Programmer advance
The programmer stops at three stages in the wash cycle: during water
filling, heating and if the out-of-balance switch trips.
The following general conditions must be met for the programmer to start:
•
The door must be closed and locked, and the programmer knob must be
at I (see ”Power supply and start” sequence).
•
Row M, stop (1) must not be programmed.
The events at the different stages in the wash cycle are as follows:
•
Water filling
The programmer motor (11) stops since both level control (6) switch
contacts are in the left-hand position. Once the correct level is reached
(depending on how row N (5) has been programmed), the level control
contacts switch, and the programmer motor is energised again.
•
Heating
During heating, thermostat B11 (7) switch contact is in position 11-13.
This cuts off the power to the programmer motor. Once heating has
finished, the contact switches to position 11-12, and the programmer
motor is energised again.
•
Out-of-balance
If the out-of-balance switch trips, relay K53 opens (see ”Out of balance”).
K53:51-52 (2) then cuts the power to the programmer motor. At the end
of the out-of-balance sequence, K53:51-52 closes again.
•
Drain and extraction
During the drain phase, row K (3) is in position 1-3. Relay K31 is
energised during drain. In this case, K31:13-14 (9) is closed and the
programmer motor is energised, even once the water level has dropped
so that the switch contact on level control B1 (6) cuts the power.
Since draining also must be programmed during extraction, the above
conditions also apply during extraction.
