How to Troubleshoot & Replace Ge AP7012649 / WH04X29448 Thermistor

In doing a little research, I found that two components would cause the two issues. The thermistor and the water inlet valve. I ordered, and in just several days they were on my doorstep. I watched a video, and in less than thirty minutes- the temperature of the water was correct and the flow and fill was back to what we had had. 

Thermistor was the likely suspect. Then the water valve solenoid, then the motherboard. I didn’t bother troubleshooting the water valve solenoid before ordering parts because disassembly of the washer is a bit of a pain and because the new valve assembly is quite inexpensive. I replaced both parts and the washer works as new. The valve assembly bench tested ok and the thermistor was bad. Keeping the old valve assembly just in case it’s needed in the future. 

Replacing the whole drain pump unit.
