11.11 Anti-foam control system
The anti-foam control procedure is performed using the electronic pressure switch.
 Spin with little foam: if the pressure switch senses a “full” level, the spin phase is interrupted, the drain pump
continues to operate and, when the pressure switch senses “empty”, the spin phase is resumed.
 Spin with excess 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.
