My Cordless Pressure Washer is Leaking From the Trigger or Body of the Spray Gun

Quick Answer

If your cordless pressure washer spray gun is leaking, the issue will usually be caused by either a damaged internal trigger seal or small cracks/pinhole leaks in the body of the spray gun. In most cases, the spray gun will need to be replaced if the fault persists.

Before You Start

Before inspecting the spray gun:

• Switch the pressure washer off
• Remove the battery
• Turn off the water supply
• Squeeze the trigger to release any remaining pressure

Important: Never attempt to use or repair a leaking spray gun while it is under pressure.

Where Is the Leak Coming From?

Check carefully where the water is escaping:

• Water is leaking from the trigger
• Water is leaking from the body of the spray gun

Each issue has a different cause and solution.

1. Water leaking from the trigger

If water is leaking from the trigger area:

• The internal trigger seal is likely damaged or worn
• The seal is no longer able to hold water pressure correctly

This will typically result in water dripping or spraying from the trigger housing when the unit is in use.
