Had the same problem with my 2001 330ci. If not used frequently the pump will get waterlogged and allow fluid to seep into the motor. I was able to disassemble, clean, and rebuild my pump but I would recommend replacing it, it is not expensive at around $20-30 and easy to change.
The washer pump is inserted into a hole on the washer tank itself. It is an interference fit so it will pop out. If you have significant amount of fluid in the tank it will leak out of the hole. There should be one hose connected with a clamp and one electrical connector. I believe there may be a plastic shroud covering it which needs to be unsnapped.

not likely that fuse blew but check fuse box for wiper fuse and see if blown, when u fill fluid, turn ignition on but not running hit squirter and listen for pump noise if noise is present then hit repeatedly and look if there is any leakage dripping and trace leak, if no noise check resivor for debrie floating (posisible blockage) last thing is check for power at pump with wire probs

On the drivers side of the vehicle just behind the front bumper is the washer fluid reservoir. The washer pumps (2 - one for the back and one for the front) are located ont the face of the reservoir.
1) Drain the resevoir. (You can reuse this fluid, so put it in a clean container)
2) Disconnect the wiring harness for the problem pump.
3) Remove the sprayer line.
4) Remove the pump. It is held in by being snapped into a channel on the resevoir and by the rubber grommet. This may take some elbow grease.
5) Remove the old grommet.(If your new pump came with a new grommet)
Installation is reverse. Usually new pumps come with new grommets. If not, it is ok to reuse the old one.
