How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
A clogged carburetor is most commonly caused by leaving fuel in the pressure washer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to run stall.
If the spark arrestor is dirty or damaged, it can cause the engine to stall. To clean the spark arrestor, you will need to remove it from the pressure washer and use a wire brush to remove any build-up. Once the spark arrestor is clean, you can reattach it and try starting the power washer again.
The number one cause of low or no pressure when using a pressure washer is a blocked or worn nozzle. Blocked nozzles will prevent water from escaping, while a worn nozzle will allow too much water to pass through, causing the pressure to drop.
How Do I Tell If My Unloader Valve is Bad? In most occurrences, the first symptom of an unloader valve going bad is no pressure from the wand when the trigger is pressed. This happens when the unloader valve gets stuck open and does not allow water to enter the hose and trigger.
A dirty inlet or discharge valve is the most common cause of a pulsating pressure washer. Dirt or hard water can get caught up in these little divots. It is important that you clean out these pieces every so often to prevent these kinds of problems.
Connect and Turn On the Pressure Washer
Connect the high-pressure hose to the pressure washer, then turn on the pressure washer and set it to the lowest power setting. Make sure that the nozzle is pointed away from you in the direction of the target surface. Grip the wand and pull the trigger to start spraying.
If you find that your washer is routinely stopping during the rinse cycle, then it may be caused by a faulty water inlet valve. As it stops during the rinse cycle, the washer will stop in the middle of the wash. It will not advance likely because it reads that the water level is too low.
Pressure washers operate under pressure, and that pressure needs to be released by pulling the trigger. If you let the machine run for two minutes or longer without spraying water, then you could damage the pump.

Motor starts, stops, starts, stops etc never running completely. not putting out much water pressure. not building pressure??
Is you nozzle plugged? That is what this sounds like.
Starts great and sprays great, but will not continue to run when [ stop spraying. It locks up until I release the pressure from the gun.is there a pressure by-pass adjustment I can make?
Tune up motor, replace air filter/spark plug and oil.
This pressure washer will continue to build pressure when you let off the trigger. I have replaced the hose 3 times because the pump continues to pump until it blows the hose. The pump will not stop pumping!
You have a defective pressure release valve or someone has misadjusted.
Need help in getting Honda engine on NorthStar pressure washer to run.
Could be low water pressure I have found.Also, I purchased a can of “stuff” at Lowes today which allows you to circulate a liquid substance which lubricates the pressure pump….the pump could be frozen up…I have a rotating nozzle which I bought…and it had frozen up…this stuff works
1750 psi Electric Pressure Washer: My pressure washer is losing pressure and is pulsa…
If the pressure washer is pulsating then that is a sign of check valve failure. You may be able to clean of replace the check valves. Replacing the head is the wrong way to go. This is completely unnecessary. If you can tell me the model number of your pressure washer then I can assist you better in pointing you in the right direction.
I have used the McCulloch (FH180A) three times over the course of two years. On my fourth use the pressure washer just surged on and off and I would get a tiny spray from the gun each time it surged. In other words it would do nothing. Please help… very frustrated. Thanks
Sounds like the problem could be low input water flow or pressure. There could be crud on the intake where you hook up the garden hose, there could be some other sort of blockage. Try hooking it up to the hose and pull the trigger (with the power switched off) and wait to see if water comes out the tip. Also look at the tip(s) themselves. sometimes a piece of crud gets into the hose and then clogs the tip.

Sounds like the unloader (regulator). Try removing the nozzle, the pull the trigger with the engine running. If motor is still running then it could be the Unloader malfunctioning. If you require a new one try a bypass system for the unloader. The bypass will help save the life of the unloader.
