When replacing the pump, please refer to the code shown in the list of spare parts
relating to the appliance.
11.3.1 General characteristics
1. Wheel
2. Rotor
3. Stator
The pump, which drains the water at the end of the various washing cycle phases, is centrifugal and is actuate by a
synchronous motor.
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.
The flow rate of these pumps is approximately 18÷20 l / min, and the maximum head is 90 cm. above ground level.
Fitted with overload cut-out.
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 drain pump is powered by the main circuit board through a triac, as follows:
For a pre-determined period (and an alarm might be displayed - see table of alarms).
Until the electronic pressure switch closes on empty, after which the pump is actuated for a brief period or passes
to the subsequent phase.
