home and garden home appliancesHow do you fix a water level sensor on a washing machine?
Similarly, how does a water level sensor work in a washing machine?
The water level switch (aka pressure switch) senses the water level in the wash tub. 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 . The tube is filled with air. As water enters the tub it also enters the tube.
Water Level Setting | Typical Load Size |
---|---|
Small | Less than 1/3 full of clothes |
Medium | Between 1/3 and 1/2 full of clothes |
Large | Between 1/2 and 2/3 full of clothes |
Extra Large and Super | Over 2/3 full of clothes |
Herein, how do you check a water level switch on a washing machine?
To test the switch for continuity, use a multimeter (also called a volt-ohm meter) set at OHMS x 1.
- Find the wires leading to the terminals of the switch.
- The water level switch has three terminals.
- Touch the probes to terminals 1 and 3, and note the reading (∞ or approximately 0.0).
A common cause of a washing machine not taking any water in is either a kinked fill hose, or the tap becoming faulty. Some taps can become clogged up, others can jam inside. Other causes can be wiring faults, water valve faults, PCBs or pressure system faults.
