Symptom Probable Cause Suggested Remedy
Door will
not open
Thermoactuator Check to see if thermoactuator(s) and/or its mechanism is
stuck or binding and not allowing the door lock gear motor
to open. Check to be sure that the locking thermoactuator
is not receiving 120VAC during the last 1 1/2 minutes of the
cycle. Also check to see that the unlocking thermoactuator
is receiving 120VAC during the last minute of the cycle. If
the thermoactuators do not receive voltage at the correct
times, change the timer. If the timing and voltage are cor-
rect, replace the thermoactuator.
Door Rod Check to see that door rod from solenoid to lock ass y is
long enough to allow lock ass y to disengage. If not, adjust
rod.
Door Locking So-
lenoid
Check that door lock solenoid is not stuck closed. If
stuck, replace solenoid.
Timer Make sure machine is in off position allowing Timer to
authorize door unlock.

Common Troubleshooting Solutions Common Troubleshooting Solutions
No hot
water in
detergent
dispenser
Water Valve Coil Check coil continuity at terminals and replace if no continu-
ity. 120 V power only on for 20 second in wash bath.
Water Inlet
Screens
Check water inlet screens for blockage and clean screens if
necessary.
Water Check to insure that water is turned on and operating.
Timer Advance to wash, check for voltage on red/org in from timer.
If not voltage, replace timer.
Hot water
does not
enter tub in
wash
Water Valve Coil Check coil continuity at terminals and replace if no continu-
ity. Check for 120 V power from main relay PCB
Water Inlet
Screens
Check water inlet screens for blockage and clean if neces-
sary screens
Water Check to insure that water is turned on and operating.
Timer Advance machine into wash cycle and check for 120VAC at
red/blue wire coming from timer.
Water Temp Selec-
tor Switch
Check switch for continuity between red/blue wire and red/
yellow wire when Hot is selected. If no continuity, change
switch.
Pressure Switch Check pressure switch continuity between terminals . If no
continuity, check pressure switch hose for obstruction. If

Water
comes in
but level
does not
rise
Drain Valve (open) Check these areas • Drain valve blockage • Drain valve mo-
tor and gear train. If power but drain valve does not close,
replace valve. • Power to the drain valve. If no power to
drain valve, check (brn/yel) circuit for power.
Water level
too high
Pressure Switch Check for blockage in pressure switch hose. Check for
pressure switch opening circuit across terminals . Replace
switch if contacts do not open.
Water
drains
