The symptom was that none of the dishwashers light came on – it was totally dead
With this repair the important thing was making sure I was replacing the right part. I also tested parts in order to avoid disassembling more than I needed. I checked the following:
1. Circuit breaker
2. Electricity was getting to the connection box underneath the dishwasher. (Require removing panels between DW door and floor).
3. Next I disassembled the DW inner door and checked the switch. Power was getting to the switch. When depressed, power was go on both sides of switch.
4. I pulled out the electronic control assembly (ASM) and checked that power was getting to the ASM; it was. (Note: be careful about what you touch, there is 110 volts out in the open).
5. I pulled the ASM from the enclosing plastic box that surrounds it. I looked at the circuit board to trace where power went from the connector. Not surprisingly, it went through a fuse then to a transformer.
6. I checked the fuse two ways: I checked it hot: power was getting through the fuse. I also unplugged the power and checked the resistance. The fuse was good.
7. Set the Volt-Ohm meter back to 300 Volts AC range – do not risk putting 110 volts into the ohms setting.
8. 110 volts was getting to the primary side of the transformer. There was no voltage on the other side.
9. I unplugged the power and checked the resistance of the primary side of the transformer. It was “open” – meaning a wire is broken inside the transformer.
10. This confirms the problem in on the ASM board. If I knew the voltage on the secondary of the transformer and radio-shack had such a part I guess I could try unsoldering it and replacing it. But I didn’t know that and there were signs of water corrosion on the board so I replaced it.
11. PartsSelect made the look up easy. Delivery was fast. The DW now works again.
