SOURCE: How do you clean the unloader valve on a power washer pump?

The unloader valve usually is replaced. I dont know if you can get o-rings for it. But if you want to take it apart, there will be a crown or cap style nut just below the spring. Unscrew it completely and you will be able to remove the spool. There is just a series of o-rings on it.

SOURCE: clean and unloader valve on Karcher hd3500

Hi:
Cleaning it is not enough. You need to make sure the o-rings are in good shape and grease it with a very very good waterproof grease. Here is a schematic of the pump. The unloader is parts 7 to 13 on D-2

HOW TO CLEAN UNLOADER VALVE


Good luck. It is best to get the repair kit for your unloader. Many unloaders are not marked very well and it is difficult to find the kit needed. They have all of the parts that need replacing. ( usually a new ball or two, seats, o-rings and seals) The kits usually have a diagram of what goes where. You might want to make your own drawing and match each part you take out with the part in the kit and where it goes. It is amazing how they all look the same when they are out of the unloader. Did this go here or there????

Craftsman Pressure Washer stalls out when trigger is released


Pressure unloader is stuck in closed position. Have to know what type of unloader it has to see how to get to the "ball" check. Probably rusted to the seat. Might have to replace the seat, orings and ball.

Not sprayer engine stop


This is an indication that the unloader not working properly. When you release the trigger the unloader senses the increase in pressure and bypasses the water into the water inlet. When the unloader is not working and you release the trigger, the water pressure builds quickly and overcomes the power of the engine shutting it down. Here is the manual for your machine, http://www.pressurewashersdirect.com/manuals/Simpson_WaterBlaster%20manual_2.pdf

and some information about troubleshooting from the manual.
"Not Unloading. Leak in Gunvalve or Hose. Repair gun leak . Replace leaking or broken hoses. Debris or wear in Check Valve. Remove Check Valve parts and clean. Check O-Ring. Reface with emery cloth, or replace checkvalve. Damaged Piston U-Cup. Rebuild Unloader Valve (Service Center)."
Usually when the unloader fails the pressure regulator will most likely need to be replaced as the unloader is usually incorporated within. For now try lowering the pressure some and just tie the trigger open untill you can service. Good luck.

I think your main problem is that the unloader valve needs to be lubricated. Use the very best water resistant bearing grease you can find. If you can e-mail me a pic of your unloader assembly I can try to explain how to set it up. firehead@roges.com

Where is the unloader valve on my pressure washer


is not necessarily a cap, but could be a screw in plug, that should be close to the hose hook-up on the pump Inside there there should be a round ball and a spring that you can tighten or loosen to adjust the unloader and if it has been used ALOT, where the ball seats there could be grooves cut in there and you might need to get a valve kit to fix it
