A line purge will help to expel air bubbles or foreign object debris from the machine. to do this:

  1. Turn on the power for pressure washer at the mains, leave main power switch in OFF position
  2. Detach the hose from the mains outside tap and ensure that there is a constant flow of water coming from it
  3. Reattach the hose to the tap and ensure there is a constant stream coming through the hose from the tap.
  4. Reattach the hose to the machine so that the machine is connected to the outside tap and then turn on the tap to full
  5. Pull the trigger on the gun until the water comes through in a constant unpressurized stream this can take up to 15-20seconds to purge the system

Once you have a constant uninterrupted stream of water flowing, switch the machine to the ON position, this should now function as normal.
