Hydraulic Circuit (Versions With Canister In Upper Section); Drum Rotation - Electrolux EDR1000NEW Service Manual

6.5 Hydraulic circuit (versions with canister in upper section)

1 – Pump immersed in the sump
2 – Water fill hose to canister (Red)
3 – Overflow drain hose (Transparent)
4 – Canister
The condensation water is ducted from the sump (1) to the tank (4) by the pump immersed in the sump via
the hose (2). When the canister is full the overflow is collected in the canister support and ducted to the
sump through the hose (3).

6.6 Drum rotation

1 – Motor
2 – Belt tensioner spring
3 – Belt tensioner
4 – Belt
The drum is rotated by a belt (4), which is driven by the pulley of the drum motor (1) fitted to the base; on the
bearing shield there is a belt tensioner (3), which has the function of increasing the winding angle of the belt
to the drum and works in conjunction with the belt tensioner spring (2).
Bidirectional operation of the drum rotation is determined by the electronic board which inverts the motor
power direction for brief periods. Reversal of the direction of rotation allows the clothes to unroll. During
these short periods, the heater unit is switched off.
The heat exchanger features a safety device which ensures that, if the panel is opened to check the heat
exchanger, a microswitch disconnects the dryer from the power supply.
