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

This pressure switch assembly monitors the washer's tub water level and signals the control to fill, drain, and advance cycles properly. Replacing a faulty switch restores accurate water level sensing for reliable washing performance.

• Senses air pressure from the tub to determine water level
• Helps prevent overfilling and underfilling
• Common failure symptoms: overfills or won't fill, won't advance to spin/drain, drains continuously, or shows a PE (water level sensor) error
• Can cause intermittent cycle stops when readings are inaccurate

• Disconnect power and turn off water supply before servicing
• Access is typically from the top/console area; note hose and connector positions
• Inspect/clear the pressure hose; ensure it's not cracked, kinked, or blocked
• Seat the hose fully on the barb and reconnect the wire harness securely; test a fill cycle for proper operation
