You have a blockage in the nozzle. Try cleaning the jet out with a piece of wire and compressed air. You should be able to see through the nozzle when held up to the light.

SOURCE: Karcher pressure washer won't start

Dear ralph_birtwi,
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.
Regards,
fulltech.

This seems strange, as it is under warranty you can take it back or contact them about the situation. It depends were you purchased the machine but if it is a manufacturers fault they will fix/replace it.

Karcher 5/11c motor runs but no pressure


Firstly make sure the pressure set valve is turned the right way, fully anticlockwise I think.(if it has one I could be thinking of the next model up) and that the lance nozzle is in the correct position not set to detergent or mid point between positions. If that is ok it is probably the switch at the bottom of the machine. If under warranty send it back karcher switches are not good.

I have a Karcher K3.540 pressure washer. Won't take up detergent and motor pulses ever second if vari-lance increased towards maximim. Motor runs ok at lower pressure but can take 1min to start wh


This fault is within the control head, under the detergent valve is a small spring loaded valve that acts to induce the detergent, this will have failed, the shaft of the component breaks off the disk base leaving a small hole in the centre of the disk. This is enough to allow pressure past the component. The machine will pulse when operated and will not induce the detergent. I've looked everywhere to find this part as I have a karcher with the same fault.

Karcher K2.91 will not switch on unless you start on low pressure adjustable detergent lance had warranty claim for oil leak Can you tell me how mutch oil should be in pump ?


The oil in these pumps are factory filled and sealed, im not sure why there would be oil around the derergent lance... it sounds like your unloader valve/bypass valve is stuck and it takes a larger flow of water to activate it (as you get more flow on low pressure)

will have to be stripped down and lubed up or the bypass assembly/head replaced if its badly scored

I have tried to use my Karcher washer model 411A using the suction tube which is immersed into Patio cleaner bottle but it does not work what am I doing wrong


you have to lower the pressure at the lance for the detergent to be drawn into the hose. It works on a venturi principle.
on the lance you will have to twist or pull back the end for it to go into low pressure mode.

the easiest way to check it is working is to take out the lance extension , the bit that fits into the trigger on a bayonet fitting. run the machine and see if it then draws in detergent.

If it doesnt draw detergent then look to see if there is a detergent valve fitted to the filter that goes into the bottle and check that it is fully open. sometimes ther is a non return valve fitted into the filter too.
it could be that this non return valve has stuck. A poke with a bit of stiff wire should free it off its seat if it is that problem.

hope this helps a little

Dear mike husband,
One reasin for this fault could be a damaged lance or turbo lance. Try by replacing with new ones. If the problem is not solved, then the fault is due to a damaged spill valve. The spill valve could easily be damaged by using not suitable chemical or detergents. After using chemical detergents, one must always rinse the machine by passing pure water. The spill valve could also be damaged by leaving the machine for a long time with pressure in the system. One must never store such machines with pressure still inside. Always press the gun before storing.
Well the solution is to change the spill valve with a new one. In some cases even faulty suction valves can give this problem. But in the majority of cases it is the spill valve.
If you do not know how to fix this problem, it is better to be done by an expirienced technician.
Regards,
MG.
