It is possible that the oil pressure switch is not functioning properly or you have a lighter oil in the machine than is recommended.

You need to start the unit and let it run for few minutes to get worm, make sure the water is fully open and the unit is fully cleaned. Push on the trigger on and off for few times not letting the unit shutdown, then start increasing the fuel mixture ¼ turn and push on the trigger again and see…this could be that the unit need service or the governor springs getting week if you got one on your unit…let me know how that work for you and please do not forget to rate my service so we can improve on it with your help. God bless

Their is an oil level sensor that lasts around 3 months of use. unplugging it would solve your problem But replacing it is a night mare. and if your oil runs out It's all over. if not the oil sensor, and your spark is constant Check your fuel system for water and debrie. Those pumps can run dry all day long.

Frank, either the unloader valve is out of adjustment(try loosening it off) or it is faulty and needs rebuilt or replaced as most people do.
Check the attached vids,instruction and guides, Good luck

My honda excel 2600 psi pressure washer do not have any pressure when i squeez the trigger


Trash in, worn or damaged inlet and outlet valves are one possibility. Unloader valve stuck open or badly worn would also cause low pressure. Wrong spray nozzle size is another. Is the nozzle the right size for your pump?
Is water leaking from under the pump? That would show worn high pressure seals.

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

Power washer stalls after spraying


Your pressure relief valve may not be working. If that happens when you shut off your spray gun, then pump is dead heading, stopping the motor. If this is the case it stops dead, not coasting. Either replace the pressure adjusting relief valve or remove it, and disassemble it and clean it.

STARTS AND RUNS FINE BUT WHEN I START WASHING IT QUITS SPRAYING AND THEN BUILDS PRESSURE AND KILLS ENGINE


The reason it stops spraying might be a clogged gun, hose or nozzle-tip.
The reason for pressure buildup killing the engine might be a stuck unloader valve in the pump.

While you are checking each component of the "output" side, spray some penetrating lube into the "input" side of the pump (where the garden hose connects) and let it be working on the unloader valve.

Fix the spraying problem first:
Start at the nozzle and verify that it is open by using low-pressure air. Clean or replace as needed. Next check the hose (with nozzle and gun unhooked) and finally the gun/trigger mechanism.
All must be clear and open to perform correctly.

Next, pour a few ounces of power steering fluid (or similarly LIGHT oil) into the garden hose, attach it to the pump and turn on the water supply.

Leave the "output" hose, gun, etc. UNHOOKED and point the output port of the pump (where the high-pressure hose connects) towards a vacant, safe area.
Startup the engine and allow the oil in the garden hose to work its way thru. (About 1 -3 minutes of run-time.) Shut it down and attach the high-pressure hose.
Hope this solves the problem!

Are you putting the soap nozzle on the end? Either that or depending on what type of nozzle you have, some times you pull out or push in the nozzle to switch it to soap.

There has to be no pressure to draw the soap, so you either have to put in the soap nozzle in, or if it has an adjustable end, set it to soap by pushing or pulling.

You cannot spray high pressure with soap unless your unit is equipped with another siphon hose for pressure soap.
