Door will not
open
Thermoactuator
Check to see if thermoactuator and its mechanism are stuck or
binding and not allowing the door lock motor 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 thermoactuators do not receive voltage at the
correct times, change the PCB relay board. If the timing and voltage
are correct, replace the thermoactuator.
Door Locking Motor
Check the door lock motor. Make sure the motor is not stuck or in a
bind. If motor does not move freely, replace locking motor.
Door Rod
Check to see that door rod from locking motor to lock assy is long
enough to allow lock assy to disengage. If not, adjust rod.
No hot water
in detergent
dispenser
Water Valve Coil
Check coil continuity at terminals and replace if no continuity. 24 V
power only on for 20 second in wash bath.
Water Inlet
Check water inlet screens for blockage and clean screens if
necessary.
Water Check to ensure that water is turned on and operating.
P-20 Wire Harness Check black & white harness.
Hot water
does not
enter tub in
wash
Water Valve Coil
Check coil continuity at terminals and replace if no continuity. Check
for 24 V power from main relay PCB.
Water Inlet Check water inlet screens for blockage and clean if necessary.
Water Check to ensure that water is turned on and operating.
Black or white wire at
controller and main relay
PCB
Check black and white wire at Molex plug on main PCB controller
P21 connection and at PCB relay board P20 connection.
Pressure Switch
Check pressure switch continuity between terminal contacts. If no
continuity, check pressure switch hose for obstruction. If the hose is
okay then change pressure switch.
No cold water
to tub in
wash
Water Valve Coil
Check coil continuity at terminals and replace if no continuity. Check
for 24 V power from main relay PCB.
Water Inlet Screens Check water inlet screens for blockage and clean if necessary.
Water Check to ensure that water is turned on and operating.
Black or white wire at
controller and main relay
PCB
Check black and white wire at Molex plug on main PCB controller
P21 connection and at PCB relay board P20 connection.
Pressure Switch
Check pressure switch continuity between terminal contacts. If no
continuity, check pressure switch hose for obstruction. If the hose is
okay then 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 there is power to the valve
but drain valve does not close, replace drain valve and motor.
• Power to the drain valve. If no power to drain valve, check
(brn/yel) wire at PCB relay board. If there is no power on the
(brn/yel) wire when the washer is in a wash cycle, replace relay
board.
Black or white wire at
controller and main relay
PCB
Check black and white wire at Molex plug on main PCB controller
P21 connection and at PCB relay board P20 connection.
