Thank you very much for your really fast response.That download has lots of useful info.I was really surprised to see at the last page the specifications of the pumps.Heatpump:3 pole bldc.60vac;150hz;1200w thick film heater;80w motor.  drain pump3 pole bldc;54vac;55hz;2500-3500rpm.dispenser 165vdc;2.67k ohm coil.Those are important when measuring the power input to them.The diagram did not show where to measure the power for the display. So I ordered the control board which supplied the different control voltages.I keep my fingers crossed.If the problem is in the display board,then I have to wait longer.

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.
