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

Hi, I have a Karcher K2.400 Electric High Pressure Washer. When I pull the handle nothing happens. When I plug the power in the pump does run a few seconds. I also checked the inline filter and that is all...


There is a pressure switch that turns off the pump when it gets to a certain pressure. It sounds like that switch is sticking. The contacts should be closed when you first turn on the pump. If you hold open the trigger when you first turn on the pump and the pump stays on then that pressure switch is most likely the problem. If you turn on the pump with the trigger open and the pump runs for a few seconds and then turns off check for a blocked nozzle.

What is this problem - Karcher 3.86 electric pressure washer: humming noise, plug gets very hot, then unit shuts down?


Your pressure washer is either not fitted with a run/stop device in which case like mine you have to switch off within a few seconds of closing the trigger. Check your model features?
The humming noise is the motor stalled out against the pump because there is nowhere for the water to go. The shutoff is caused by the safety overload switching off after overheat.
Or, it has a pressure operated run/stop which is not working. Because water and electricity don't mix, I would suggest getting more specific help. You can download Karcher manuals /spares lists online from Karcher specialists but remember electricity is the silent killer.

Pressure starts and stops


Sounds like your unloader valve is sticking. It needs to be removed and lubed with lithium grease.

The water must be switched on, and seen to be running freely from the nozzle for a few seconds before switching on the power - suggest you check the fuse in the plug, and then try the above.

Karcher 360M pressure washer pulsating problem when idleing


Hello,


unfortunately these little units have this problem commonly, 9 times out of 10 it will be the plastic head or the plastic valve block on the unit will be cracked and leaking slightly... it builds up pressure then leaks out and tries to build up the pressure again and this just reoccurs over and over...

you can get this repaired but is normally about half the cost of a new unit, if the pressure is still okay i would probably recommend just keep using it until it proper dies...

If you do get this fixed, we have studied into this and believe the main cause of heads cracking is warm water say if your inlet hose is in the sun for a period of time this can cause the water to become quite hot or if the unit sits and water trapped inside the head assy freezes can also cause this. Hope this helps Kind Regards Brad

I have a karcher 495, it is puslating when it is


It sounds like there may be a pressure leak somewhere in the system. The machine cuts off when there is no flow of water past it. If it is leaking then there is intermittent flow. Which would make the machine run then stop continuously.

Karcher Pressure washer


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.
