Dear Sir,
The power washer stops when the gun is closed. This happens because pressure is exerted on a control valve (Spill Valve)...which in turn touches a micro switch and cuts electricity. Now most probably your machine is cutting out because the spill valve is getting faulty or stuck down and closing the micro switch. This happens when one stores away the machine with pressure still in it. NEVER store a power washer with pressure in it. The spill valve also gets gammed and faulty because left with soap and machine not rinsed. I rarely service spill valves...I change with a new one.
To locate the spill valve open cover (using a TORX T15screw driver)...and where you see 2 wires coming out...there is the spill valve. If you can manage to do can try if you want to lubricate it by spraying SILICON spray. If you get it use silicon grease.
Sometimes these machines have the spill valve incoporated with the that case the whole head must be renewed. I wish to tell you to try using the machine without the lance. If it works correctly, then you have a faulty nozzel in the top of the lance. IMPORTANT...never run a power washer with water being fed!!!!
