    Service Manual IW 1209.0W / IWT 1259.0W 5.6 Motor Speed Control 1. Control unit 2. Motor Motor speed control is regenerative via a TY4 triac. The rectifier (GR2) converts AC to DC to supply power to the motor. The switching of the motor windings (M) and the stator (ST) needed to change the motor’s rotational direction is performed using a relay (K1) located in the control unit.
  • Page 32 Service Manual IW 1209.0W / IWT 1259.0W 5.6.1 Foam Control A pressure switch monitors foam build-up during the spin programmes. This improves the efficiency of the rinsing operation even when the water level is low. If the pressure switch actuates when draining on spin, signifying the presence of foam in the tub, power is cut to the motor and the spin cycle is interrupted.
