Citroen DS3 Help

Hi Dunno if this is the right place to post so sorry if that is the case.

Anyways - my citroen DS3 1.6 petrol uk model RHD today started a warning light on dash saying boot not closed (done all the usual cleaned up clasp and made sure no jams etc) at the same time back wiper stopped working and also no water to back wiper (there is water in it as front ones work) I am sure it is same washer pump that supplies back and front (as there is only one place to fill water up! and takes a few seconds to come through compared to front)

Anyways checked the wiper fuse and it's fine...dont see a fuse for washer pump (but I think that is working as already said front is fine) and dont see a fuse for boot locking...although rest of central locking now no longer works (but makes all the right noises) boot opens and closes just does not lock.

Seems strange for 3 things at rear to go at same time which would lead me to believe a fuse or relay...but why no water to rear jet?

Any Ideas...only thing I can think of is pinched water pipe to rear washer but then wouldnt wiper and boot still work...any help appreciated.

Cheers
