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.
Jim
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
Thanks to everyone for there advise. I removed the pump & pressure relief valve cover & poured brake fluid into valve cavity& let it soak for several hours. I still could not get the valve out so I put everything back together & it now works good. Jim

Thanks Ed, the pressure washer is working fine now so if its not broke don't fix it, but if it fails again I will try your procedure.
Thanks again Jim
