8.8. EXPLANATION ERROR MESSAGES

DIAGNOSTIC CODE
If the level sensor is broken then Diagnostic Code D1 will be displayed. The fault is only generated when the
machine is in standby mode and no program is active.
The fault can only be erased by switching off and on the power.
DIAGNOSE(ERR24):
1. Check the level sensor visually
2. If the fault is persistent
DIAGNOSTIC CODE
When the temperature sensor is broken then Diagnostic Code D2 will be displayed. The fault is only
generated when the machine is in standby mode and no program is active.
The fault can only be erased by switching off and on the power. If the fault is still active after switching on the
power : fault 25 will be activated again.
DIAGNOSE(ERR25):
1. Check if the temperature sensor is
connected on the PCB Board.
2. Check the temperature sensor
3. Measure the resistance of the sensor
4. Check if the earth wire is at the middle
position of the connector
5. Check the PCB board visually
6. If the fault is persistent
DIAGNOSTIC CODE
Diagnostic code D3 occurs when the cycle counter of the Electronic timer has reached the Programmed
Value for Service due. A symbol will be displayed at the LCD display, to warn the operator that a service due
must be executed.
DIAGNOSE(ERR41):
1. Check the cycle counter at the Toolbox Menu
(Service Menu).
DIAGNOSTIC CODE
For safety reasons : while a process is running the door lock system is scanned all the time.
If the controller detects that the „DOOR SWITCH" is not closed then the machine will immediately stop all its
functions. The door will stay locked.
DIAGNOSE (ERR6):
1. Check the well functioning of
the „DOOR SWITCH". The „DOOR
SWITCH" is a NO normal open contact.
2. Check the continuity of the wiring
3. Check the door switch input at the wash
computer. (See Inputs at Toolbox Menu)

D1 : DEFECTIVE LEVEL SENSOR
If you see some damage: replace the PCB board
Replace the PCB board (be sure that there is no drain
problem)
D2 : DEFECTIVE TEMPERATURE SENSOR
The Female connector must be connected with the
Male connector T of the PCB board.
If the temperature sensor is broken: replace the
temperature sensor
If the resistance is not OK: replace the temperature
sensor
If the earth wire is not at the middle position: put the
earth wire in the middle position of connector T
If you see some damage : replace the PCB board
Replace the PCB board
Be sure that the problem is related to the PCB board
and not to a defective temperature sensor
D3 : SERVICE DUE WARNING
D4 : DOOR SWITCH FAILURE
If the „DOOR SWITCH" is broken or malfunctions
replace the door switch
If the wiring is not continuous: repair the wiring
If the wash computer input is not functional replace the
wash computer board.
PROGRAMMING MANUAL
You can reset the cycle counter in the Service
Menu.
