Question about Karcher Pressure Washer Gun 91120200 91120200

Open Question

I tried to repair my karcher spray gun. I have a small spring and a small white plastic piece which the spring fits onto to find a home for. I'm sure its to do with the trigger handle but I can't see where it fits. Can you help, a diagram would be helpful.

Most Karcher guns I have worked on have had a spring behind valve between hose pipe inside gun.

SOURCE: trigger gun

It sounds like you left out the spring in the hose.
There are about 10 different models of K330 with several types of guns. Go here and search until you find the correct gun so you can see the diagram. I think it will be hard to buy a replacement spring, though.

SOURCE: karcher 1650 leaking water from trigger

i believe the spring is the actual trigger spring that pushes the trigger switch back in place and the water leaking out is probably a seal issue

Will a T50 patio washer connector pipe, fit to a karcher 111A pressure washer gun?

Some gun and wand pieces may be interchangeable among different brands. Like lawn mowers, even though there are quite a few different brands/labels, they are made in the same factory.

Where can i buy repair parts?

Find a pressure washer vender in the yellow pages. It doesn't have to be a karcher dealer. Take it to them and show them what you are trying to accomplish. They can usually set you up with generic parts that will work just as well or better. Parts like hoses, trigger guns, lances, spray nozzles etc are really generic anyway. That's why there are no part numbers.

Also, stores like Home Depot, Lowes, Sears etc usually maintain a small section with these generic bits n pieces. I hope this is helpful to you and gets you pointed in the right direction! And good luck! Rate me if it has helped you. Thanks!

Karcher 2400: Won't stop spraying.

Dear sdadean,
I am assuming that when you said "wand" you mean the "gun". Myself I rarely service guns. But there are types that are serviceable and others that are not. If the brass elbow had 2 stainless steel pins....then this is a gun that you must replace with a new one. And putting oil, is the worst enemy....because oil damages O rings. Now the high pressure hose is fitted inside the brass part by being sealed by a black O ring and a white backing flat O ring. I do not know if these that you saw. Now if the brass has only one pin coming out from the back, this type of gun can be serviceable. Look at the brass at the place where the lance is attached. If you see a hexagon hole, this is a plug that can be unscrewed with an allen key. Behind the plug there is a ceramic seating. Then you find the valve and a spring. If the steel valve and the ceramic seating are damaged, the whole gun must be replaced.
To tell you the truth I usually change the gun and fit a new one, when the machine keeps on going because the gun does not close. I find it the best and the most safe way of solving the problem.

Can't get the spray gun onto the hose from the manual

Your posting is incomplete, so I'm not quite sure what we're dealing with here.  I understand the machine and the high-pressure hose are Karcher - right?  Is the gun also a Karcher part?  If all are Karcher parts, they should fit unless the screw threads have been damaged.  If they are not all Karcher parts, they will not fit because Karcher connectors are different from almost all others.
Please post again if this doesn't help, giving as much detail as possible, and I'll see what else I can offer.

I just had to repair one of these guns for work. It's a bit tricky, seeing as you are dealing with springs and such...but it can be done. Take your time ...don't set the springs until you have things set in place and lined up. Make sure the pins are in place. Set the flat spring first (it is the toughest) while the handle is depressed all the way in. Gently open the handle and then set the torsion spring. Take your time here...springs are set and they could make all the pieces fly out if you don't quickly get the other half put on it. Hope this helps.8d59edb.jpg
