Question about Alfred Karcher K2400HH 5 Hp 2.5 Gpm @ 2400 Psi Gas Pressure Washer

1 Answer

Occasionly I will get pressure for as long as I hold the trigger

But if I let off the trigger I will not get any pressure the next time I pull the trigger. I have taken the pump apart and cleaned it and checked all the valves except the upper most (looks like a relief valve) which I don't know how to take apart. I have cleaned the intake filter which had quite a bit of calcium deposit. What could be causing this problem.

My water pressure does not hold the pressure when i pull the trigger


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

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.

Stanley bostitch double fires. It is an older stick feed. Works fine when I hold the trigger and tap the tip. But when I press the gun into the wood and pull the trigger it double fires. Gun is older, but...


You did not list your model number, however most bostitch nailers use the tva6 trigger valve. As this valve wears it will be erratic. Examine the firing pin that makes contact with trigger. If it looks worn or wabbles from side to side, then time to replace. To remove valve first remove trigger by removing roll with 3MM punch. Next remove one or two roll pins just above the valve, also 3mm. With roll pins removed air pressure will pop out valve. Be carefull because valve can come out with force, use glove or rag to catch. Parts available at www.toolpartsdirect.com, or generic valve at www.ebay.com. 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.

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.

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!

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.
