to run the field service test. Nothing happened. Tried to run the manual test. Nothing again. Is it the control board?
Answer Hello Mark, This sounds like the control panel itself has failed. If the lights stay on constantly, this is an indication that the buttons corresponding to these lights are stuck. If this is the case, the control panel 6-919819 will require replacement. Will Not Start Or Program Control Board Check incoming voltage to Control Board. Membrane Switch Check for proper operation of Membrane Switch. See membrane readings on the Technical Sheet located behind toe panel. NOTE: Make sure the pin connectors are making proper contact with pins on the Control Board. If the voltage is correct into the Control Board, and the board will not activate, replace board.
