DIAGNOSTIC CODE
The washing machine will not start a new process when the door is not locked after pressing the START button.
The Message DOOR is displayed.
When you open the door : the fault message is erased.
Exception :
If the „DOOR SWITCH" is opened again just before the cycle has started, (the „DOOR SOLENOID SWITCH"
is still closed) Diagnostic Code D14 will also be generated.
DIAGNOSE(ERR8):
1. Check if the input connector A is connected
2. Check the functioning of the
„DOOR SOLENOID SWITCH"
3. Check the door lock coil
4. Check the mechanical functionality of the
door lock
5. Check the continuity of the wiring
6. Check the output relay that powers the door
lock coil
7. Check the functioning of the „DOOR
SWITCH"
8. Check the door switch input at the wash
computer. (See Inputs at Toolbox Menu)
DIAGNOSTIC CODE
If the target water level is X units above the target level then failure Diagnostic Code D15 will be displayed.
The fault message will not be generated when the user is advancing from a sequence with a high water level
to a sequence with a low water level.
X= „Max. level Overfill", a value that can be programmed at the Initialization menu.
DIAGNOSE(ERR12):
1. Check if the water inlet valves are broken
2. Check if the water pressure is not to high
3. Check the output relay that powers the inlet
valve
In Case of Steam Heating :
If the steam has not enough heating power (too low temperature), the machine will be filled with too much
water at the heating part. This will result in an increased water, energy and soap supply consumption.
It's strongly recommended that the heating installation works with enough heating power.
A simple solution can also be to reduce the programmed target water level. As less steam will be required,
the normal water level should be reached. In the initialization menu it is also possible to adjust the alarm level
to avoid the error message. (= not recommended)
DIAGNOSTIC CODE
If the Gen 2 Debit Card Reader is not communicating for 5 minutes with the wash computer anymore failure
Diagnostic Code D16 will be displayed.
The fault message will be cleared automatically when the communication is restored.
