Wash speed

Relay K2 connects the wash speed windings on the wash motor. The

following conditions must be met for relay coil K2 (7) to be energised:

• The door must be closed and the programmer knob must be in

position I (see ”Power supply and start” sequence)

• Row M, stop (1) must not be programmed

• The drum speed must be less than 550 rpm (120 litre) or 310rpm (220

litre). If it exceeds this, speed control B31 (2) breaks to avoid

damaging the motor.

• The drain must be closed. (K31:51-52 (3) is closed when the drain is

closed). If the drain is open, the machine will run at distribution speed.

In this case, K31:51-52 (3) breaks, cutting out the wash windings on

motor M1.

If the above conditions are met, reverser motor M22 (8) starts. Reverser

contacts 1 (5) for normal action and 2 (6) for gentle action now open and

close according to a preset schedule (see diagram below). Switch S33

(4) on the front panel governs which of the two reverser contacts controls

relay K2.
