4. WATER RUNS CONTINUOUSLY INTO THE WASHER-EXTRACTOR
(Either when the machine is in cycle or not)
NO
3
TURN THE MAIN
POWER TO THE
MACHINE OFF.
DOES THE WATER
SHUT OFF?
THIS IS AN ELECTRICAL ISSUE.
DOES THE CORRESPONDING
LIGHT ON THE FUSEBOARD STAY
ON CONTINUOUSLY AFTER THE
DOOR IS CLOSED AND THE ACH
HAS BEEN ENERGIZED (E.G., IF
THE COLD SPRAY VALVE IS IN
QUESTION, IS THE CS LIGHT
STAYING ON)?
YES
THIS IS A MECHANICAL ISSUE.
REPLACE OR REPAIR THE
MECHANICAL PARTS OF THE
VALVE.
CHECK FOR MISWIRING AT THE
FUSEBOARD OR FOR A SHORT
ON THE WIRE THAT
ENERGIZES THE RESPECTIVE
VALVE (E.G., IF YV1 STAYS
ENERGIZED BUT THE COLD
FILL LIGHT ISN'T LIT ON THE
FUSEBOARD, CHECK THE
WIRING BETWEEN J5-1-2 AND
J15-1-1).
NO
Note: This information applies to the four main fill valves as well as the 4-way supply valves.
The first task in this process is to determine which valve is staying on. If it is one of the four
main valves (i.e., hot spray, hot fill, cold spray or cold fill), this may be done by individually
shutting off the water supply to each valve. If it is a supply valve that is staying open, find
the location in the dry supply box where the water is flushing into and follow the hose back
to the solenoid. Once the valve has been identified, proceed as follows:
MAKE SURE THAT THE MAIN POWER
TO THE MACHINE HAS BEEN TURNED
OFF. REMOVE THE WIRES BETWEEN J4
AND J5 ON THE INTERFACE BOARD.
PLACE A JUMPER BETWEEN THE TWO
WIRES. DISCONNECT THE RIBBON
CABLE BETWEEN THE COMPUTER AND
THE FUSEBOARD. TURN ON THE
MACHINE'S MAIN POWER. DOES THE
RESPECTIVE LIGHT ON THE
FUSEBOARD COME ON IMMEDIATELY?
YES
CHECK THE RIBBON CABLE
BETWEEN THE COMPUTER AND
THE FUSEBOARD. REPLACE THE
RIBBON CABLE IF NEEDED. IF
THE RIBBON CABLE IS OKAY,
REPLACE THE COMPUTER.
YES
NO
THERE IS A POSSIBILITY THAT THE
FUSEBOARD IS CONTAMINATED. TRY
CLEANING IT. IF THE TEST MENTIONED
IN THE PREVIOUS STEP IS STILL
UNSUCCESSFUL, REPLACE THE
FUSEBOARD.
