Having problems with your Karcher 2500 PSI Pressure Washer ?

Honda pressure washer cuts out when lance trigger released.

\015 Hi I have a Honda 1600 psi pressure washer which starts just fine with the lance trigger pulled and will stay working as long as I keep the trigger pulled . On release the washer starts to sound like its labouring and then cuts out. It will restart immediately and keep going again until the trigger is let go again. Anybody any ideas thanks, BrianI have a similar problem but it is not the engine. It was checked out recently. When I pull the trigger on the wand it takes numerous tries until it starts and then everthing is fine until I release the trigger. Once I release the trigger I have to start over trying to get it to start again and so forth.\015

Answers :

When you release the trigger the pressure inside the pump rises above\015\012working pressure. Once it reaches a set control pressure (around 20%\015\012higher than working pressure) a sprung loaded piston actuates a switch\015\012thus stopping the machine.\015\012The machine will stay switched OFF whilst the pressure is trapped\015\012between the pump and the trigger gun valve.\015\012Squeezing the trigger releases the trapped pressure and the control\015\012piston returns to its resting position thus starting the machine. If a\015\012leak forms somewhere in the sytem the trapped pressure will leak away.\015\012The time taken for the pressure to leak away depends on the size of the\015\012leak.\015\012If the pressure is still full during normal use, your fault will lie in\015\012the outlet manifold - replace.\015\012Sometimes the leak can be from the inlet non-return valve or NRV which\015\012is located in the inlet elbow as the water enters the pump. Check for\015\012obvious leaks from the gun or hose connections.

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!

I have a 5HP Honda engine installed on a Excell pressure washer. While the engine readily starts, it will not continue to run unless I keep the choke setting nearly completely closed.

The engine will always cease running when I push the choke rod all the w

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. When this was working correctly, the pump would shut off when the trigger was released. Any suggestions?

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.


Sounds like the unloader is not working correctly. Try replacing it and see what happens. ... Briggs & Stratton Prosumer 20324 Gas Pressure Washer

I just purchased a Simpson Megashot V3000 Pressure Washer and noticed the engine would stop running every time I released the wand trigger.

I am thinking about returning it to Costco for a refund.
