80 617 06
Heating Element
2000 W
28.4 Ω
80 761 02
Thermistor
6.1-3.8 k
Ω (at room temperature
20 – 30°C)
The thermistor for temperature reading
is located between the motor cradle and
the container. The thermistor measures
and controls the water temperature that
can vary from 0 to 90°C. The element is
disconnected if the thermistor is short-
circuited or disconnected from the
programme control card.
88 012 63.
Drain pump 50 Hz
144 Ω.
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).
88 012 64.
Drain pump 60 Hz
76 Ω
See above.
80 782 21
Level Switch
Electro mechanical level switch with
two levels, see wiring diagram. Indicates
levels for door opening, heat and overfil-
ling.
80 616 64
Pressure sensor
0.5 V out from the
sensor (at 0 bar pressure
and 230 V mains vol-
tage, measurement car-
ried out with the drain
pump running to ensure
0 level is reached)
ASKO level sensor type 1166. Controls
intake and level
80 762 02
EMC filter with inductor
50/60 Hz
The filter eliminates interference to and
from the machine.
80 762 01
Inlet valve
3,7 kΩ ± 0.5 kΩ
3 way inlet valve 10 litres / minute
80 616 79
Door lock
122 Ω
The door lock is electro mechanical and
equipped with a magnet.
