Question and Answers


Why is my power washer leaking a grease/water mixture?


The pump should have 140 ml of 80-90 motor oil in it and not water. You should be able to disassemble the pump and replace the o-rings that come in the o-ring repair kit.

It sounds like you caught the problem early enough to prevent serious damage.

I can't locate a pump manual to assist you in the repair. The parts diagram should give you some guidance in the repair.
