Symptom Probable Cause Suggested Remedy
Machine does
not start
Power Supply Check these areas: Circuit breakers, Voltage, Power leads, Power
connections
Start Button Check for green start button, light on Input/Output PCB # 6 when
button is depressed. If no light check membrane switch assembly
and ribbon cable
Control Breaker or
Fuse
Check 1.5 amp (T-1200 uses 2.5amp) breaker or fuse for continu-
ity. If no continuity, replace breaker or fuse.
Door Switch Check for continuity through door switches when door is closed
and locked. Check Input/Output PCB for green door closed light #
4 and green door locked light #3 showing that door switches
are functioning correctly. If no continuity or green light on when
door closed and start button pushed, check door switch and wir-
ing assembly
Control Transformer Check voltage output from control transformer for 120VAC. If volt-
age is incorrect, replace transformer.
Check PCB Board Check all wire connections for sure contacts.
CPU Board Single red light should be illuminated. If light is flashing or not on,
remove power from washer for 2 minutes to reset board. Reapply
power to washer and check red light. If on solid, all okay. If still
flashing or not on, replace CPU board.
Check Relay PCB Check all wire connections for sure contact.
Check Door Solenoid Check that 120 VAC power is at solenoid after start button is
pushed.
Machine
starts then
stops
Door Switch Ass’y I/O PCB must have green input lights, DOOR
LOCK 3, DOOR CLOSED #4, TUB EMPTY #14,
RUN KEY #2. START #6 WILL BE ON WHEN
pushed. If these are not on, check door switches
and wiring to and from control panel.
Door Locking
Gear Motor
Check I/O PCB red output light DOOR SOL. #3 is on. 120 VAC to
gear motor? Is linkage rod adjusted properly?
Door does
not lock
CPU Board, Ribbon
Cable or Input/Out-
put Board
Check Input/Output PCB for green input door closed light #4 and
green input door locked light . Check #3 single red light on CPU .
Single red light should be illuminated. If light is flashing or not on,
remove power from washer for 2 minutes to reset CPU. Reap-
ply power to washer and check red CPU light. If on solid, CPU
okay. If still flashing or not on, replace CPU board. If CPU tests
okay, change Ribbon Cables between CPU and Input/Output PCB.
(Check with factory for latest testing procedures for I/O PCB) If no
voltage, replace I/O PCB.
Door Locking
Gear Motor
Check to insure that solenoid is receiving 120 VAC from Input/Out-
put PCB. Is I/O PCB red output light #3 on? If 120 VAC and output
light is lit, replace gear motor.
Door Switch Check for continuity through door latch switch when door closed.
If no continuity, adjust or replace door switch.
Door will not
open
Door Rod Check to see if the mechanism is stuck or binding and not allow-
ing the door lock motor to open.
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 red light on Input/Output PCB for locking
thermoactuator #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/Output PCB for unlocking thermoactuator #1 is illuminated
and that Input/Output PCB is sending 120VAC to the unlocking
thermoactuator during the last 30 seconds of the cycle.
Door Lock gear mo-
tor
Check that door lock gear motor is not stuck closed. Check to be
sure that Input/Output PCB is not sending 120VAC power to door
locking gear motor. Be sure that red light on Input/Output PCB for
door locking gear motor #3 is not illuminated. If door lock gear
motor is receiving 120VAC, check CPU, Ribbon Cable and Input/
Output PCB above.
Input/Output Board Check red door lock gear motor 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 gear
motor 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 gear motor output light on input/output
board is illuminated, check that 120VAC is going from the input/
output board to the door locking gear motor. If voltage, replace
I/O PCB.
Machine
starts but will
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.
