How to fix pressure drop in my Nilfisk-ALTO POSEIDON 3?

If your Nilfisk-ALTO Pressure Washer experiences a pressure drop, it might be due to several reasons. First, there could be air in the system; try venting it by operating the spray gun at short intervals, or run the cleaner briefly without the high-pressure hose. Alternatively, the high-pressure nozzle might be blocked or worn, requiring cleaning or replacement. Ensure the pressure control on the spray lance is correctly set to your desired working pressure. Check if the detergent container is empty and refill or close the detergent valve. Finally, verify that the water inlet temperature is within the specified limits.
