Solenoid valve broken
alarm
Any time the machine detects movement of the turbine for ten seconds with
the fill solenoid off, a fault will be signalled.
It stops all water fill processes and activates the drain pump.
NTC circuit
alarm
The NTC circuit alarm is signalled after the electrical circuit is open or closed
for 9 seconds.
It stops all water fill cycles and activates the drain pump.
Time out water heating
alarm
The water temperature not reached timeout alarm is given when the water
temperature does not increase during 60 minutes of washing.
It stops all water fill processes and activates the drain pump.
Time out drain
alarm
If the machine does not detect open pressure switch contacts 4 minutes into
the drain cycle, the fault is signalled.
All water fill processes are deactivated, only the drain pump stays on.
Time out fill
alarm
If the machine does not detect turbine rotation and the pressure switch
contacts close 1 minute and 30 seconds into the drain cycle, the fault is
signalled.
It disactivates all water fill cycles and activates the drain pump.
Clogged filters
alarm
If the pressure switch contacts do not close after a water fill cycle the filter
cleaning programme will be run. After serving the pressure switch by
continuing to fill up to 6 litres, the machine will start to wash for 6 minutes.
After this the water will be drained. A further two litres are then filled to check
if the pressure switch contacts close. If this continues to remain open, the
alarm is signalled. It disactivates all water fill cycles and activates the drain
pump.
Software setup
alarm
The type of software is not recognized in Eeprom. The cycle status LEDs
signal the alarm.
Heating element circuit
alarm
The heating element circuit alarm is signalled when the timer sees the
washing heating element circuit open for 9 seconds.
These 9 seconds start from the moment the pressure switch contacts close. All
water fill processes are disactivated, only the drain pump stays on.
