Customer Questions and Answers for Pressure Switch (Water Level) by Whirlpool

This pressure switch detects the washer's water level and signals the control to start or stop filling. Replacing a faulty switch restores proper fill behavior and helps prevent overfilling or failure to fill. What it does:

• Senses tub water level via the air hose and tells the control when to stop or start filling.
• Helps prevent overfilling, underfilling, or long/continuous fill cycles.
• Can cause fill-related faults or erratic washer behavior when the switch or its hose is clogged or failed.
• Works as the water-level input for the washer's control board.

• Disconnect power and shut off water supply before starting any repair.
• Inspect and, if brittle or clogged, replace the small air hose between the tub and the switch.
• Handle the switch and its electrical connector carefully; ensure connectors are fully seated.
• Test the washer through a short cycle after installation.
