11.11 Anti-foam control system
The anti-foam control procedure is performed via the electronic pressure switch.
Spin phase without foam
Spin phase with little foam
•
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 switches 5 times to full (five spin interruptions). If this occurs, the spin phase is
skipped, and a one-minute drain cycle is performed with the motor stationary and, in the case of a washing
phase, a supplementary rinse is added.
