Why won’t my pressure washer keep running?
A clogged carburetor is most commonly caused by leaving fuel in the pressure washer for a long period of time. This sticky fuel can clog up the carburetor and cause the engine to run stall. If the carburetor is clogged, try cleaning it with carburetor cleaner.
Why does my pressure washer shut off when I let go of the trigger?
If a pressure washer stalls when the trigger is released, this usually indicates a fault in the unloader valve. It is a simple process to remove and replace the unloader.
Why does my greenworks pressure washer keeps shutting off?
A Greenworks pressure washer keeps shutting off due to a problem with the unloader valve. A faulty unloader valve doesn’t divert the water to the inlet, which increases pressure inside the pump, and the washer shuts off. To solve this problem, carefully inspect the unloader valve’s springs and other components.
How do you know if your unloader valve is bad?
Pump motor stalling – if a pump is powered by a gasoline or diesel engine, stalling whenever the operator ceases to use it is a good sign of unloader valve failure. The buildup of pressure locks the pump’s internal components, which in turn prevents the rotation of the powered engine shaft.
Can you start a pressure washer without water?
Although you can start a pressure washer without water, it is not advisable to do it. The water helps to lubricate the pump and help to keep it cool. Without the lubrication and cooling properties of the water, dry starting will cause the pump to wear down quickly.
Do you turn water on before starting pressure washer?

Why is my pressure washer pulsing?
Why is my pressure washer 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.
