Question about Karcher Garden
The best thing is to get a complete pair of quick couplers. One male one female and replace the ones you currently have. Stick the male on the washer the female on the hose and as they are the same should be able to hold under the pressure of water.

SOURCE: karcher washer went dead
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.

On the Kärcher, you have a bayonet mount at the base of the tip end of the pistol grip. This is where you attach different types of nozzles and gadgets after having removed the existing sprayer tube. Just push in and turn a quarter of a turn, then you pull it off the pistol grip. The hose is possible to remove from the machine as well, an ordinary threaded mount but since you need the pistol grip to regulate on/off this is probably not what you want to do. If the telescopic wand is made by Kärcher it should be very easy to snap it into place just like when you removed the sprayer tube/nozzle. If the attachment was made to fit Alto washers there is an inexpensive adapter that works very well. Good luck!

SOURCE: karcher 2.56 keeps pulsing on and off whenever high pressure nozzle is attached. I have tried different nozzles and same thing is happening. when i press the lance without any attachment it works fine
If this PW has never worked properly -- it is possible that the seller sent the wrong pressure nozzles. All pressure washers have nozzles that are matched to the flow-rate and pressure of the machine. If they sent Nozzles that were really supposed to be for a machine of lower flow rate (smaller orifice nozzle) this would cause exactly the problem as you are describing it. This is because the electric motor does not have sufficient horse power to force the xxGPM out the smaller hole, so the motor surges and stalls, repeatedly.
Another possibility: Try a different electrical plug outlet. It is possible that the motor is not able to draw enough current from your plug. Sometimes older house plugs, because of the way they are installed, will not provide a good, solid 15 amp circuit like it should. As the motor comes under a load (i.e., when you install pressure nozzle) it draws more current to feed the work. So try a different plug and be sure it's on one of your circuits that is not loaded with other household items like the refrigerator, microwave oven, etc. The little washer all by itself will pull close to 15 amps, which is the max capacity of older home circuits.
Last, Look for the unloader valve. This is device that allows the water to go into a by-pass loop when the trigger is not pulled. It sounds like the unloader could be out of adjustment. Counter-clockwise will lighten the spring / Clockwise will tighten the spring. Toy with different adjustments -- ccw 1 complete revolution/test for improvement. Repeat. (it should have a plastic handle on top of it that can turn either direction. But look at it first, as there may be a "set" nut holding in one place.)
