The following conditions must be met for relay K21/valve Y51 (11) to be

energised:

• The door must be closed and locked, and the 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 not be programmed

• The drum must be filled with water to the correct level.

Level control B1 (6) has two closing contacts, 21-23 (low water level)

and 31-33 (high water level). Which of these is active depends on

whether row N (5) is programmed or not.

If the above conditions are met, the closing contact in thermostat B11 (10)

is energised.

The thermostat has three different temperature settings, using the three

dials B, D and F. Which setting the thermostat is to follow depends on

whether row B (7), D (8) or F (9) has been programmed on the program

card.

If any of the three rows are programmed, and the water temperature is

lower than the set temperature, the closing contact 11-13 in the thermostat

switches and relay K21/valve V51 (11) is energised.
