DIAGNOSE:
FAILURE 39: EMPTY SOAP SUPPLY BOX
Failure 39 occurs when the electronic timer detects that the Soap Reservoir is empty.
To avoid that No Liquid Soap is added at the wash process, the operator gets a warning when a Liquid Soap
Supply Reservoir is almost empty.
DIAGNOSE:
1. Check if the Liquid Soap Supply is empty. Add Soap to the Liquid Soap Supply System.
FAILURE 41: SERVICE DUE WARNING
Failure 41 occurs when the cycle counter of the Electronic timer has reached the Programmed Value for
Service due. The fault message will be erased by opening the door. If the cycle counter has not been reset
the message will appear again at the end of the next wash cycle.
DIAGNOSE:
1. Check the cycle counter in the SERVICE INFO. You can reset the cycle counter in the Service
Menu.
FAILURE 42: NO NETWORK CONNECTION
Failure 42 occurs when there is No Network Connection available.
For more information about the networking see manual "TRACE-TECH".
FAILURE 43: WRONG VOLTAGE RANGE SELECTION
Failure 43 occurs when the wrong Voltage Range has been selected in the Configuration menu.
Depending on the machine type and the inverter type, certain Voltage ranges are not allowed.
DIAGNOSE:
1. Check the Machine Identification plate at the
back of the machine.
Select the same Voltage range in the Configuration
menu as on the Identification plate of your washing
machine.

switch) on a rigid-mount machine (i.e. machine without a safety switch).

back of the machine.
FAILURE 80: SOAP TIME OUT
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 its 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.
