FAILURE 57: DOOR LOCKED
MB90-140-180 machines only. Failure 57 occurs when the "Door Lock Switch" stays locked when the outer
door has been unlocked pneumatically and opened by hand. Purpose is to find out at the unload sequence if
"Door Lock Switch" is broken. (Normal Open Contact that stays closed)
DIAGNOSE:
1. Check the functioning of the
"DOOR LOCK SWITCH".
2. Check the mechanical functionality of the door
lock.
3. Check the continuity of the wiring.
4. Check the functionality of the
pneumatic lock system.
5. Check the input signal from the
"DOOR LOCK SWITCH".
ATTENTION !!!
!
YOU CAN STILL UNLOAD THE FABRICS FROM ALL COMPARTMENTS BY OVERRULING THE ERROR
MESSAGE BY PRESSING THE START BUTTON WHEN THE MESSAGE "CONTINUE >> START"
OCCURS
ASK FOR TECHNICAL ASSISTANCE FROM YOUR LOCAL DEALER TO SOLVE THE TECHNICAL
PROBLEM BEFORE STARTING A NEW WASH CYCLE
FAILURE 80: TIME OUT INPUT 16
Failure 80 occurs when the On Hold Signal of the Liquid Supply Central Dispensing System stays high for
more then 1 hour. At Input 16 of the wash computer, the Liquid Supply Central Dispensing System sends a
"High" signal that makes that the washing machine waits at the Wash Sequence to add Liquid Supply until
the Liquid Supply Central Dispensing System has pumped it's liquid supplies inside the washing machine.
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, as otherwise the machine will not finish the running wash cycle anymore.
DIAGNOSE:
1. Check if the Central Soap Dispensing System
operates correctly.
2. Check if the wiring of the input signal "On Hold"
is not damaged.
3. Check the electronic board.
(Inputs can be checked one by one in the
Service menu)
FAILURE 81: No Reheat
MB machine only. Failure 81 occurs when the heating is not restarted (at the wash sequence) when the
water temperature of the bath is below it's normal programmed value. When the temperature drops below the
predefined temperature 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 mean
that the linen can not be unloaded at the hygienic side of the MB-machine and 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
