The washer does not start. The start button light keeps blinking green.

I pressed the Normal Wash, Hi Temp, cycled the Heated Dry button 3 to 5 times. The washer started. Apparently the sequence resets the washer.

When the clean light is blinking the dishwasher control board is sensing a fault in the water heater. Take off the dishwasher toe-kick panel to get the diagnostic sheet and run the diagnostic cycle. This will clear the error. If it returns then you have a heater fault. Check the heater for any bubbling or arcs. Repair or replace it if necessary. Also, check the controller in the front panel for any scorching or heat stains. You may have a intermittent contact there. Hope this helps,
