Function

Electric heating

The three heating elements in the machine are
connected to separate phases and are switched
on and off using one or two heating contactors,
K.21 and K22 (two contactors are used for higher
heating power). The heating contactors are
controlled by the programme unit and thermostat
B1.

The programme unit receives information on the
water temperature in the machine from the
thermostat situated in the outer drum. The
programme unit controls the heating contactors
to achieve the set water temperature for the
current washing programme.

When there is no water in the drum, the
programme unit prevents switch-on of the
heating elements. If an error would nevertheless
cause the elements to switch on, a slow-blow
fuse triggers to switch them off again.Then the
heating element has to be changed.

Steam heating

The steam valve is controlled by the programme
unit A1. The control signal goes via the
communication card A21.
