9.10 Drain Pump -
FFLE3911QW and
FFLG4033QW
9.10.1 General Characteristics
The Drain Pump, which drains the water at the end of the
various washing cycle phases, is centrifugal and activated 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 a quarter of
a revolution approximately,
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.
WARNING
When replacing the Pump, refer to the code shown
on the list of spare parts related to the appliance.
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 be tested, once they
are fitted to the appliance, after some water has been
filled. The pumps are powered by the Main Control
Board through a Triac.
