Alliance Washer Switch

The Pressure Sensor is an OEM part for Speedqueen commercial washers. It plays an important safety role by actively monitoring water levels and pressure changes within the washing machine. Located internally, the sensor communicates water level status to the control module.

Causes of a bad pressure sensor can include failure or degradation of electronic components over time. Damage from impact or liquid ingress may also cause sensors to malfunction.

Symptoms of a bad Pressure Sensor include:

• Erratic or inconsistent water levels during fills and drains
• Inability to detect rises or falls in water pressure
• Fault codes or error messages on the control panel
• Safety issues from unregulated water valves

This replacement switch assembly restores the appliance's electrical switching function so the control or safety circuit can open and close when activated. Use it to replace a worn or failed switch and regain expected control response. What it does:

• Acts as the electrical contact that opens or closes a circuit when toggled or pressed
• Commonly used where a user action or door/lid position must be sensed by the control
• Can address symptoms such as no start, unresponsive controls, or intermittent operation tied to the switch circuit
• Transfers the mechanical action to the appliance's control or safety system

What's included: One switch assembly Install notes:

• Disconnect power to the appliance before beginning any repair to avoid shock or injury
• Verify correct wiring and connector orientation before reassembly; take photos if needed
• Test switch continuity (with power off) after installation to confirm correct operation
