FAILURE 80: TIME IS OUT FOR DISPENSING LIQUID DETERGENTS
Failure 80 occurs when the On Hold Signal of the Liquid Supply Central Dispensing System stays high for more than 1 hour. At Input 16
of the washer computer, the Liquid Supply Central Dispensing System sends a "High" signal that pauses the washer during the Wash
Sequence for adding Liquid Supplies. The pause will continue until the Liquid Supply Central Dispensing System has pumped its chemical
supplies into the washer.
When the On Hold signal is "LOW" the wash program is NOT put On Hold.
When the On Hold signal is "HIGH" the wash program is put On Hold.
In normal operation the On Hold signal of the Liquid Supply Central Dispensing System must not stay high for more then 1 hour, otherwise
the washer will not complete the active wash cycle.
DIAGNOSE:
1. Check if the Central Soap Dispensing System operates
correctly.
2. Check if the wiring of the input signal "On Hold" is damaged.
3. Check the washer computer.
(Inputs can be checked one by one in the Service Menu)
FAILURE 81: NO REHEAT
Traceability only. Failure 81 occurs when the heating is not restarted (at the Wash Sequence) when the temperature of the wash water is
below its normal programmed value. When the temperature drops below the predefined temperature limit of a hygienic wash cycle, the wash
cycle cannot be validated for hygienic reasons because the wash process has not followed the standards of the wash program in execution.
This means that the laundry load must be washed again after repairing the problem with the heating system.
DIAGNOSE:
Check Diagnostics Failure 13: Heating Failure, and Failure 14: Heating Time Failure
FAILURE 82: NO REFILL
Traceability only. Failure 82 occurs when the water filling is not restarted (at the Wash Sequence) when the level of the wash water is below
its normal programmed value. When the water level drops below the predefined water level limit of a hygienic wash cycle, the wash cycle can
not be validated for hygienic reasons as the wash process has not followed the standards of the wash program in execution. This means that
the laundry load must be washed again after repairing the problem with the water fill system.
DIAGNOSE:
Check Diagnostics Failure 11: Fill Failure
FAILURE 83: CYCLE FAIL
Traceability only. Failure 83 occurs when the wash cycle can not be validated for hygienic reasons as the wash process has not followed the
standards of the wash program in execution. This means that the laundry load must be washed again after repairing the problem. The Error
message is only for information purposes and at the end of the wash cycle the operator will get a signal the wash cycle must be repeated.
DIAGNOSE:
See Extra Error message that shows the cause of the failure.
FAILURE 85: RTC LOW BATTERY
Failure 85 occurs when there is no battery available at the real time clock, or if the power of the battery is too small to make the real time
clock run correctly.
DIAGNOSE:
1. Check if the battery is still ok.
