Programmer advance
The timer motor advances in the following way:
From timer rows
Rows 9a (1) and 11a (3) are closed during all drain and spin cycles. They
are also closed during the first of the wash and rinse cycles when water is
filling.
From level sensor
When water fills to the correct level, the level sensor's contact changes
over and point F in the diagram receives voltage (see section on "Water
filling"). During those cycles when timer rows 9a (1) and 11a (3) are open,
the level sensor controls the advance of the timer motor. As a result, if
water does not fill to the correct level, the timer will stop.
At program rapid advance
Contact K51 (2) closes when the program is rapid advanced so that the
motor always receives voltage.
At heating
At stages 8, 17, 27, the programmer advances switches off internally in the
timer even if the motor is still energised. Stages 8 and 17 are used for
heating water. Machines without heating rapid advance past this stage (see
section "Rapid advance, program selection").
