Comments
All resistance values have tolerances
of ±8 %.
All resistance values have tolerances

The thermistor for temperature reading
is located between the motor cradle
and the container. The thermistor mea-
sures and controls the water tempera-
ture that can vary from 0 to 90°C. The
element is disconnected if the thermis-
tor is short-circuited or disconnected
from the programme control card.
The drain pump is combined with an
integrated fine filter trap, which can be
cleaned by the user. If the drain pump
has run for 180 seconds during drain-
ing, the programme stops, resets and a
trouble code is indicated in the display
(on machines without a display, the
LEDs flash).
See above.
Electro mechanical level switch with
two levels, see wiring diagram. Indica-
tes levels for door opening, heat and
overfilling.
ASKO level sensor type 1166. Controls
intake and level
The filter eliminates interference to and
from the machine.
3 way inlet valve 10 litres / minute
The door lock is electro mechanical
and equipped with a magnet.
