These units have pressure valves that automatically turn off the pump once the pressure is high enough. The pressure switches do fail and sometimes stick and act as you've described.

High pressure won't return when triggered


If you unplug the tip, will it work? If so, unloader valve is sticking.

Karcher K2.36 motor cut out and won't restart


Yes, the water should be turned on first but if it only ran for a minute or two it should be OK. Most late model pressure washers have an automatic shutoff when the trigger on the wand is released. Turn on the water and then the machine and then squeeze the trigger on the handle of the wand and the motor should start as soon as the air is cleared from the line by the flowing water (about 10 seconds). If the unit was put away wet last season you may need to clean the nozzle with a piece of wire too.

Karcher k1 leaking from inside casing.


The most likely issue, which seems to occur alot with karcher, is a cracked water pump. What happens is that as you release the trigger on the handle, the rise in pressure should cut off the motor, but as it also cuts off the water flow at the wand end and the motor spins a few more revs until it stops, then there is a huge pressure glitch which blows apart the weak plastic pumps that they use. Since the plastic cracks it is very difficult to repair and the only option is to go and buy another. BUT...this time tape up the trigger on the handle so it is always on and then it won't blow itself up. Just use the unit on/off switch to turn the motor on and off.

Lack of pressure after releasing the trigger on the wand


Hello awcockerill:
This sounds like the bypass (unloader) valve is sticking. Here is a diagram of your machine's pump. On page 2.4 see part #1. The top of this assembly is a black plastic cover. Remove all of assembly # 1 carefully. Under that is part #8. This is the bypass valve. You need to pull this out, check that the o-rings are not bent, worn or damaged, then lube it good with a VERY VERY good waterproof grease. Re-assemble it and all should be well. The part numbers are on the diagram but where to get them depends on were you live. Karcher web site may give you a number to call. Good luck.

Pressure Washer Engine will not stay running


My Kracher 2500 pressure washer has no pressure unless I remove the nozzle. If, I remove the nozzle and pump the trigger several times and quickly replace the nozzle it works fine until I release the trigger. Karcher (online) suggested I remove and clean the unloader which I did. It still doesn't work correctly. What another solution?

Karcher Power Washer that surges up and down with water pressure.


Before you start it up:
1. Disconnect the high pressure hose 2. Connect the water supply and turn on 3. Make sure water is flowing through the pump
Start the motor, run for about 10 seconds and then turn off.
Turn off the water supply, connect the high pressure hose, turn water back on, start the motor and away you go.

No water coming through pump at all.


Is the tip/nozzle clean? try a different one. But you're probably right about the pump (I think they are all junk) unless you spend over a grand and get a "real" one
