It will only pick up detergent if you use a low pressure detergent nozzle - or no nozzle at all. It also takes a while for the detergent to get to the nozzle.
SOURCE: karcher pressure washer leaking oil
all 4 stroke engines have oil, and 2 stroke can have a oil mixer reservoir to mix with engine gas or to lube the chains , gears, pumps.
If yours is 4 stroke as likely then the oil may be leaking at the seals to the main. (bad news)
Pressure wash it (lol) and locate the leak,
to speed up the leak you can pump some compressed air into the engine (be creative)

detergent can only be **** from the container only on low pressure.
SOURCE: trouble with Karcher Pressure washer
Dear Pgarciax,
It is important that you must have mentioned the model number of your Karcher. Just the same I can surely say that your machine's fault lies in the "SPILL VALVE"
When the gun is open and pressure is being produced, the spill valve is in a relaxed position. Also it has at the bottom a valve, which when pressure is produced it is closed. If this does not close due to dirt or corrosion, the pessure goes down. Now when you close the gun,pressure forces the spill valve down to close the electrical system. Now if the "o" rings of the spill valve are damaged, the machine will start going on and off while in stand-by. So if you know how to locate the Spill Valve, all one has to do is change it with a new one.
In some Karcher machines there are 2 spill valves. One regulates pressure and the other one is for switching off the machine when the gun is closed.
Low pressure could also be due to faulty suction or delivery valves. Most probably the suction valves.
But when saying that there are short interruptions while in stand by, I stick to the fact that the spill valve needs renewing.
Regards,
MG.

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.
