Water Circuit; Drum Rotation Principle - Electrolux 6 Series Service Manual

3.3.3 Water circuit

1 Pump immersed in the trap.
2 Tank water drain pipe (red).
3 Water overflow drain pipe (transparent).
4 Tank support.
5 Level sensor.
The condensation water that forms inside the exchanger is collected in a trap.
There is a float (5) inside this trap that informs the circuit board that there is water. This powers a pump (1)
which conveys the water through the red pipe (2) from the trap to the tank inserted in the tank support (4).
The tank was designed to receive the condensation water of a complete cycle at full load, approximately
5.5 litres.
If, for whatever reason, the tank fills up beyond its capacity, the overflowing water is collected by the support
tank and via the transparent pipe (3), is re-conveyed inside the trap pushing the float (5) upwards and this
activates the micro-switch. The electronic makes 7 attempts to empty the trap within a set time, after which
the electronic control recognises the problem and disconnects the power supply to the appliance and lights
up a LED informing the user that the tank is full.

3.3.4 Drum rotation principle

1 Motor.
2 Inverter motor board support.
3 Belt tensioner spring.
4 Belt tensioner.
5 Belt.
The drum is turned by a belt (5) which is driven by a motor pulley (1) fixed to the base.
There is a belt tensioner (4) on the motor casing, which increases the angle at which the belt winds onto the
drum and works in a pair with the belt tensioner spring (3).
Two-way rotation of the drum is determined by the circuit board, which reverses the direction of power
supplied to the motor briefly. The drum rotating in the opposite direction allows the washing to untangle.
