Switch
The water level (pressure switch) system consists of a mechanical
pressure switch and an analog pressure switch.
Mechanical Pressure Switch
The mechanical pressure switch (orange) has (3) switching
positions:
•Water level < level 1
•Water heating level
•Overflow level
Analog Pressure Switch
The analog pressure switch (black) determines the different water
levels in the various wash programs. It is piezo-electric (pressure on
it generates a voltage) and generates between 0.5 - 3.5 VDC.

HINT:Its not helpful to measure the analog pressure

switch voltage because its shown on the digital
display while the washer is in the test program.
