Karcher G2400HH-R Pressure Washer
I have a 1999 karcher K2400HH pressure washer & the water pressure cuts off. I replaced the pressure relief valve last year & it worked good for awhile, but started cutting out again. I cannot get the valve out, it appears to be stuck & there’s a tray above it so can,t get a straight up pull with a needle nose vise grip. I want to remove the pump & I need to know If I need any seals or gaskets or a pump puller.
Also where can I get a parts & repair manual for this model pressure washer?
Thank You in advance for any helpful advise.

Hello cikanek:
Try this:
From your posting, I assume you have removed the splash cap and the nylon bypass valve cover. Connect the water supply to the pump and connect the high pressure hose and wand to the pump outlet. Wad up a small towel and place it over the bypass valve opening to catch the valve insert when it pops out. With the engine throttle closed, pull the starter cord several times to see it the valve insert will pop out. If it doesn’t come out after two or three pulls, set the throttle to low and start the engine. I have performed this procedure a number of times and the valve insert always pops out. There is no real danger of the valve parts getting seriously airborn since the actual pump output volume is very low (2.5 Gal/min).
Good luck,
Ed

Problem: The pressure washer cuts out.
If your machine cuts out occasionally, it could be because you are using an electric extension cable. Extension cables must always be 13 amp constant rating and no longer than 10 metres. Please check your operating instructions for correct specifications.
There could be small leaks, holes, or tears in your garden hose or high-pressure hose that are causing your pressure washer to lose pressure when you pull the trigger. If you find leaks, plug the holes or replace the hose, which should solve your pressure issues.
The number one cause of low or no pressure when using a pressure washer is a blocked or worn nozzle. Blocked nozzles will prevent water from escaping, while a worn nozzle will allow too much water to pass through, causing the pressure to drop.
If you are hurt by a pressure washer:
Remove any object that is in the way of caring for the wound. Put pressure on the wound with a clean cloth to stop bleeding. After bleeding has stopped, pour bottled or clean running water over the wound. Gently clean around the wound with soap and clean water.
Water leaking from a loose connection can cause the unit to cycle on and off. Verify if the pressure hose has an O-ring at the connection. If missing, this will also cause the unit to cycle on and off. While the unit is running look for any water leaks that may cause the unit to turn back on.
A clogged or improperly sized filter reduces the amount of liquid to the pump inlet, which can cause cavitation and even severe pump damage. Reduced inlet flow results in reduced flow to the system, which works to reduce system pressure as there is less resistance to the lower flow being produced.
PLEASE NOTE: You should always press the RESET button on the GFCI before using the pressure washer.
The simple answer is yes, pressure washers can overheat. This is not unique to pressure washing machines – anything with a motor or power source can overheat in the right (or perhaps, wrong) circumstances.

No pressure Pump reassembly. I purchased a new pump and installed it. Got machine back together and I’m not getting any pressure. What would be the signs if I don’t have the shaft key in properly? Or any other suggestions?

Unit pressurizes then unloads over and over again with green tip, with red works perectly
Soap feed The soap feed hose on my Karcher 2650 does not suck up the soap into the washer. I pulled off the connector piece that the hose is connected to. I can blow through the hose. There is a little metal finger thing that you can tell pushes up into place when the water pressure is high. It seems like it is supposed to drop down and allow some soap through when the water is running. I found a loose(attached to nothing) gasket, looks like a little donut. It was just free floating in there. I’m thinking it may go over the finger mechanism. I just put it back on top of the finger, like a halo and put the screw in piece back in. Anyway, if you know, let me know how all that goes together.

1750 psi Electric Pressure Washer: My pressure washer is losing pressure and is pulsa…
ANSWER : If the pressure washer is pulsating then that is a sign of check valve failure. You may be able to clean of replace the check valves. Replacing the head is the wrong way to go. This is completely unnecessary. If you can tell me the model number of your pressure washer then I can assist you better in pointing you in the right direction.
