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.
When performing live voltage measurements, you must do the following:
■
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.
Electrical Supply:
(Under load) 60 Hz, 120 VAC
Supply Water Flow Rate:
To fill 2 qt (1.9 L) in 27 seconds, 120 psi maximum, 20 psi minimum.
Supply Water Temperature:
120°F (49°C) (Before starting a cycle, run water from sink faucet until hot.)
Water Charge:
1.3 gal. (4.8 L) first fill (approximate), 1.1 gal. (4.3 L) other fills

Fuse Service Check:
F1 = Small-triac load fuse
Check operation of loads during Service Diagnostics cycle.
■
If any of the triac loads work, F1 fuse is OK.
■
If all triac loads fail to work, F1 fuse could be open.
See "Fuse Resistance Check."
Fuse Resistance Check:
1.
Unplug dishwasher or disconnect power.

Meter Check of Loads and Fuses
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.

2.
Measure resistance of fuse F1.
NOTE: The fuse is on the bottom of the Control Board but can be checked
from the top side. See "Control Pinout" diagram.
If resistance is <3 Ω, fuse is OK.
■
If resistance is >3 Ω, replace control.
■
What To Do If Fuse Open:
Inspect and check resistance of all loads on fuse. If any loads are open,
shorted, or have evidence of overheating or pinched wires, replace loads
and/or repair wires.
