Anti-Foam Control System - Electrolux TC2 Service Manual

11.11 Anti-foam control system

The anti-foam control procedure (if featured) is performed via the electronic pressure switch.
Spin phase without foam
Spin
450 rpm pulses
•
Spin with little foam: if the contact of the electronic pressure switch closes on FULL, the spin phase is
interrupted; the drain pump continues to operate and, when the contact returns to EMPTY, the spin phase is
resumed.
•
Spin with excessive foam in the tub (critical situation): The control system detects whether the
electronic pressure switch commutates 5 times to FULL. In this case, the spin phase is skipped, and a one-
minute drain cycle is performed with the motor switched off; in the case of a washing phase, a
supplementary rinse is added.
