Sounds as if you have a pump problem. your best bet is to go online to maker or a dealer near you for service help.you may wind up having to replace pump.

Karcher k 5.700 very low presure and how to fix it thanks


1 water inlet filter clean ?? not limed or ??
2 nozzle clean.
3 pressure control valve properly screwed
Sometimes water hoses are provided with a slot at the hose connection with an internal water seal, which is the wrong way to the water tap instead of to the machine

Low presure


sometimes the water pressure from the house is insufficient, when it happened to me it would run weird. The water would come out in spurts because little water would come out of the water hose. You could try and lower the pressure on the machine to compensate for the lack of pressure going in, that's all I can think of.

New rotary nozzle will not work. will spin and then stop and repeats.


By rotary nozzle do you mean the dirt blaster? or a different accessory? if it is the dirt blaster it could be that there is air in the system. take the dirt blaster lance off, then pull the trigger with high pressure untill you get a complete flow of water. then put the dirt blaster onit should work.

Another thing that could have happened is if you have bought the wrong dirt blaster for your machine as there are different types for different models.

My Karcher KB 9030 has lost pressure and is hunting when no demand water supply is plenty


In most cases the water lines can have leaks that bring bring in air and so the pressure will be less. Power off the washer and let the water flow without any air bubbles. If you seen bubbles then recheck the joints.Check the same with the outlet.
If not there is fault on the main pressure pump.

It's a Karcher presure washer K2.54, one and a half years old. Was working fine last time but when turned on now there is very little pressure through the hose and the water seems to be filling up inside...


this sounds like the seals may have been damaged inside the pump or that the water inlet/outlet could be damaged. If you take off the front cover (use a star bit screw driver) then run the pressure washer you will be able to see were it is leaking from and then you can get the right part to replace it.

I used my water blaster 2 days OK and all was fine. I have just used it again and water is spraying out around the trigger. Is this likely to be a break somewhere inside the handle or is the O-ring not...


This sounds like it could be a problem with the handle. The part number for the replacement handle is 2.641-202.0 when you call your local kacher supplier/dealer to replace it just ask them to make sure that the part number I gave you will fit onto your high presure hose as the fiitings can change from older and newer models.

Very low pesure


Make sure that all the air inside the hose is out, sometimes pressure washers have a hard time bleeding out the air. Lastly it could also be your pressure relief inside the valve body of the pump the spring can get bound up and basically stay on relief, like when you let off the trigger it doesnt just blow the line or stall the motor good luck\

KOHLER HYDRO 13 When pressure washer engine is


first sheck the inlet screen where the garden hose attaches,if there is water flow then see if it has a manual pressure regulator, this will be a knurreled knob somewhere on the intake manifold of the pump, ifyou have one, turn it clockwise and see if there is a difference. If still no luck, disconnect the high pressure hose from the pump, start it and see if warer flows at that point, Your gun may be clogged or your hose may be delaminating on the inside and need to be replaced. If all this fails I suggest you bring it to an expert. These pumps can require special tools and expertise to repair internally

I have had 3 Karcher pressure washers all experience the same problem and so have two of my neighbors. Our area has very hard water and it causes problems with the washer not bringing up the pressure when...


If your water is that hard (and it appears it is) WD40 will NOT solve the problem. You should look into a water softener. However, chances are that a small, inexpensive model will not have the flow capacity required for a pressure washer. You'll likely need to look at a larger, whole-house model.

Use vinegar to through the machine's "soap" dispenser to break up the hard water deposits or a heavier solvent such as CLR which is available at most retail outlets.

Karcher 3300 G water leak out rear of unit from white plasticplug


if its just a plug, remove it with an allen key and wrap a couple layers of teflon tape around it. That should stop, or at least slow down any leaks that are coming out of the threads.
