Analogic Pressure Switch - AEG Electrolux EMW2000 Service Manual

ANALOGIC PRESSURE SWITCH

The analogic pressure switch controls the water level in the tub, it is directly connected to the electronic
modul.
If the pressure switch does not work correctly, the programm in progress is cancelled:
1. Pressure switch hose connection
2. Diaphragm
3. Coil (self)
4. Electronic circuit (oscillator)
5. Magnet
6. Spring
7. Adjusting screw
8. Connector
Kontakt 1 = Out
Kontakt 2 = GND
Kontakt 3 = 5V DC
When the tub is full, the pressure inside the hydraulic circuit acts on the diaphragm which moves the
magnet inside
the coil.
This moving modifies the inductance of self and consequently the frequence delivered by the scillatory
circuit. the µP, after frequence reading, recognizes the water level inside the tub. (see Page Service -
