Washing Machine Water Level Sensor Circuit

When the coil raises or lowers it changes the electronically resonant characteristics of the oscillator circuit.

Washing machine water level sensor circuit.

This is a video about fully automatic washing machine s pressure sensor that how to check and how does work it. How to replace the water level sensor in your samsung washing machine. Water level switch function. The water level is measured by the main board by frequency readings.

The tube is filled with air. It does this through a plastic tube which runs from the switch in the control console down to the side of the outer tub near the bottom. Hantek 3in1 digital oscilloscope waveform gen. The water level switch aka pressure switch senses the water level in the wash tub.

I ve never had a failed water level sensor. As water enters the tub it also enters the tube. The water level switch sends power from the timer control to the water inlet valve and the temperature switch each time the tub needs to be filled during a wash cycle. Thanks for watching our repair video.

The water level in most washing machines is well below 2 feet 0 87 psi so a pressure sensor that can measure 1 psi would work in this application. The water level frequency sensor operation is based on the displacement of the coil attached to the diaphragm.
