How to Fix a Pressure Switch for a Washer That Has Spinning Issues

The pressure switch is responsible for informing the control panel whether the machine has been filled or emptied. The pressure switch is vulnerable to electrical failure if the electrical contacts become damaged. If the switch also has a hose attached to it that may be clogged or worn down from use. If the switch is indeed defective, the tub may not drain properly. This would cause the washer to not move forward to the spin cycle, or it may spin while the tub is still full, resulting in soaking wet clothes. If you need a new pressure switch, this expert guide will make you feel confident in your ability to find the pressure switch in your washer and show you how to remove the defective one and replace it with a new one if need be.

What is a Pressure Switch?

The pressure switch helps to determine the water level in your washer. While the tub is filling or draining, air inside the hose will press against a diaphragm inside the switch. The more water that is in the tub, the more pressure is applied to the switch. When a certain level is reached, the switch will indicate that the tub is full and stop it filling with water. It also sends power to the motor or control board, in order to start the drive motor.

Where is the Pressure Switch Located?

The pressure switch is located behind the control panel of your washer.
