Water level sensor system function

The sensor system consists of a hose, giver housing and analogue
sensor.
5.16.1 Analogue sensor
The analogue sensor is based on the piezo-electric principle and
emits a voltage between 0.5 V = and 3.5 V =. There is no point in
measuring the emitted direct voltage as the analogue value in the
customer-service test programme is indicated on the display. The
analogue sensor is responsible for the different water levels in the
various wash programmes.
