Many of the models of Karcher machines, have a valve that under pressure...will compress and at the same time it will let water by-pass and circulating inside the head. As this valve compresses it also puts off a micro switch. This all happens when the gun is closed. This valve is called a SPILL VALVE or sometimes a CONTROL VALVE. Now for various reasons (example you store the machine with pressure in the system)....the seals of this Spill Valve get damaged. So you can have a problem in which the machine stays off....or a problem like yours...the machine continues running with gun closed. Your problem with gun closed...the spill Valve is not compressing and therefore not stoping the machine. At first when this happened it caused a fault also in your machine's valves. The gun was closed...pressure grew high...and this burst the intake valves for sure.
So my advice is that the spill valve must be renewed and also the intake valves. You must also check the Miro-Switch to see if it got stuck in the on position. If micro-switch is faulty, this also must be renewed. The Spill Valve is often located where you find a micro-switch holder with an electrical wire coming out. When you find this micro-switch...detach it from machine...then put on machine for a few minutes and press micro switch to see if machine stops. If machine stops...then at least Miro-Switch is OK. Always do these tests with electrical protective clothing, Shoes and Gloves!! Now if your machine does not have a micro-switch...then you have a spill valve which only by-passes water. This type of spill valve also needs checking and if need be renewed.
In a few simple words, the spill valve does all the work after one has opened or closed the gun. Sometimes by changing the spill valve only....the pressure will get back to normal. If not ...suction and delivery valves must be checked.

If it's leaking it obviously has a bad seal or is broken. I would try to disassemble and see if it has a seal or not. Sounds like you could have a bad "O" Ring or some other type of seal leaking but I'd bet on an "0" Ring damaged or wore out. Dissemble it and see what is sealing it and proceed accordingly.
