WARNING

When replacing the Pump, please refer to the

code shown in the list of spare parts relating to

the Appliance.

8.1 Pump

There are more than one pumps used for this model:

• Drain Pump

• Recirculation Pump

• Concentrated Wash Pump

8.1.1 General Characteristics

1. Wheel

2. Rotor

3. Stator

The Drain pump, which

drains the water at the end

of the various washing

cycle phases, is centrifugal

and is activated by a

synchronous motor. Also,

Recirculation Pump is used

for recirculating the wash

water.

The rotor consists of a

permanent magnet and

the direction of rotation

can be either clockwise or

anticlockwise.

It can turn by approximately

a quarter of a revolution

without turning the wheel.

Consequently, if a foreign

body is stuck in the wheel, the rotor can perform small

movements clockwise and anticlockwise until the

foreign body is released.

IMPORTANT

Synchronous pumps, when powered on empty

(disconnected from the water circuit), may

not start in some cases because their very

construction makes them need an antagonist

torque on the wheel to allow the rotor to move in

one of the two directions.

The pumps should therefore only be tested once fitted

to the Appliance after a little water has been filled.

The pumps are powered by the Main Control Board

through a TRIAC.
