WARNING
Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
DANGER
Electrical Shock Hazard
Only authorized technicians should perform diagnostic
voltage measurements.
After performing voltage measurements, disconnect
power before servicing.
Failure to follow these instructions can result in death
or electrical shock.

NOTE: This sheet contains important Technical Service Data.
When performing live voltage measurements, you must do the following:
Voltage Measurement Safety Information
Verify the controls are in the off position so that the appliance does not start when energized.
Allow enough space to perform the voltage measurements without obstructions.
Keep other people a safe distance away from the appliance to prevent potential injury.
Always use the proper testing equipment.
After voltage measurements, always disconnect power before servicing.

Fuse Service and Diagnostic Checks:
For wash/drain motors fuse and triac load fuse.
Verify harness connections to all loads and control are made.
Check stored failure code and/or operation of loads during Service Diagnostics Cycle.
Triac Fuse Diagnostics:
Triac loads; Dispenser, Diverter Motor, Fill Valve, Lower Spray Arm (some models)
If any of the triac loads work, then the triac fuse is OK. Diagnose and repair non-working triac loads.
If all triac loads fail to operate, triac fuse may be open. Check the fuse and replace control if fuse is open. Inspect and check resistances of all loads on fuse.
If any loads are open, shorted, or show evidence of overheating or pinched wires, replace loads and/or repair wires.
Wash/Drain Motor Fuse Diagnostics
If both the wash and drain motors fail to operate, motor fuse may be open. Check the fuse and replace control if fuse is open. Inspect and check resistances
of both motor loads. If either motor is open, shorted, or shows evidence of overheating or pinched wires, replace loads and/or repair wires.
If only wash or drain motor operates, fuse is OK. Use meter to measure non-operational motor’s three phase resistances.
If a phase is open (> 1,000 W) or unequal to the others, motor is bad. Replace motor.
If all phases are equal and within range (see wash/drain circuit), use meter to verify wiring harness continuity (< 3 W) from control connection to motor phase.
