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.
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.
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.
Check coil continuity at terminals and replace if no continuity. 24 V
power only on for 20 second in wash bath.
Check water inlet screens for blockage and clean screens if
necessary.
Check to ensure that water is turned on and operating.
Check black & white harness.
Check coil continuity at terminals and replace if no continuity. Check
for 24 V power from main relay PCB.
Check water inlet screens for blockage and clean if necessary.
Check to ensure that water is turned on and operating.
Check black and white wire at Molex plug on main PCB controller
P21 connection and at PCB relay board P20 connection.
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.
Check coil continuity at terminals and replace if no continuity. Check
for 24 V power from main relay PCB.
Check water inlet screens for blockage and clean if necessary.
Check to ensure that water is turned on and operating.
Check black and white wire at Molex plug on main PCB controller
P21 connection and at PCB relay board P20 connection.
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.
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.
Check black and white wire at Molex plug on main PCB controller
P21 connection and at PCB relay board P20 connection.
