Drain

Relay K31 (5) controls the drain valve. The following conditions must be

met for relay K31 to be energised:

• The door must be closed and locked, and programmer knob must be in

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

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

• The out-of-balance switch must not have tripped (breaks

K53:51-52 (2) power supply).

• Row K, drain (3) must be programmed.

• Reverser, row 3b (4) must be closed.

The machine will run at distribution speed if the drain is activated. Row

3b is used to ensure that the motor windings are switched in at the right

speed. For more details, see ”Distribution speed”.

When K31 is energized, K31:71-72 (7) cuts the power supply to the drain

valve Y1 (8) and the drain valve opens.

The drain valve can also be controlled manually via switch S34 .
