Fuse Service Check:
F601 = Small triac load fuse
F600 = Wash pump motor fuse
Check operation of loads during Service Diagnostics cycle.
 If any of the triac loads work (ll, dispenser, drain), F601 fuse is OK.
 If all triac loads fail to work, F601 fuse could be open.
 If wash pump motor runs, F600 is OK.
 If wash pump motor does not run, F600 fuse could be open. If either
fuse could be open, See the “Fuse Resistance Check” section.
Fuse Resistance Check:
Unplug dishwasher or disconnect power.
Measure resistance of fuses F600 and F601.
a. Disconnect wash pump motor wiring jumper P5 from the control board.
b. Using a resistance meter, measure the resistance between
control board connection pins P5-2 and P6-3. See “Control
Pinout” diagram.
 If resistance is < 3 Ω, both fuses are OK.
 If resistance is > 3 Ω, replace control.
What To Do If Fuse Open:
Inspect and check resistance of all loads on fuses. If any loads are open,
shorted, or have evidence of overheating or pinched wires, replace loads
and/or repair wires.

Metering of Triac Loads
Load must be connected for triac to operate correctly. Meter checks are best made at the control. See illustration below and “Dishwasher Strip
Circuits.”
Dishwasher Strip Circuits
The following individual circuits are for use in diagnoses. Do not continue with the diagnosis of the appliance if a fuse has blown, a circuit breaker is
tripped, or if there is less than a 120 V power supply at the wall outlet.
 Unplug dishwasher or disconnect power.
 Perform resistance checks. To check resistance of a component, disconnect harness leads rst.
