Symptom Probable Cause Suggested Remedy
Hot water
does not
enter the tub
(cont.)
CPU Board, Ribbon
Cable, Input/Output
PCB (cont.)
CPU light. If on solid, CPU okay. If still flashing or not on, replace
CPU board. If CPU tests okay, change Ribbon Cables between CPU
and Input/Output PCB. If red hot tub output light #5 on Input/
Output PCB is illuminated, check to insure that 120VAC is go-
ing from the Input/Output PCB to the water valve. If no voltage,
replace I/O PCB.
Cold water
does not en-
ter the tub
Water Valves Check to insure that water valve is operating. If not, check for
120VAC to water valve from Input/Output PCB. If 120VAC, change
water valve. If no voltage check Input/Output PCB.
Fill Hose Screens
Water Valve Screens
Check all screens for obstructions and clean.
Water
Check to insure that water is turned on and operating
.
Pressure Switch
Hose
Check hose for holes. Be sure the inlet end of the large part of the
hose is lower than the rest of the hose and is free of debris.
Pressure Switch Pressure switch must be in the empty position to close the circuit
to the Input/Output PCB. The green empty led tub empty #14
on the Input/Output PCB must be on. Check pressure switch for
continuity across terminals #31 & #22 indicating pressure switch
has reset to empty.
CPU board, Ribbon
Cable, Input/Output
PCB
Check Input/Output PCB for illuminated red or Input/Output PCB
water valve output light. If no red output light #8 illuminated,
check single red light on CPU board. Single red light should be illu-
minated. If light is flashing or not on, remove power from washer
for 2 minutes to reset board. Reapply power to washer and check
red CPU light. If on solid, CPU okay. If still flashing or not on,
replace CPU board. If CPU tests okay, change Ribbon Cables
between CPU and Input/Output PCB. (Check with factory for lat-
est testing procedures for I/O PCB) If red water valve output light
on input/output board is illuminated, check to insure that 120VAC
is going from the Input/Output PCB to the water valve. If no volt-
age, replace I/O PCB.
No hot water
in detergent
dispenser
Water Valves Check to insure that water valve is operating. If not, check for
120VAC to water valve from Input/Output PCB. If 120VAC, change
water valve. If no voltage check Input/Output PCB.
Fill Hose Screens
Water Valve Screens
Check all screens for obstructions and clean.
Water

CPU Board, Ribbon
Cable, Input/Output
PCB
Check Input/Output PCB for illuminated red or Input/Output PCB
water valve output light. If no red output light #8 illuminated,
check single red light on CPU board. Single red light should be
illuminated. If light is flashing or not on, remove power from
washer for 2 minutes to reset board. Reapply power to washer
and check red CPU light. If on solid, CPU okay. If still flashing
or not on, replace CPU board. If CPU tests okay, change Ribbon
Cables between CPU and Input/Output PCB. If red output light #5
on input/output PCB is illuminated, check to insure that 120VAC is
going from the Input/Output PCB to the water valve. If no volt-
age, replace I/O PCB.
