Customer Questions and Answers for Hose, Pressure Switch (Tub-To-Switch) by Whirlpool

This pressure switch hose carries air from the washer tub to the pressure switch so the machine can sense and control water level. Replacing a damaged hose restores proper fill control and prevents level-sensing errors. What it does:

• Channels air/vacuum from the tub to the pressure switch so the control can detect water level.
• A cracked, pinched, or collapsed hose may cause overfilling, underfilling, failure to advance cycles, or continuous fill.
• Restores accurate water-level sensing when replacing a worn or damaged hose.

• Disconnect power to the appliance before servicing to avoid shock or injury.
• Remove and replace the hose carefully; avoid kinks, sharp bends, or pinched routing that can impair sensing.
• Use the factory-style connection points and clamps; ensure both ends are seated securely.
• After installation, run a test fill or diagnostic cycle to confirm correct water-level operation and no leaks.
