Heater diagnosing
Test programs heat the water to 150ºF at ~ 2ºF / minute. To
run the entire test – when water circulates and the heater is on, measure the
incoming current to the dishwasher. If the current is ~ 11A, the heater is OK. If
the current is ~ 1.5 – 2A, the control or heater could be faulty.
At the control or heater, measure the voltage between the large
and a chassis ground or the dw neutral
wire). If the voltage is 120 VAC, the control is OK. If the voltage is 0, the heater
relay has failed – replace the control.

Failure Resolution
1. Turn water supply completely on and
adjust to proper water pressure.
2. Clean out water line and screen.
3. Check for leaks and drain water from
the base to disengage the float
switch. If water won't drain from
dishwasher tub, see Will Not Drain.
4. If voltage is not ≈ 120V, go to step 5.
