Dear Aliciaashwor,
I am assuming that the problem occurs when the gun is closed. This problem is due to a fault in the spill valve. When the gun is closed, pressure pushes this spill valve downwards and puts off a micro switch. Now this spill valve has "O" rings. If the O rings get worn out, the spill valve starts going up again and switches the machine on. The pressure is built and the spill valve goes down again to put the machine off. And so this goes on....ON OFF ON OFF. The spill valve must be changed. But if you see that you have pressure when gun is open, all you have to do to stop, is switch off the electricity before you close the gun. This can be done as much as you want, because no harm is done. So open the gun, switch on and work. To stop switch off and after close the gun.

Karcher k3.86 motor runs but has no pressure when trigger pulled, motor doesn't go faster.


Could be a pump, but most likely the unloader valve is stuck open. After replacing/repairing the valve, do the following to prevent it in the future: after finishing using it, unhook both hoses and pull the start cord on the engine several times to empty the water from the pump and valves. This is especially necessary when using hard water.

I just bought a 2nd hand honda excell psi max vr 2522 2.2 gpm max 5.5 hp gvc160. i put gas and oil and it wouldn't start?


Have a helper hold the trigger of the wand open while you try it again. If it starts that way you have a sticky unloader valve in the pump. DO NOT RELEASE the trigger for more than 10 seconds if the engine continues to strain when released! If the engine doesnt run freely when you let go of the trigger, pull it again and shut down the unit!
Add some power steering fluid to your supply hose (about 3 or 4 ounces at a time) and restart the unit with the trigger pulled. Allow the oil to flow through the pump for 1 - 2 minutes for each treatment. Several treatments should make the pump and valve happy again.

Hope this helps.

My karcher G2000QT WORKS AT HIGH PRESURE FOR A COUPLE OF SECONDS AND THEN STOPS THEN A COUPLE OF SECONDS LATER WILL START AGAIN WHATS GOING ON?


are you making the machine **** for water, if so you have got a air leak on the suction hose.
try force feeding with water by connecting your hose to the mains water hose and see if you can see a water leak.
could be starved of water also,chack the filter

Pressure is fine when first started ,if trigger released no Psi


Your uplift injector valve in the water pump is sticking. You need to remove this part. Lube the top o-ring only with a water proof grease. Reinstall this part. You will be up and running again.

You need to use needle nose vise grip tool to easily remove the valve. You need to grind down the vise grip tool to fit the opening where the valve is installed.

To prevent this problem from reoccuring use a pump guard additive.
