Customer Questions and Answers for Tub Displacement Switch (Pressure Sensor) by Whirlpool

This tub displacement switch monitors water level/pressure to help the washer detect tub fill and balance, reducing overfill and load sensing errors. It replaces a worn or faulty unit to restore reliable fill and balance sensing. What it does:

• Senses tub water displacement/pressure changes so the washer can detect correct fill and load balance
• Helps prevent overfilling and supports proper spin cycles by reporting tub condition to the control
• Commonly replaced when washer overfills, won't start spin, or shows erratic fill behavior

• Disconnect power before accessing internal components to avoid shock
• Mounts to the washer chassis with electrical connector and vacuum/pressure hose; reuse existing hose if undamaged
• Verify hose and fittings are intact and free of blockages before installation
