Not being an experienced troubleshooter, but wanting to figure this out, I could really use some help.
All of a sudden my dishwasher won’t turn on. Normally when I press the power button I can then press one of the dishwasher cycle buttons (e.g., Heavy, Normal) and see and LED light come on to indicate my choice. When I close the door, the dishwasher turns on. Now when I press the power button and press one of the dishwasher cycle buttons, no LED light comes on. When I close the door, the dishwasher does not start.
I confirmed that power is getting to the dishwasher. I then removed the front panel of the dishwasher and tested continuity on the power button. There are four "blades" coming out of the switch that connect to the wire harness. When I press the power button I measured continuity between the first and second blade, but no other combinations. The two wires connected to these blades are the black wire (the power) and a black/gray wire that goes to the control panel. Another wire is the white neutral wire and the fourth is two red/white wires (one that goes to the door latch switch). Based on this simple test I think the power switch is working. Or am I wrong?
I’m wondering if the control panel is the problem, but I don’t how to test it. Does anyone know how to confirm if it needs to be replaced?
Thanks for any help that can be provided.
