Possible Causes

Worn tool trigger valve, Debris in tool nozzle, High residual line pressure, Damaged hose internal valve

How to Fix / Troubleshooting

Safety: Unplug the unit and relieve pressure by squeezing the trigger over a sink.

  • 1. Clean tool head: Remove the upholstery tool or stair tool and rinse under warm water. Clear any debris from the spray tip.
  • 2. Inspect trigger valve: Check the tool's trigger valve for smooth operation. If it sticks or does not fully return, replace the tool assembly.
  • 3. Check hose valve (if equipped): Some hoses have an internal shutoff valve. If dripping persists with a new tool, replace the accessory hose assembly.
  • 4. Storage tip: Store the machine with tanks removed or empty to reduce line pressure when not in use.
