Common Troubleshooting Solutions
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 showing a dollar
amount.
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 1.5 amp (T-1200. uses 2.5amp) breaker or fuse for
continuity. If no continuity, replace breaker or fuse.
Control Trans-
former
Check voltage output from control transformer for 120VAC.
If voltage is incorrect, 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 Relay PCB Check all wire connections for sure contact.
Check Door Sole-
noid
Check that 120 v power is at solenoid after start button is
pushed.
Door does
not lock
Check display for
fault code
Does F1 show on the front of display. If yes follow tests
described in fault code section.
Door locking sole-
noid
Check to insure that solenoid is receiving 120VAC from main
relay PCB. If it is, replace solenoid.
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 solenoid to
open. Check to be sure that the locking thermoactuator is
not receiving 120VAC during the last 1 1/2 minutes of the
cycle. Also check to see that the unlocking thermoactuator
is receiving 120VAC during the last minute of the cycle. If
the thermoactuators do not receive voltage at the correct
times, change the timer. If the timing and voltage are cor-
rect, 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 Lock Solenoid Check that door lock solenoid is not stuck closed. If stuck, replace
solenoid.
No hot water
in detergent
dispenser
Water Valve Coil Check coil continuity at terminals and replace if no continuity. 120
V power only on for 20 second in wash bath.
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.
