Conductivity Sensor; Tank Filling Pump; Level Sensor - Electrolux 6 Series Service Manual

4.4 Conductivity sensor

These electronics use a conductivity sensor,
comprising an electronic circuit (located inside the main
circuit board) and a part outside the board comprising
two sensors positioned on the front air conduit.
When the drum is empty, there is an infinite impedance
between the two sensors, while its value is affected by
the washing load, by the type of fabric and by the
degree of humidity in the washing placed inside the
drum.
The main circuit board continually receives information
regarding the status of the washing in the drum via the
conductivity sensor as well as the settings made by the
operator at the start of the cycle via the control board
and elaborates these values in order to establish the
time needed at the end of the cycle.

4.5 Tank filling pump

The pump is activated by a synchronous motor and
is used to pump condensation water from the tray to
the tank.
The pump is powered by a triac on the main board.

4.6 Level sensor

The condensation water level sensor is located at
the back of the tumble dryer and next to the tank
loading pump.
It consists of a float with a magnet at the top and a
reed switch positioned on the float guide / support.
When the water forming on the heat exchanger
(capacitor) falls into the collection tray this causes
the float to rise up subsequently bringing the magnet
closer to the reed switch which sends a signal to the
main circuit board activating the tank loading pump.
