Not sure I understand. What is your model #.
pressure is created by forcing the water through the tiny hole in the spray nozzle. The gun is a simple open and close valve.

Make sure all of the water is bleed out of it buy holding trigger down with motor not running until theres is not more bubbles or air that comes out..Make sure where the inlet for waters screen is not plugged..You may have to back flush washer to clean out or to unstick the pressure valve..Hope this helps you and have a great day

SOURCE: builds up to much pressure in hose and stalls engine

Sounds like the unloader is not working. try replacing it and see if that helps.

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.

Derek, Hi and welcome to FixYa. I am Kelly.

I just now happened across your post and note it is 3 months old. Hopefully you already have the problem solved.

If not.. looking at the pump history of having the un-loader valve replaced it sure seems that the current un-loader valve is sticking. When an un-loader valve is removed the internal housing is sanded smooth and everything about the un-loader valve is coated with Lubriplate #105 White Grease. I get the feeling that who ever did the un-loader valve repair failed to sand / clean the housing and use White Grease for the final assembly.

You should remove the valve... Sand the housing and get some Lubriplate #105 white grease (auto parts store) in a tube. Lubricate it liberally and reassemble it. If should work fine after that.

Thanks for choosing FixYa,
Kelly

What is a bypass unloader


According to epowerwash.com:
"The unloader valve diverts water flow into bypass when the trigger gun valve is closed. Unloaders may be designed to respond to either an increase in pressure or a change in flow. The unloader valve may also be used for variable pressure adjustment."

Hello there.

If the washer is loosing pressure then it needs to be looked at under warranty, im not sure where the fault would be, but another expert may well know.

If you don't get any suggestions then i would take it back and ask for a replacement or repair.

Hope this helps.

Your water inlet may be stopped up. Whether this model only has a screened hose washer or a better filter, pay special attention to that. Be sure the pathway is free and clear.

Take each of poppet valves and while pushing (with a pencil or something) on the part that moves up and the spring pushes it back down - with magnification and lots of light, be sure there isn't a small piece of debris affecting one of those valves. Its easy to miss, so look very closely.

Next, remove the hose from the pump. We are by-passing the entire unit that includes pressure hose, trigger gun, lance, spray nozzle. If it seems to pump a lot of water out of the pump--then the problem is most likely the trigger gun is clogged or the pressure nozzle is clogged. Some trigger guns can be taken apart -- some, not so much. Same with nozzles.

I hope this helps you, Randell. If yes, please take a sec to rate me. Thanks!

My tahoe willonly start in the morning if I prime carb & now not at all


The first thing you need to check is fuel pressure with a fuel pressure gauge. You need a minimum of 56 PSI (preferable a lot more) for the vehicle to start.

If fuel pressure is low than the pump is usually the problem.

The CPI injection has poppet valves that deliver the fuel to the back of the intake valves. The poppets require the minimum fuel pressure to open. If the pressure is off by less than a couple of pounds the poppets will not open.

Priming to get the vehicle started and then the vehicle continues to run is a classic symptom for this problem. Since the poppets are under vacuum with the engine running they require less pressure to open.

Dear, cb_scherer,
I can only give you some hints because I do not know the type and model of gun. First if your gun is put together with rivets and not screws, this could not be serviced. In this case you have to buy a new one. Now if you have screws, normaly Torx(T15) or sometimes Philips....you can open the gun to have a look inside. Some guns have an adjustment for correcting the travel of the trigger. This is a simple alen screw. Now if damage has been caused to the pin that is pushed by the trigger, then also a new gun is a must. In my opinion I rarely service guns. Infact the only guns that are serviceable ,..are of industrial machines. As I said, I do not know what type of machine you have and so I do not know the type of gun you have.
My general advice, is to buy a new gun. A gun is not that expensive. And working with a faulty gun not only in time will damage the machine, but it is also not safe!!
Regards,
Fulltech.

These units have pressure valves that automatically turn off the pump once the pressure is high enough. The pressure switches do fail and sometimes stick and act as you've described.
