On the itinerary it should have been itemised and noted as not working etc. this covers the landlord and also records it as their property.
"Issue is I don’t want to mess with it"
I'd agree you shouldn't and that leaves you with 3 options
either speak to the housing association/LL about having it repaired - guessing it will be a no judging by your comment thus far
ask if you can arrange for it to be looked at, at your cost - as above keep a record of this
leave it and hope it won't go off
