Question about Honda Karcher G2400HH-R Pressure Washer

2 Answers

Karcher k2400hh pressure washer, water pressure cuts out.

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

I do not always have pressure. Water will com e out and when I do have pressure as long as I do not release the trigger it will continue to have pressure. When I let off the trigger and the press it again...


What you have is a sticking unloader or in the case of some equipment a spill valve. Depending on the machine that you have you will either need to replace or lubricate the valve. This is most common on home owner style Karcher units with the following model numbers.

K2300G 1.194-110.0
K2400HB 1.194-303.0
K2400HH 1.194-302.0
K2400HH-Q/C 1.194-301.0
K2401HH/G 1.194-305.0
K5800G-PL 1.194-104.0
K5800G 1.194-103.0, 1.194-102.0

For instructions on repairing the units with these model numbers please visit:

This will walk you through all the steps necessary to correct the problem.

How do you replace the pressure loading valves


if it is a karcher machine you will need to remove the pump, and the valves need to be removed with a set of valve pullers, karcher sell the special tool needed for this, you cant remove the inset types any other way but with the tool,

any questions just ask away

No peessure


if you have good water flow to it and you have water coming out of the lance when you pull the trigger but its not under presure then it will most likely be bad valves in the pump head or worst case a fault in the pump. any questions just ask away

No pressure. Have cleaned inflow filter, checked water supply and cleaned and lubed the uploader valve.


if there is water comming out of the back of the pump then your piston seals need replaced , if the lace vibrates then one or more pump valves are blocked ) theres 6 in total /in pairs ) , try running the machine with no hose/lance connected as the lance nozzle often blocks up /malfunctions

hope this helps , if it does please vote
