What causes unloader cycles when trigger gun is opened or closed on Hotsy 1836SS?

The unloader cycling when the trigger gun is opened or closed on your Hotsy pressure washer could be caused by air in the system; try opening and closing the trigger gun several times. It could also indicate a defective unloader, which would need replacement. Another possible cause is a water leak between the unloader valve and trigger gun; check the fittings, hose, and trigger gun for leaks, and repair or replace as necessary.
