I've had a couple little electric pressure washers. What I've found works is
to hook up the garden hose, and then squeeze the grip handle on the nozzle.
Leave the electric off. Eventually, the water will dribble out the nozzle
just from garden hose pressure. (ten or twenty seconds).

You may also have a clogged inlet screen, or something blocking the low
pressure water line.

As to the micro switch. The ones I've had, when you close the nozzle (let go
of the handle) the pump runs for a second or two, and then the micro switch
turns off the pump. When you sqeeze the handle, the pump turns back on.

My friend gave me his Simonize pressure washer which he told me worked when
he last used it ...3 years ago.

When I went to use it - I hooked up a water hose & a GFCI protected plug -
but the pump would not start.

I found a micro switch located after the main on/off switch was being
tripped by the pump mechanism & after I hit it - the pump started & ran -
but no water came out of the wand. I was careful to not run the unit for
more than a few seconds.

I suspect I have to 'prime' the unit - or - it may be the unit got ruined
when the previous owner put it away without draining it (it gets COLD here
during the winter).

Suggestions appreciated.
