You should put 'locktite' on the male thread and screw it in all the way and lock it there. That is how it works ,the spring keeps the valve at the bottom closed during high pressure operation. When the gun is released the part with the o-ring is forced down resulting in the valve opening and then the pressure is by-passed.Those dont normally give trouble. Look for a blocked nozzle or a restriction somewhere in your high pressure hose.

Another name for bypass or unloader valve. This is a safety device for your pump head for when the pressure gets too great or water temp too hot they are pre set to dump water and prevent damage to the internal valves and seals hope this helps!

What is a bypass unloader


According to epowerwash.com:
"The unloader valve diverts water flow into bypass when the trigger gun valve is closed. Unloaders may be designed to respond to either an increase in pressure or a change in flow. The unloader valve may also be used for variable pressure adjustment."

Pressure off and on every few seconds with my karcher 3000BH


hi there rjcomer2

here is web site for parts
http://www.ereplacementparts.com/karcher-2500-11944010-pressure-washer-parts-c-33388_33389_33973.html

sounds like you have a unloader valve problem or a crack in the pressure manifold housing between pressure outlet and unloader valve assy allowing unloader to cycle on/ off

or some dirt trapped in the unloader valve seat , make sure you have good supply of water - ie good flow from tap to pump

try cleaning unloader 1st and fitting in line tap filter

hope it helps

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.

Karcher G2600 VH - low water pressure


If the spill valve activates is "spills" water under the washer. There is a restriction or the pump has become inefficient and will not pump the volume and pressure it should at full RPM.

No pressure / Karcher G 2400 HH


Hi ruthkapres:
Here is a diagram. The unloader/spill valve is #12 on page D2 or F2 depending on your model. You must pull it out, inspect the o-rings for dents or tears and make sure the valve is lubricated with a good water proof lubricant.

How to clean unloader valve..


The Karcher K2400HH and G2400HH do not have an unloader valve, they have a spill valve which is located under the black cap on top of the pump.

The spill valve needs to be removed and the side walls of the hole it sits in need to be wire brushed to remove deposits. then you can put it back in and put the pump back together.
