Well firstly disconnect the gun by unscrewing the hose at the pump side. see if water is avctually running out of this line. If it is the there is a blockage in the gun If now water isw flowing when the unit riuns without the gun then the blockage is in the pump outlet

Honda 160 homelite pressure washer 2700 psi no pressure


Water comes out the nozzle, but low pressure? ( more than when the motor is not running)
I would check the check valves and the unloader.
If the amount of water coming out the nozzle is the same when the motor is running or not running.
Either the key that connects the motor shaft to the pump shaft is sheared, or the pump is trash.
No water comes out the nozzle would indicate a clogged inlet filter or blockage at the gun valve or nozzle.

I have a honda 2600 pressure washer. After running fine for a couple of seconds the water will stop flowing out the tip. It is receiving water,but will not flow it to the pressure hose. I even disconnected...


This happens when air gets inside the hose. An air bubble of sorts is in the hose and will not build pressure until you blow the air out of the line. Start the pressure washer, turn on the water. pull the trigger on the gun. It will spitter and spatter and come to a trickle. release the trigger on the wand. Pull the trigger again and it will eventually work it self out.

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.

I have a Husky gasoline pressure washer. The honda motor starts but stalls because the pressure by-pass (not the right term) doesn't seem to open and builds up pressure. I haven't tried to remove any parts...


I think you're right about the knob, but try this:
Open the water to the washer. Leave the line open, and hold the trigger down to get all of the air out of the supply and discharge lines. While still holding the trigger down on the spray gun, crank the engine. This works in effect, like a pressure by-pass, and may free up the bypass valve. If you let off of the trigger, you may have a problem getting your flow back if the bypass is still stuck. You can repeat the above process and perform your work.

Take hose and gun off pump.
Start engine.
See if pressure comes out of pump.
Next, remove water hose and look at filter washer.
Clean or replace filter washer.
Turn on water and it should come out of pump on other side.

Sometimes the problems happen because the gun lever is bad.
Hook up hose but not the gun
See if pressure comes out hous.
These steps will tell you if problem is gun or hose.

I bought this about 2 months ago i have used it twice in the middle of rinsing my truck off the high pressure got really faint now it is not spraying hard at all what could be going wrong


We had problems like that before with our power washer. The pumps go bad. Even on new equipment. What's your warranty look like?

Another thing is the water gets stopped up.
Remove gun and hose.
Turn on machine and see if you get full pressure shooting out of pump.
Next, check the incoming water line.
Most power washers have a screen washer >>> replace screen washer, then fire up again without hose attached.
Gun triggers also fail. I think we had to replace guns when they went bad.
As a rule, I always read the manual front and back.
There are interesting things in the manual that neither of us know right now.
The manual may give you a hint.

If you need more help, answer back and I will look up the manual if available and see if together we can troubleshoot the problem further.

No pressure!!


You have an air lock. Here's how to fix it:
1. Connect the hoses, and turn the water on. Work the supply hose in such a manner as to displace any air in high points in the hose through the pump. Let the water run for several minutes, then connect the gum. Turn the water back on and let the PW come up to 'house' pressure, and pull the trigger to depressure the system rapidly. This displaces any trapped air. Do this several times, until you get no traces of air at the gun. Crank the PW; it should come up on full discharge pressure. If it does not, shut the engine off, and repeat the displacement maneuver. This time, start the engine while holding the trigger of the gun down. This will act as an unloader, and should give you full pressure.

2-yr old troy-bilt pressure washer with honda gcv160 engine. seems to run well, but when trigger is pulled get full pressure for less than 5 seconds before reducing to house water pressure. when left...


It sounds like an air lock. Try this: With the machine off, connect the hose to the washer and let it run for several minutes to get all of the air out of the hose, and to purge any air out of the pump. Shut off the water, and connect the high pressure hose, but not the gun. Let the water run for several minutes. stretch out the HP hose and make sure that the air is displaced. Shut off the water, connect the gun, and purge as before. Now crank it washer up. As quickly as safe to do so, open the trigger to keep water moving through the washer. It should come up on pressure very quickly. It is better during normal operation to keep water moving through the system. When I am through for a while, I shut down my washer, but leave the trigger depressed to allow the pump to stay full of water, and cool. This prevents further problems when I restart it.
Hope this was useful.
