Common for not starting unless trigger engaged as you are turning the pump as well as engine creating pressure,as for stalling pump has unloader valve which is probably in need of grease(use good silicone grease)this allows water to ciculate when trigger released.

Turn water on then actuate wand trigger. Pressure washer leaks when wand trigger is actuated and has very low pressure/flow output. After releasing trigger the pressure cycles on - off at approx 1 second interval. I suspect that the plasstic oulet tube is leaking causing low pressure leak out of bottom when trigger is actuated and causes pressure switch to cycle when the trigger is released. Any Help? This pressure washer is approx 18 months old!


You gave a very close solution yourself for the problem. But other leakages can cause such symtoms.Forexample a leaking head or a leaking chemical inlet. These can be caused because the spill valve (pressure control valve) is stuck. When this valve s ... Karcher PSI Electric Pressure Washer

I have a McCulloch FH160B power washer and it no longer builds up pressure. I haven't used this very much at all. I tore it apart and cleaned everything I could find. When i pull the trigger for the spray nozzle, I get line water pressure. When I release the trigger, the power washer sounds like it starts to build up pressure.

My Karcher K3.48M pressure washer remains in the low pressure mode even when I return the pressure nozzle to the high pressure position. How can this be corrected. The pump seems to build up the pressure because when I release the handle the pump motor stops. This is a fairly new pump which was purchased in the latter part of last year(2010). Could this have been caused by the detergent I have been using which is an automotive shampoo? Please help I love this washer and for the times that I u

I just purchased a Simpson Megashot V3000 Pressure Washer and noticed the engine would stop running every time I released the wand trigger. Also, water was constantly spraying out of a valve underneath the unit - I assume it's some type of pressure release valve but there is no mention of it in the owners manual. I am thinking about returning it to Costco for a refund.

I have a Briggs & Stratton gas power washer. This is the 1st time this year that I have used it. I put in fresh gas, hooked up the water supply. The engine started and then quickly stopped. I had to release the water pressure in the hose before I could pull start the engine. The only way to keep the engine running is to hold down the spray nozzle trigger. Once that is released the pressure in the hose builds up and the engine stops.
