Hy does water squirt out around the nozzel


Inside the nozzel, where the tip locks in, there is a groove for an o-ring. If that o-ring is missing, water will leak around the tip as you describe. Sometimes when the tip isn't fully seated in the nozzel and you pull the trigger, the tip goes flying out. The o-ring will fly out also. Most people find the tip but never see the o-ring. The o-ring is usually carried by any company or store that carries pressure washers.

Black and decker electric power washer nothing coming out of wand all water coming out trigger.


Either the pressure tip or wand are blocked or the valve in the trigger is broken. Remove the high pressure tip and either try another tip or pull the trigger without a tip on the wand to see if you have the same problem. If available, try another pressure gun on the hose.

As soon as I turn the water on, it comes out of the gun and high pressure turbo wand even with the machine off. I used it yesterday with no problems. It does this without even pressing the trigger. ...


Hello,
This part should be available from the manufacture, have you check their website. It is normal when you turn the water on for a small string of water to come out the gun when you press the trigger even when the engine is not running.
Thanks

I have a B&K kitchen faucet (LM#203120) in my 2005 Newmar motor home. The spray wand has recently broken. The spray wand is approximately 6.5 inchs long and is connected to the water line by means...


If you are talking about the standard spray nozzel with trigger type control than replacement sprayers are reaidily available. You should be able to unscrew flex hose from nozzel at the base of nozzel where sprayer goes into holder on sink.There should be ribbed section on sprayer where flex hose goes in. Grip that section and turn upper section of sprayer counterclockwise to remove. Most hardware stores will have replacement nozzels for under ten dollars. Hope this helps. Thanks

New Troy-Bilt 3000 psi - Very Hard to Hot Start


When you run the unit and shut if off, release the pressure from the spray wand before trying to restart the engine. This built up pressure will cause it to be very hard to start as you have found out. If it does not start on the second pull release the pressure again. Another option is do do what I did on mine. I simply put a pull tie on the handle so I can pull the trigger back and use the pull tie to hold the trigger open. Make sure if you do this, that you remove the high pressure orifice from the end of the wand before attempting to start the engine. Otherwise the pressure will come on abruptly and could injure you or do property damage.

Power washer loses pressure. Engine runs fine. Taking the nozzel off, squeezing the trigger, and then putting the nozzel back on sometimes remedies the problem. How do I fix it? Thank you.


Your bypass valve is jamming. All you do is take it out, put a smear of o ring grease around the o rings then put back in, make sure you push it all the way in and should fix the problem.

Lack of pressure after releasing the trigger on the wand


Hello awcockerill:
This sounds like the bypass (unloader) valve is sticking. Here is a diagram of your machine's pump. On page 2.4 see part #1. The top of this assembly is a black plastic cover. Remove all of assembly # 1 carefully. Under that is part #8. This is the bypass valve. You need to pull this out, check that the o-rings are not bent, worn or damaged, then lube it good with a VERY VERY good waterproof grease. Re-assemble it and all should be well. The part numbers are on the diagram but where to get them depends on were you live. Karcher web site may give you a number to call. Good luck.

When garden hose is connected to the pressure washer no water comes out of the wand, engine is off.


Dear radcongirl,
Try removing the high pressure hose from the machine. Then connect the water hose and see if water comes out of the outlet.( you can also try this by putting on the machine for a few seconds). If water comes out of the outlet, then you have a problem in the high pressure hose or the wand and trigger. Check also the lance and nozzel for blockage.
I do not know what kind or model of machine you have, but most machines the water always comes out of the outlet when water is fed to the inlet. In bigger machines this cannot happen because they have a reserve tank.
Regards,
Fulltech.

Pressure washer lacks pressure initially?


Dear allbusiness9,
This problem is most probably due to a faulty Spill Valve( also called Control Valve). When the gun is released the spill valve is compressed and it either closes a micro switch or just opens from the bottom and keeps the water circulating. All spill valves keep the water circulating from the bottom part. Now when the gun is pulled (opened)...the spill valve extends and closes the bottom part, and thus water goes out of the nozzel. When you work with no nozzel, there is enough water flow to close the bottom part of the spill valve. So when the nozzel is placed back there is no chance that the bottom part leaks water. When the gun is started with the nozzel....the bottom part of a FAULTY spill valve,..will colapse and pressure drops. So to fix the fault you must change the Spill Valve. In some occasions, I also found that suction valves give this problem. A faulty sucktion valve will colapse under high pressure, and lets water pass the other way round.
But in my opinion and experience, your problem is in the Spill Valve.
Regards,
Fulltech.

Pressure washer stalls out when wand nozzle is released


common for not starting unless trigger engaged as you are turning the pump as well as engine creating pressure,as for stalling pump has unloader valve which is probably in need of grease(use good silicone grease)this allows water to ciculate when trigger released.
