Most pressure washers when their gun is released, the machine stops automaticaly. This is done ny means of a control valve. When the gun is closed...pressure is built and the control valve moves and switches a micro switch off. In your case the micro switch is still closed in off position. Now this happens if a machine is left and stored with pressure in it., This control valve could get jammed and leaving the micro switch in off position. It could also stay in off position by sticking, due to incorrect chemical.
So the control valve or even called spill valve, must be renewed.
Sometimes a little lubrication with the right type of silicon grease will get the control valve working again. This job is sometimes delicate and better done by a qualified technician.

hi mark, you do have a problem with the lance.
you need to disconnect the lance and straighten a paper clip and insert down the nozzle end.
use the machine to wash the dirt in the nozzle backward down the lance.
Dirt only in nozzle end.
if still no good, purchase some nozzle cleaners and file out nozzle very slightly.

I assume you have run some water through the supply hose before connecting it up, they don't like pumping air. The most likely problem is a blockage at the inline filter where the supply hose enters the unit. If there is no filter there then the problem may be more serious. Grit may have entered the pump and worn out the pistons and then you may as well buy a new one because it won't be worth repairing.

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
Make sure you have bled all air from the system. Also make sure you have sufficient water supply; if house water pressure is too low or if your hose is too long or doesn't allow full flow, you may not be getting enough water to the unit.
