Heating element not working.
Troubleshot using Error and Service Modes.
No error codes were returned. Heating element did not heat up during Service Mode.
Checked heating element with ohm meter. Continuity and resistance (ohms) was within range (around 16.5 ohms…I didn’t take note of actual reading).
Checked voltage during Service Mode at the heating element using a volt meter. Never saw voltage at heating element.
Checked Flood Switch with ohm meter. It worked as expected.
Ordered and replaced the Control Board.
Still no heat.
Located the Thermal Cut Out (TCO) on the right underside of the tub about 12 inches from the front of the tub. It was tripped. Pushed the reset button on it and ran Service Mode again. Burnt my finger on the heating element. I was happy about that. :)
Dishwasher is working perfectly now.
According to all I read. If the TCO trips the Control Board should be replaced. So I don’t feel I replaced the Control Board needlessly.
