How to Fix / Troubleshooting
Safety: Unplug the Husqvarna carpet cleaner and empty the solution tank.
- Flush system: Run warm clean water through the solution system to clear debris, then drain completely.
- Inspect nozzles: Remove and clean the spray nozzles to ensure they are not holding debris that wicks solution.
- Check valves: Access the pump outlet and any inline solenoid valves. Clean or replace the Husqvarna check valve assembly if it is not sealing.
- Store dry: After use, relieve pressure by running the pump briefly with the tank removed (if allowed by manual) to reduce post-drip.
