Imbalance switch
Description
The imbalance switch is a safety feature which protects the machine from
damage during extraction caused by uneven distribution of the wash load.
The imbalance switch consists of a microswitch and a switch arm, mounted
on the left-hand front pillar of the frame. If the inner frame moves outside a
certain range, it will actuate the microswitch via the switch arm. As a result,
extraction will be halted and the PCU will switch to wash speed. After that
the PCU switches to distribution speed, before another attempt at
extraction.
If the imbalance switch is being triggered repeatedly, possible causes are:
•
Unsuitable wash loads.
•
The dampers are in poor condition, see Chapter 43. Frame.
•
High water level not programmed for extraction.
