Could be a faulty water temperature sensor, it won't close the cycle without the water reaching the proper temp.

I'm presently looking at a possible faulty water trmperature sensor. Thanks for the suggestion. I read somewhere on line that it should read 55 ohms with an ohm meter at room temperature.

Running the machine through the diagnostic mode did not provide any usuable information.

I will update findings

Thanks for the heads-up. I tested the input current with my Amprobe and found I got the correct value (1.5 to 2 amperes) when the drain pump or the circulator pump were running. When it was time for the heating element to function, I didn't read the normal 11 amperes. I now proved that the water is not heating during the wash cycle. Your were spot-on!

My next step to measure the voltage out of the control board, using a voltmeter. I sould measure 120 VAC on the RED wire when it is time for the water to heat during the wash cycle.

Getting a correct 120 VAC reading will prove that the relay in the control module is functioning and sending the required voltage to the heating element circuit. Unfortunately, there is also 2 sensors/switches in this loop, so further testing will be required to deterime which of the 3 components is actually defective.

No measured voltage will comform a defective control module. I will post updates.
