Following up to my question above...
Yes, I am getting 120 V AC to the thermostat.
The heater measures about 13.5 ohms. I confirmed that it does heat during the dry cycle by opening the door and measuring with a digital thermometer. Touching directly to the element gave a reading over 200 F.
I ended up replacing the thermostat (even though I think the old part was OK) and it didn't fix the issue.
Today I ran the high temp cycle and placed the digital thermometer touching next to where the thermostat is mounted to see how hot it got and it only reached about 110 F. I believe the thermostat needs to hit about 124 F to close.
Still confused. Any other suggestions?
ANSWER Hello Mike. If the heater and the thermostat are working properly, and the water is hot at the sink before starting the cycle, then the timer 154412901 may be bad and will need to be replaced. Hope this helps.
