Why is my pressure washer shutting off?
Also to know is, how do you turn off a pressure washer?
Shut down the pressure washer: Shut off engine and let cool. Turn off water supply. Relieve the pressure in the system: Press and hold spray-gun trigger until all water remaining in the line is expelled. Disconnect high-pressure and garden hoses from pump, and detach high-pressure hose from spray gun.
In this way, why does my power washer keep surging?
Water flow may be restricted to the pressure washer. Check that all hoses are free of kinks, leaks, or blockage. If the nozzle has even a little bit of dirt in the tip, it may cause enough obstruction for the pressure washer to pulsate.
For this reason you should not let your pressure washer idle, not spraying water for more than a few minutes. Without cooling the pump head the temperature will begin to climb to 200+ degrees. When it gets that hot, water seals and o-rings soften and wear quickly. Valves can be distorted and warp.
