Security fault
The door is open
Thermistor fault
1. Thermistor circuit open
2. Thermistor malfunction
3. The measurement value
for the thermistor is <300
Ω (>120°C)
Temperature fault
The temperature has
increased < 5°C in ten
minutes
The wash cycle should
continue to the next step
of the programme.
Wash motor fault
No signal from the tacho
or MCU.
Pressure fault
Indicated if the level drops
to zero within 30 seconds
of the first rinse.

Comment
The thermistor for measuring temperature is
located between the motor cradle and the drum.
The thermistor measures and controls the water
temperature, which can vary from 0 to 92°C. The
heater is disconnected if the thermistor is short-
circuited or disconnected from the programme
control card.
The drainage pump is combined with an
integrated fine filter trap, which can be cleaned by
the user. If the drainage pump has run for 3
minutes during draining, the programme stops
resets and a fault code is indicated on the display.
The pump has a capacity of 20 litres/minute.
Electromechanical level switch with two levels
(see wiring diagram). Used to indicate levels for
door opening, heat and overflow.
The filter eliminates interference to and from
the machine.
Two-way inlet valve, 8 litres/minute
The door lock is electromechanical and
equipped with a magnet.
