Function & Importance of the Washer Pressure Switch

The washer pressure switch is responsible for monitoring and controlling the water level inside the washing machine. It works by sensing air pressure changes through a connected tube as the tub fills with water.

Key functions include:

• Signalling the washer to stop filling at the correct water level

• Ensuring proper wash and rinse cycle performance

• Preventing overflows and water damage

• Supporting efficient spin and drain operations

A properly functioning pressure switch is critical for maintaining safe, efficient, and consistent washer performance. Using a high-quality replacement like the LP1703B ensures accurate sensing and dependable operation.

Common Symptoms of a Faulty Pressure Switch

If your washer shows any of the following issues, the pressure switch may be defective:

• Washer overfills or underfills with water

• Machine won’t stop filling or keeps adding water

• Washer won’t start or complete cycles properly

• Inaccurate water levels during wash cycles

• Water-related error codes or cycle interruptions

These symptoms are commonly associated with pressure switch failure, as it directly controls water level detection.
