SOURCE: karcher k2400hh pressure washer, water pressure cuts out.

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

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

Lost pressure let handle go spits out 1 second of pressure then no pressure


What you are describing is an unloader valve failure. The unloader valve (also called a spill valve or safety pressure relief valve) is sticking in what is known as bypass. Your pump is able to build pressure but when the trigger is squeezed, rather than directing the flow up to the nozzle it is looping the pressure back through the pump as it does when you release the trigger. Depending on the specific brand and model you will need to either replace the unloader or lubricate it if it is a Karcher with a spill valve. If it is a Karcher there is a known issue with the following models:

K2300G1
K2400HB
K2400HH
K2401HH
K5800G
K5800G

All of these have an issue where the spill valve sticks and will need to be lubricated with Vaseline or lithium grease. You can view a guide for this process at http://www.landanorthwest.com/dms. Select Maintenance/Karcher/Pressure Washers/All/Spill valve lubrication.

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 pressure,but some times have hi pressure, but just for a few seconds. The person before me had the machine without been used for long time now has this problem. only had pressure for 2 times than...


First if you have a filter where the water is coming into machine and if you have not already cleaned the filter clean it,but i'm sure you have already thought of that after that the pump may have a problem, most of the time it is cheaper to buy anouther machine than to fix it...sorry

Hi
don't know if this will help, but when I use mine, to start the pressure up I have to turn the nozzle to fine spray then turn it to the power spray and it works every time, shouldn't have to do this but I got it for nothing.
