Simoniz pressure washer cycles whe not spraying?

Does this behavior change if the engine is warm and on minimum choke? Do you get any water spray before the engine quits? Carburetor could be dirty or float stuck. Try putting dose of carburetor cleaner through engine and cycle choke lever and engine speed lever back and forth while engine is running after it has warmed up without running water spray. See owners manual.

It could trip for a number of reasons. If you turn it on and nothing happens for a few seconds or instantly trips the motor is overloaded or burned up or a motor capacitor is bad. If the machine turns on and sprays if you hold the trigger open while you turn it on and then trips when you let go of the trigger you probably have a problem with the cut off switch . The circuit breaker might be too small for the load of your machine. The extension cord might be too light duty and causing the breaker to trip.

I have a similar problem and diagnosed it to be a problem with the gun. I spoke to a technician that services this pressure washer and he walked me through all the diagnostic steps. The pump is working because there is pressure being built up and the gun sort of works because you can get water out before the washer is started. The technician said that the mechanism inside the gun is either clogged or broken. I am going to Home Depot or Lowes to purchase a new gun and will try it tonight. Guns are only about $30-40. He said generic is fine as long as the thread matches and PSI is in range. Good luck!

Do you plan on doing the repair yourself. I need more info, when you supply water to the pressure washer, pull the trigger to purge air from pump, and start the machine. Do you see water coming out from the bottom of the pump? Do you hear the pump working or is it quiet. If you hear a cycling pattern or hear the pump trying to push the water out but it isn't, then you may have a blockage inside the trigger or the spray tip. If the pump isnt building pressure then you may have a pump problem. A stuck check valve, cracked plunger, bad seal, or could be air bound.

Hi my simoniz electrc power washer will not go off when I release the trigger , leaks trough the water inlet hose , I replaced the O rings but keeps leaking ..THANKS

With the water on, to the washer and the unit running. Does the water come out at the same rate before the trigger as at does after the trigger (run test with spray nozzle removed). Its not impossible for unloader valve to be bad but it usually is a dependable component. Make sure the unit has the air purged from it properly before start-up, make sure there are no obstructions before the trigger, then the nozzle. The unloader valve just puts the pump into by-pass until the trigger is depressed.

The machine has a pressure leak. Check for a cracked controll head or either a leaking outlet elbow. The machine will short cycle if the holding pressure can not be maintained

What a jacka$$ response.
Do you think its the seals? wow that describes f**Kall!!!
