You first need to answer the question - what washer additive have you been using?

This is because if you've been using BMW Concentrate, then it narrows-down the number of possible causes. The odds are it's just a faulty motor that needs replacing.

But if you've been using 3rd-party concentrate, then there are more possibilities for why it's not working and you probably have more work on your hands to correct the issue than just replacing the motor.

Yes, in any case, it's worth replacing the fuse and if the motor works again, you'll be able to flush the system out by disconnecting the hose at the nozzle and running clean water through until it's clear. Once you have clear water at the nozzles, then you would use BMW additive exclusively from now on. This would obviate well-known problems of the washer system 'gunking up' when some 3rd-party additives are used.

But if replacing the fuse has no effect, then you probably have a lot of work on your hands to get to the washer reservoir and pump and see what's happened. Worst case scenario you have to replace the reservoir and the pump and then have to flush the pipes.

In any event, it helps us to know if you've been using BMW additive exclusively, or been using 3rd. party additive (or a mix of BMW and 3rd Party).
