Troubleshooting
10. Fill Alarm Analysis
Symptom: The display reads “FILLXX”, the signal light illuminates and the buzzer alarms.
The computer did not receive an input from the respective water level circuit telling it that the
washer-extractor filled in the time programmed.
WHEN A
FILL STEP BEGINS,
DOES THE WATER STAY IN THE
MACHINE AS THE FILL VALVES
OPEN AND THE DRAIN VALVE(S)
CLOSE? NOTE: THERE ARE
TWO DRAIN VALVES,
EITHER OF THE VALVES COULD
BE CAUSING THIS.
NO
ARE
THE FILL VALVES
OPENING AND ALLOWING
WATER INTO THE
WASHER-EXTRACTOR AS
THE COMPUTER
INSTRUCTS THEM TO DO
SO?
YES
IS
THERE
VOLTAGE (220
VOLTS) AT THE
DRAIN VALVE(S)?
CHECK THE DRAIN VALVE
FOR BLOCKAGE. IF THE
VALVE ISN'T BLOCKED,
REPLACE IT.
CHECK THE 1 AMP DN FUSE
ON THE FUSEBOARD.
REPLACE IT IF NEEDED.
NO
YES
REFER TO THE "NO FILL
ANALYSIS" FLOWCHART
AT POINT A.
NO
TEST ALL
FILL STEPS TO HIGH
LEVEL (E.G., CHXXXX [COLD FILL
TO HIGH LEVEL], HHXXXX [HOT
FILL TO HIGH LEVEL] AND
WHXXXX [WARM FILL TO HIGH
LEVEL]). ARE THE FILL LEVELS
BEING REACHED IN A TIMELY
MANNER (I.E., 5 MINUTES)? ALL OF
THESE STEPS SHOULD FILL
EASILY WITHIN
5 MINUTES.
CHECK FOR ANY BLOCKAGES IN THE
LINES (E.G., THE FILTER SCREENS OR
THE WATER VALVES) THAT MAY BE
RESTRICTING THE WATER FLOW.
NO
YES
TEST THE WATER LEVEL SWITCH AS FOLLOWS.
REPLACE THE WATER LEVEL SWITCH, AIR TRAP
AND/OR TUBING AS NEEDED.
A. CHECK THE AIR TRAP TUBING FOR LEAKS
AND/OR BLOCKAGE.
B. CHECK THE WATER LEVEL SWITCH WITH A
CONTINUITY TEST OR WITH AN OHMS TEST AT THE
FOLLOWING TERMINALS:
11 AND 12 (FOR LOW LEVEL)
21 AND 22 (FOR MEDIUM LEVEL)
31 AND 32 (FOR HIGH LEVEL)
THIS SHOULD BE A CLOSED CIRCUIT AT ALL THREE
POINTS THAT OPENS WITH AIR PRESSURE TO THE
SWITCH. BLOW INTO THE SWITCH TO PROVIDE AIR
PRESSURE.
NOTE: OPENING THE SWITCH WILL LIGHT THE LED
INPUT LEVEL INDICATORS ON THE DISPLAY.
