Hydraulic Circuit; Drum Rotation: Principles - Electrolux ENV06 Service Manual

5.5 Hydraulic circuit

1. Water overflow drain tube (transparent)
2. Water fill hose to canister (red)
3. Pump
The condensation water coming from the sump is ducted to the canister by the pump (3) (immersed in the
sump) through the red tube (2).
When the canister is full, the overflow is ducted through the transparent tube (1) back to the sump.

5.6 Drum rotation: principles

1. Motor
2. Belt tensioner spring
3. Belt tensioner
4. Drive belt
The drum is rotated by a drive belt (4), which is actioned by the pulley of the motor (1), which is anchored to
the base of the appliance. The motor casing is fitted with a belt tensioner (3) which operates together with
the tensioner spring (2) to increase the winding angle between the belt and the drum.
The bi-directional moment of the drum is controlled by the electronic control system, which inverts the power
supply to the motor for brief periods. Reverse rotation of the drum allows the wash load to become
untangled. During these brief intervals of reverse rotation, the power supply to the heater is disconnected.
When the access panel is opened to check the heat exchanger, a microswitch is tripped and disconnects the
power supply to the appliance.
