I'm in the middle of a bathroom refurb and the plasterer spilt a small amount of liquid which has leaked through the ceiling below in the vicinity of the pendant light. The light has stopped working. I'm guessing its fused, but none of the switches in the fuse box have tripped, and the other lights on the circuit are working ok. Do I just need to wait for it to dry out or will I need to get someone to change a fuse in the switch, or something else?
