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.
Its not helpful to measure the analog pressure
HINT:
switch voltage because its shown on the digital
