How to fix a pressure drop in my Nilfisk-Advance Pressure Washer?
- DDesiree McdanielAug 14, 2025
If your Nilfisk-Advance Pressure Washer experiences a pressure drop, there are several potential causes. First, air might be trapped in the system; vent it by operating the spray gun at short intervals. If necessary, run the cleaner briefly without the high-pressure hose connected. Also, a blocked or worn high-pressure nozzle can cause pressure loss, so clean or replace it. Ensure the pressure control on the spray lance is correctly set to your desired working pressure. Check that the detergent container isn't empty, and replace it or close the detergent valve if needed. Finally, verify that the water inlet temperature is within the specifications outlined in the technical data.
