SOURCE: Pressure washer - My water blaster does not speed up

I was mistaken in my thinking about how the pressure washer works. There is a by-pass valve that takes the load off the engine when you stop spraying. The engine actually runs at a constant RMP. When the spray is on, the by-pass valve closes and this increases the load on the engine. This is what I had been hearing as a "speeding-up" of the engine and was no longer hearing. Anyway, I took the un-loader apart and blew it out with some compressed air. It works fine now.

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

CH 1/2hp airless paint sprayer model# AL 2310 wont prime, how do i fix


Just had the same problem with the same exact unit. Here's how to fix. Turn the pressure knob fully counterclockwise. Take a 5/8's wrench and back out the pressure knob 2 full turns. Yes, the exact same knob you just reversed only get a wrench on where it connects to the unit. Run it for a minute like that. On off a couple times.Run the gun and get the air out. You should notice it working. This is per the owners manual. Good luck man.

I bought a honda pressure washer power boss 3000. I load the gasoline, start the machine, but pressure water is not coming out from the trigger. i tried so many things , but can t get started.


If you are using a water tank for water supply, remove the water supply line from the pressure washer and connect a water hose from a faucet. Turn the water on, then crank the engine. Pull the trigger of the spray gun until water comes out. When then water starts to spray properly the release the trigger, shut engine down with pressure on the line then reconnect the water supply from the tank to the pressure washer. If this fixes the problem then the problem was "air-locked"! Happens alot with new pressure washers that have never been run. If you need any other help, please email me @ davidandlisacampbell@yahoo.com

Engine runs , not getting any water flow when trigger pressed.


Disconnect hoses.
Look for kink in water hose.
Check incoming water connection for filter washer
Replace filter washer
If you don't have a filter washer, put one in.
Hook up water, and turn on
Water should come out other side of pump.
Turn on machine.
Do you get pressured water out of pump.
If no pressure, then pump is suspect
Hook up washer hose without gun
Does pressure come out of washer hose
Finally, the gun trigger may be bad.

We had to buy guns now and then.
Search for pressure washer guns
Following link shows guns we used:

Water goes thru. have hydrulic oil to level. gun semas to stick on. NOT GETTING ANY PRESSURE AT NOSSEL.


Hydraulic oil?
Is this a pressure washer?
Pump should be half full of SAE20 or SAE30 non-detergent motor oil.
Engine should have 10W30 motor oil.

If you have a pressure washer ... and not water is coming out end of gun:
Take all hoses off machine.
Look at incoming water hose connection.
The should be a filter washer.
Clean or replace filter washer.
Hook up water and turn on water.
Water should come out other side of pump.
Turn on power washer and see if water coming out of pump is pressurized.
Now hook up pressure hose without gun.
Turn on pressure washer and see if water comes out of hose and is pressurized.
Finally, the gun may be bad.
We used to replace guns when they went bad.

My pressure washer is a G 2500 oh n i have no pressure coming out, it turns on but no pressure.


Good news, your engine runs
But your pump may be bad

Here's how to test your pump
Check oil as outlined lower down
Disconnect the washer hose and gun
Connect water hose and turn on water and water should pass straight through the pump
Look for clogs in the hose-end where water hose connects to machine

Turn on machine and see if water shoots out pump
If water shoots out of pump, but no water shoots out of gun, then you may have a 'mud-dobber' wasp clog in your washer line or gun

Look for clogs in the end of each water connection.
Now connect washer hose without the gun, tun on the machine, and see if water shoots out of washer hose
Finally, the gun trigger mechanism may be bad
I don't know which gun you have ... but we replaced guns on our machine now-and-then ... google-search power washer guns for a replacement

Check your pump oil
Pump oil is SAE20 or SAE30 non-detergent motor oil
Pump should be no more than 1/2 full of oil
Use plastic hose to drain pump oil
Do not turn machine on its side or turn machine over or engine oil will run into carburetor

Cant start the unit ,there is to much pressure on the pull chord when water is hooked up.


Trying to start a pressure washer with water supply on and gun trigger off will be a difficult task. It could be comparred to trying to start a lawn mower with the mower in tall grass. Place the mower on the drive or walkway and pulling the rope to start the engine is much easier. It is easy to start your pressure washer with no water in the system however there is a remote possibility that you could overheat the seals if you take too long to turn on the water. It is a little more difficult to start the washer with water supply on and someone holding the trigger to wand open. This will prevents pressure from building and making engine hard to start. You will not damage your washer if you start it with water supply off if you flood the pump and pressure hose with water first . Here is the procedure I use if i am working alone. I trun on the water to pump and open trigger to gun to allow water to flow into pump and pressure hose. Turn off water (leaving the water supply on will make it a little harder to pull starter). Start engine while holding trigger to gun open. When engine starts release gun causing unloader to activate circulating water in pump. Now turn on water and you are ready to work. If your system is under warranty however, I would advise to use the starting procedure outlined by mfg (hold open trigger to gun however). To get the longest life from unit try using it at say 75% of capacity or lower if your can and use max pressure on the tuffest jobs. Leaving your washer at full pressure for all jobs is like driving your car at 100 mph everywhere your go. Good luck.
