My honda xr2600 pressure washer stops running when i pull the trigger


check for a blocked main jet in the carby
the principle is that when the trigger is released there is no pressure in the pump so the engine is idling
when the trigger is pulled the pressure control valve closes the bypass back to the pump and so the motor is loaded up if there is a problem in the carby ,then the motor will stall

I have a honda 2600 pressure washer. After running fine for a couple of seconds the water will stop flowing out the tip. It is receiving water,but will not flow it to the pressure hose. I even disconnected...


This happens when air gets inside the hose. An air bubble of sorts is in the hose and will not build pressure until you blow the air out of the line. Start the pressure washer, turn on the water. pull the trigger on the gun. It will spitter and spatter and come to a trickle. release the trigger on the wand. Pull the trigger again and it will eventually work it self out.

Hello i have a 6 hp briggs pressure washer and it starts fine and runs for 30 seconds and shuts off. it feels like the motor gets stuck when i try to start it again, but after a half hr or so it will turn...


You have to make sure you are pressing the trigger while you start the pressure washer. You should also make sure you are releasing the pressure at least every 30 seconds or the pressure will build in the pump and the engine can stall.

If it stalls with pressure in the pump and you don't relieve it by pressing the trigger, it will be very difficult to start. The pressure will slowly bleed off over time, which sounds like what you are seeing.

This sounds like it had water left in it and it froze over the winter. The motot turning on and off signals a water leak on the output side of the pump. You may have a cracked pump housing. Locate the pump and make sure nothing is leaking in that area when under pressure. looh for fine hairline cracks.

Won't stay running


Pressure washer when you first try to start them that stop underload. We had the same type of problem with 11 hp Honda if you hold the trigger open the motor will be under less load we found by running the motor for about a minute it would work normally. Remember to make sure the water hose is turned on pull the trigger on, until water is coming out of the wand , now try and start the motor but also hold the trigger open, now you will not be building maximum pressure, after about a minute release the trigger and see if it keeps running.

NO PRessure


Hi It sounds to me like your unloader valve is stuck, this is the thing that is meant to move up and down when pressing the trigger.Please remove the unloader valve assembly and check for damage. If no damage is found then grease and lubricate this part and replace and this should work ok again.

Loud repeating noise until the water trigger is pressed


Check the pressure washer for leaks. That sound is probably the unloader valve recycling as the machine slowly looses pressure and needs to build it up again to max pressure.

Pressure Washer Engine will not stay running


My Kracher 2500 pressure washer has no pressure unless I remove the nozzle. If, I remove the nozzle and pump the trigger several times and quickly replace the nozzle it works fine until I release the trigger. Karcher (online) suggested I remove and clean the unloader which I did. It still doesn't work correctly. What another solution?

Karcher 2400 psi blaster When you release the trigger it will not pick up pressure when you use it again


To determine if your problem is due to an easily replaceable part, follow these steps:

1. Connect the water supply hose, the pressure hose, and the wand WITHOUT any nozzle tip.

2. Turn on the water supply, and press the trigger until water is smoothly running out of the nozzle
after any air is all purged out. Release the nozzle trigger.

3. Start the engine, and let it warm up for about 30 seconds.

4. With the engine running smoothly, press the nozzle trigger. The water should flow out of the nozzle (without the tip installed) at a faster rate, while the engine noticeably loads down as it used to do before your "no pressure" problem. If it does not load down, turn it OFF, and disconnect everything, and contact a Karcher repair facility.

5. If the engine does load down, release the trigger, and install one of the nozzle tips (not the black one).

6. Press the trigger, and the engine should load down, and you should have normal pressure from the wand. After you release the trigger and press it again, you will probably again have no pressure, and the engine will not load down. Removing the nozzle tip, pressing & releasing the trigger, and re-installing the tip should give you normal pressure again, but releasing the trigger will cause no pressure until you again remove the tip, press the trigger, and re-install the tip.

This is caused by a bad UNLOADER VALVE, which is located under a black cap with a metal button on it located on the top front of the pump. I don't know if you can purchase the replaceable parts from a Karcher repair shop, but when a neighbor & I took his washer to a repair place, it looked pretty simple to do this repair, and he was charged about $60 to replace a $5 (maybe) part, and it took about 5 minutes.
