Dear, cb_scherer,
I can only give you some hints because I do not know the type and model of gun. First if your gun is put together with rivets and not screws, this could not be serviced. In this case you have to buy a new one. Now if you have screws, normaly Torx(T15) or sometimes Philips....you can open the gun to have a look inside. Some guns have an adjustment for correcting the travel of the trigger. This is a simple alen screw. Now if damage has been caused to the pin that is pushed by the trigger, then also a new gun is a must. In my opinion I rarely service guns. Infact the only guns that are serviceable ,..are of industrial machines. As I said, I do not know what type of machine you have and so I do not know the type of gun you have.
My general advice, is to buy a new gun. A gun is not that expensive. And working with a faulty gun not only in time will damage the machine, but it is also not safe!!
Regards,
Fulltech.

Not Simple.
I have the same Problem, the leak is from the seam of the Manifold or on the pressure side of the Pump and the hose housing. In my case there is a small crack in the seam of the Manifold Housing. A manufacturing defect.. A New Manifold Complete Replacement about the half the price what I paid for this pressure washer at Walmart... :( If under 1 year old, and you can find a receipt,Karcher will replace the whole Pressure washer under warranty.

Karcher electric power washer480 .pump runs on when trigger is released there are no leaks . Also i can not turn machine off at the main switch.


If you are unable to shut off the pressure from the wand, there may be an issue with the unloader valve that is stopping it from switching into bypass mode when the trigger wand is released. The unloader valve is designed to respond to the spike in pressure created when the trigger wand is released, and to divert the flow of water coming from the pump to bypass the pressure hose and flow back into the intake end of the pump. If the unloader valve fails to switch into bypass mode, water may continue to flow out of the trigger wand. This may also cause damage to the wand. If you are unable to shut off the pressure from your power washer, stop the engine and discontinue use immediately. The unloader valve should be removed and possibly replaced if found to be malfunctioning. The inability to stop the flow of high-pressure water from the wand can be dangerous and should be fixed before continuing to use the machine.

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.

My electric Karcher pressure washer does not shut off.


this can be that you need to bleed the system of air or that there is a problem with your trigger gun sticking when you release the trigger.
These are two things I would check before you go into the machine.

You did winterize the machine? Leaving water in a powerwasher will freeze and damage the pump. It's a common happening, because people don't think of it or are not told by the maker.

I started working with the Karcher KB4040 pressure washer and all was well for 1-2mins, then it sputered a bit and all power died. All hoses were still attached properly, it hadn't blown a fuse in my house...


if the water is in anyway impeded, like kink in hose the unit turns off and goes into protection mode. That it it shuts down for a pewriod of time depending on how hot it may have got.
When its rested try it again ensuring you definitely have water flow.If the solenoid has failed it costs about !60-200 to fix as they replace all seals regardless

Karcher pressure washer trigger problem


The wands that it will not run with would most likley have a little dirt in the tip of the nozzle. This would not allow the water to flow through in turn activating the pressure switch and shutting the machine down

Karcher k4.98 switching on and off


The machine has a pressure leak. Check for a cracked controll head or either a leaking outlet elbow. The machine will short cycle if the holding pressure can not be maintained

Karcher washer went dead


Dear jimbocom,
The problem is that the spill valve got stuck. When the machine is working and the gun is closed, a valve( spill valve) moves with the accumilated pressure and switches the machine off. So what happened is that when the spill valve did its job, it found no water...and remained stuck. This leaving the machine in an off position. Service and lubrication to the spill valve must be done or completely replacing with a new spill valve. In my opinion you have no serious damage, but this job must be carried out by an expirienced technician.
Regards,
MG.
