I removed the front windshield washer pump, knocked and blew on the openings, reconnected it, and it worked again. Might have been as simple as an electrical connection fault. Worth trying before you spend $40.00 for a new pump. Just unplug the bottom hose, lift the motor yup from the bottom with a flat-head screwdriver and pry it out from the slot, then unplug the top electrical connection. Easy fix.
I have an 09 W164. the pump is good. It runs fine on 12V drawing 1.6A. It is not getting 12V. I cannot find which relay/fuse powers it. There is NO mention of it on my fuse/relay diagrams. Any toughts, please?
It appears you have the smaller reservoir MB no longer sells this one; only the larger one is available now, which requires more disassembly, unfortunately. But good video just the same I think pumps are the same

Excellent instructions, thank you!
Very useful thanks!
Where is this other video that you mention, that shows how to remove the lower screw and tube from the old pump, and how to reinstall on new one?
