Does it hold pressure at idle? (trigger released) and then hold a lower pressure with trigger pressed? If so you probably have worn or wrong size nozzle

SOURCE: I have an old kew pressure washer and when I pull

Dear dennis_partr,
In general all pressure washers have a control valve. This is sometimes refered to as the Spill Valve. When the trigger is pulled, the spill valve is in normal position. When the trigger is released, the spill valve compresses to let water circulate from its bottom part. If when the trigger is pulled and the bottom part of the spill valve does not close, then water keeps on circulating and hence no pressure. In this case change the spill valve with a new one. Also there could be a fault in the sucktion valves. If the sucktion vaves do not close, also water keeps on circulating. One also can examine the delivery valves. If these are not closing, then water is being sucked while delivering. Hence no pressure. Another cause but very rare, is that the swash plate that is pushing the pistons got loose. The electric motor will be turning, but the pistons stay in the same position.
I mentioned many causes, but usualy it is the spill valve. If with a new spill valve, there is still no pressure....then you must tackle the sucktion and then the delivery valves.
I wish to add that I assume that you have the correct lance and correct nozzel size. A worn out nozzel, will result in low prssure too.
Regards,
Fulltech.

SOURCE: 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.

Try connecting the water but hold open the trigger. While holding open the trigger, try to start the pressure washer. That works for me.

When I try to start my gas-powered pressure washer, its very hard to pull the crank and I cannot start the motor.


When everything is working correctly, and your washer has an easy start valve, (easy start valve will allow you to start the machine with-out having to hold open the trigger) the engine should pull easily. Some washers do not have easy start and you must hold open the trigger on the wand to unload the pressure in the pump. If you are holding open the valve and still have difficulty, remove the water supply and pressure hose and let out all the water. If still hard to pull most likely something has failed or pump is low/out or lubricant. If lubricant is ok, try reducing the pressure adjustment to minimun and try starting. If it is now easy to pull, problem is related to pressure regulator /unloader valve. Try adding oil to water inlet and let the oil displace out all the water within the pump and let it set for a while. Good luck

Won't stay running


Pressure washer when you first try to start them that stop underload. We had the same type of problem with 11 hp Honda if you hold the trigger open the motor will be under less load we found by running the motor for about a minute it would work normally. Remember to make sure the water hose is turned on pull the trigger on, until water is coming out of the wand , now try and start the motor but also hold the trigger open, now you will not be building maximum pressure, after about a minute release the trigger and see if it keeps running.

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.

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.

My pressure washer won't build up any pressure. it will run water when you pull the trigger, but it is the same pressure as if the unit if not running


I'll assume you have an electric rather than a gas powered unit. First check the button on the plug to be sure the GFCI hasn't popped and be sure the outlet has power. With the water faucet turned fully on and the power switch on squeeze and hold the trigger for at least 10 seconds to let the water flow push the air out and then it should start up.

No pressure


It is probably air locked....Here's what you need to do. Connect the garden hose, and HP hose, but not the gun. Turn on the water, and let it run while you make sure that there are no high points in the garden hose that can trap air....Work the hose so that any air is displaced through the pressure washer. Continue in this manner through the HP hose. Shut off the water and connect the gun. Turn the hose back on, and operate the gun for several minutes, pulling the trigger and releasing. This alternately allows the water pressure to build up on house pressure and then to depressure, pulling residual air from the system. Release the trigger, and start the machine. Usually, this is enough to get full washing pressure. If it is very difficult to start, you can hold the trigger down on the gun and pull the start cord at the same time. Holding the trigger down acts as an unloader, making the starting easier.
Hope that this helps, --W/D-- please feel free to rate this solution! Thanx!
