SOURCE: Can't fine where to put pump oil in
Dear glenoaks06,
I handled various Karcher washers, but the 2500 I never came across it. Just the same I will give you a few hints and maybe the solution for the problem. When the oil is milkey this means it has water in it. This means that there are faulty seals for sure. Now in many Power Washers the compartment where the oil is located is filled with oil prior to assembling the head unit that contains the pistons. So you have to take apart the the complete head change all seals( HP seals, LP seals and OIL seals). There are pumps that take multi-grade oil(15/50) and others 90 grade oil. If your pump is fan cooled, it probably takes 15/50 oil. Now one of the main biggest problem of water in oil is Faulty and Scratched PISTONS.
So when you have the pump apart....check condition of pistons. It is useless to change seals if pistons are damaged.
Now one thing regarding your problem, is that you have to put together the head with the pump upside down, so that you can fill the compartment (where the pistons are pushed by the swash plate), with OIL, before you put back the complete head with good pistons,springs,seals, valves...etc..etc. These few hints are relevant to quite a number of Karcher washers.
Regards,
Fulltech.

SOURCE: How to put oil back into the Karcher water pump
You need to remove the pump and sit it brass side up before removing the bolts holding the brass to the aluminum part (you have to do it that way so the oil doesn't spill out.) CAUTION: there is some spring tension on the brass head.
Take the brass head off and set to the side on a rag or in a bucket. Dump out whatever oil is in the oil side, making sure not to drop the swash plate or bearing (the pieces sitting in the oil). Fill the oil end with aproximatly 4.5 ounces of Karcher pump oil, (or just 20w 50 weight non-detergent oil). Put the brass head back on and tighten bolts. Put the pump back on the machine.
If this helps please rate.

Usually electric pressure washers only have oil on the pump, so its very likely that you will find the problem there. I'd say check all the pump seals and if that doesnt solve the problem, you can check to see if all bolts are tight when you close the pump back.
If by any chance you are looking for a new machine and/or parts for your machine, log in to www.roncoshop.com where you will be able to find pretty much anything for your preassure washer.
