Section 5 Service Procedures
To reduce the risk of electrical shock, fire, explosion, serious injury or death:
• Disconnect electrical power to the washer-extractor before servicing it.
• Close the gas shut-off valve to the washer-extractor (when applicable) before servicing it.
• Never start the washer-extractor with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer-extractor is properly grounded.

24. TEST CYCLE
Cycle 01 is a pre-programmed test cycle used to
check all functions of the machine. Refer to
Figure 2.
a. Start this cycle by pressing “0,” then “1,” then
“START.”
b. The display should show “CL01” with the LED
for “COLD FILL” and “COLD SPRAY”
illuminated at the left of the module front,
indicating that these water valves have been
turned on.
c. The “DRAIN CLOSED” LED should be lit.
The “FORWARD” and “REVERSE” LEDs
should alternate on and off.
d. The programming manual indicates which
LEDs should be lit for each step.
e. If only one LED on the fuse board is not lit:
(1) Check the fuse on the fuse board associated
with that LED.
(2) If the fuse is OK, check the J-1 ribbon cable
between the computer and the fuse board.
(3) If the fuse is blown, check the related valve
or relay for a shorted condition before
replacing the fuse.
(4) Use a similar procedure for any individual
function that does not work.
IMPORTANT: For proper protection when
replacing fuses, use replacement fuses with the same
type and rating.
If the display indicates a “DOOR” alarm:
a. The computer has detected an unlocked door.
b. Check the switch activator on the door lock
extension arm.
c. Check the door lock switch.
d. Check the input plug, J-2, on the computer
board. Refer to Figure 1.
e. Check for loose wires or bad connections
associated with the door lock switch.
If the display indicates a “WATER” alarm:
a. This display will usually appear following a
final spin step. This indicates that the computer
has not received a signal indicating that the
machine is empty. This means that the machine
may still contain water. The door remains
locked and keyboard will not respond. Check
the drain and for a faulty low level switch.
If the display indicates a “FILL” alarm:
a. The water level was not reached in the allotted
time.
b. Push “START” to add more time to the cycle.
c. Check for leaks in the air system between the
level switches and the water level air chamber.
d. Check for obstructions in the water level air
chamber or tubing.
e. Check for obstructions or low pressure in the
water supply system.
f. Check for a failed drain valve motor. Check for
leaks in the drain valve.
g. Check for a defective water level switch.
If the display indicates an “EMTY” (empty)
alarm:
a. The water level has not reached empty in the
allotted time.
b. Check for a slow drain.
c. Check for a defective water level switch.
d. Check for obstructions between the air system
and the pressure switch.
e. Check for loose connections in the water level
circuit.
NOTE: Sufficient time for filling and draining must
be allowed when programming the computer. If a
“FILL” or “EMPTY” alarm occurs in only one
program, edit that program and re-enter it into the
computer, making sure that enough time has been
allowed for fill and/or drain.
