B4 Checking operation of and/or replacing the float switch
The two float switches in the detergent and dirty water tanks indicate (acoustically with a
buzzer and visually by an LED on the control panel and information on the display) when the
dirty water tank must be emptied or the detergent tank requires filling.
The operating principle of the float switch is very simple. The floating moving part A contains a
small magnet, while the fixed body B contains two metal strips, one of which is flexible. When
the magnet in the moving part A approaches the fixed body B, the flexible metal strip is
attracted towards the other metal strip and the electrical circuit is closed. This is audible.
Dirty water tank float switch
The magnet is distant from the flexible metal strip
and the circuit is therefore open.
The digital multimeter will not detect electrical continuity.
The magnet is near th
flexible metal strip and the
circuit is therefore closed. The
digital multimeter will detect
electrical continuity.
