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 solenoid to open. Check
to be sure that red light on Input/Output PCB for locking thermo-
actuator #2 is not illuminated and that Input/Output PCB is not
sending 120VAC power to the locking thermoactuator during the
last 70
seconds of the cycle. Check to be sure that red light on Input/Out-
put PCB for unlocking thermoactuator #1 is illuminated and that
Input/Output PCB is sending 120VAC to the unlocking thermoac-
tuator during the last 30 seconds of the cycle.
Door Lock Solenoid Check that door lock solenoid is not stuck closed. Check to be
sure that Input/Output PCB is not sending 120VAC power to door
locking solenoid. Be sure that red light on Input/Output PCB for
door locking solenoid #3 is not illuminated. If door lock solenoid is
receiving 120VAC, check CPU, Ribbon Cable and Input/Output PCB
above.
Input/Output Board Check red door lock solenoid light #3 is on input/output board. If
illuminated, remove power to washer for 2 minutes to reset CPU
board. Reapply power to washer and check the door lock solenoid
light #3. If no light, okay. If red light is still on, check the CPU
board as described above under “Door does not lock”. If CPU
tests okay, change Ribbon Cables between CPU and input/output
board. If red door lock solenoid output light on input/output board
is illuminated, check that 120VAC is going from the input/output
board to the door locking solenoid. If voltage, replace I/O PCB.

not advance
in the cycle
Water Valves Check to insure that water valves are operating. If not, check to
be sure that red light on Input/Output PCB for water valves is il-
luminated #5,6,7,8 and that input/output board is sending 120VAC
to the water valve. If 120VAC, change water valve. If no voltage
check Input/Output PCB.
Drain Valve Check to insure that drain valve is closing. If not, check for
120VAC to drain valve from Input/Output PCB red light # 4. If
120VAC, change or clean drain valve. If no voltage, check CPU
board, Ribbon Cable and I/O PCB.
Fill Hose Screens
and 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 low or high position to close the
circuit to the Input/Output board. Either the green low level or
high level light on the input/output board must be lighted. Check
pressure switch continuity between terminals #31 & #22 for low
level and #31 and #32 for high level.
