A faulty water level or pressure switch is one such unit.

It can have problems due to blockage in its pressure hose, or it can have an electrical malfunction.

The switch then signals the motor to begin agitating.

When the pressure reaches the critical point, the switch shuts off water flow to the tub.

Inspecting the Tube

Inspect the water level tube and, if necessary, clear any blockage.

Always unplug the machine from the wall outlet before doing any inspection orworking on your washing machine.
