Check the suction line for leaks. It needs constant water
supply to build a constant water pressure. You may also
check the pressure regulator for leaks. You may also
check the carbide or ceramic pistons for breaks. Send you e-mail for further assistance.

Karcher hds 558c after about 15mins looses pressure, then about 30 seconds later pure stream come out

Sounds like water is not getting to the pump for some reason. As the pump needs constant water flowing through it for cooling, you should not operate the unit until you find the problem. The pump could be damaged.

How to rebuild High pressure pump

You can get a repair or rebuild kit for this pump at any store that sells Karcher. You need to have a torque wrench and a set of picks to remove the packing. Take the head off the pump and pull the packing and the valves. Replace them as the instructions show and then put the head back on.

Check the pump. If it's turning you should have pressure unless the pump is leaking . Look it over closely.

My Karcher high pressure sprayer is delivering intermitant pressure.Every 15 seconds or so it developes high pressure for only about two seconds. Why is it not delivering a constant high pressure stream?

Check that the water supply is constant , it sounds like the pump might be pushing out more water than can be delivered , or it could be a dirty inlet filter
