I went back with a new control board located on the bottom right hand side where the Power cord is plugged into.Ehrn the circuit breaker was turned back on,the dishwasher started draining,I did not push any buttons,and the display was still not there.Ivthoughy I would push the stop button and change the cycle.Thr dw stopped,still no display.I could not start it again.Now I got the new magnetic latch,will replace it,hopefully the display may come back.zI am not sure how I lost the Display.I am going to start a new post to ask how to check the hall effect door switch.
