Customer Questions and Answers for Water Level Pressure Switch by Whirlpool

This water level pressure switch senses air pressure from the tub and signals the control to stop filling at the correct level. Replacing a weak or failed switch restores proper filling, helps prevent over/underfilling, and allows cycles to advance.

• Monitors tub water level via the pressure hose and sends the level signal to the control
• Stops water flow at the target level so wash, rinse, and spin can begin
• Common symptoms of a failing switch: continuous filling, overfilling or underfilling, cycle won't advance past fill/sensing, or stops with water still in the tub
• A cracked, kinked, or blocked pressure hose can mimic switch failure—inspect during diagnosis

• Disconnect power and turn off water supply before servicing
• Access the switch from the console/top or rear panel per your model; note wire orientation
• Transfer and firmly seat the pressure hose; inspect it for kinks, cracks, or blockages and replace if damaged
• After installation, run a fill test; some models may require a diagnostic calibration—see the tech sheet or user manual
