Why is my Kärcher Pressure Washer pump noisy?

A noisy pump in your Kärcher Pressure Washer could be due to the pump sucking air. Check that all hoses and fittings are airtight. Turn off the machine and purge the pump by squeezing the trigger gun until a steady flow of water emerges through the nozzle.
