Symptom Probable Cause Suggested Remedy
Machine
does not
start
Power Supply Check these areas: Circuit breakers, Voltage, Power leads,
Power connections. Is front display LED display lit?
Door Switch Check for continuity through door switch when door is
closed. If no continuity, adjust or replace door switch.
Control Breaker or
Fuse
Check the 1.5 amp and 2.0 amp fuses (60 hz models) or
circuit breaker (50 hz models) for continuity. If no continuity,
replace fuse or breaker.
Control Trans-
former
Check voltage output from control transformer for 24 VAC
and 120VAC (50 hz models have 24 VAC only). If voltage is
incorrect, check for proper transformer tap connection or
replace transformer.
Check PCB board Check all wire connections for sure contacts.
Check wiring be-
tween PCB
Check data cable phone type connectors unplug and VFD
and replug with power removed.
Check Door Lock
Mechanism
Check that 120 VAC power (for 60 hz) or 24 VAC power (for
50 hz) is at door lock motor after start button is pressed.
Door does
not lock
Check display for
fault code
Follow tests described in fault code section.
Door locking
mechanism
Check to ensure that mechanism is receiving 120VAC for 60
Hz. models (or 24VAC for 50 Hz. models) from main relay
PCB. If it is receiving power but not functioning, then re-
place mechanism.
Door Switch Check for continuity through door latch switch when door
closed. If no continuity, adjust or replace door switch.
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 mechanism
to open. Check to be sure that the locking thermoactuator
is not receiving 24VAC during the last 1 1/2 minutes of the
cycle. Also check to see that the unlocking thermoactuator
is receiving 24VAC during the last minute of the cycle. If the
timing and voltage are correct, replace the thermoactuator.
Door will not
open
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 mecha-
nism
Check that door lock mechanism is not stuck closed. If stuck,
replace.
No hot water
in detergent
dispenser
Water Valve Coil Check coil continuity at terminals and replace if no continuity. 120
VAC power (60Hz) only on for 20 second in wash bath. (24 VAC
for 50 Hz models)
Water Inlet Check water inlet screens for blockage and clean screens if neces-
sary.
Water Check to insure that water is turned on and operating.
P-20 Wire Harness Check black & white harness.
Symptom Probable Cause Suggested Remedy
Hot water
does not
enter tub in
wash
Water Valve Coil Check coil continuity at terminals and replace if no continuity.
Check for 120 VAC power (60 Hz) from main relay PCB. (24 VAC
for 50 Hz models)
Water Inlet Check water inlet screens for blockage and clean if necessary
screens
Water Check to insure that water is turned on and operating.
Check Voltage If appropriate voltage is not present at the valve, refer to the wir-
ing diagram for your specific washer model. Check for voltage at
the P4 Connector on the Relay PCB. Check for LED indication that
the appropriate relay is activated.
Pressure Switch Check pressure switch continuity between terminals . If no con-
tinuity, check pressure switch hose for obstruction. If hose okay,
change pressure switch.
No cold wa-
ter to tub in
wash
Water Valve Coil Check coil continuity at terminals and replace if no continuity.
Water Inlet Screens Check water inlet screens for blockage and clean if necessary.
Water
Check to insure that water is turned on and operating.
Check Voltage If appropriate voltage is not present at the valve, refer to the wir-
ing diagram for your specific washer model. Check for voltage at
the P4 Connector on the Relay PCB. Check for LED indication that
the appropriate relay is activated.
Pressure Switch Check pressure switch continuity between terminal contacts. If
no continuity, check pressure switch hose for obstruction. If hose
okay, change pressure switch.
Water comes
in but level
does not rise
Drain Valve (open) Check these areas:
• Drain valve blockage
• Drain valve motor 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 cir-
cuit for power.
Check Voltage If appropriate voltage is not present at the valve, refer to the wir-
ing diagram for your specific washer model. Check for voltage at
the P4 Connector on the Relay PCB. Check for LED indication that
the appropriate relay is activated.
Water does

ment.

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
slowly
Drain System Check hoses and drain valve for blockage. Clean of inad-
equate size. if necessary. Check building drains for blockage
