When the electric shower is turned on, the lights in the bedroom and on-suite become 'Dim' this lasts until the shower is turned off ...... any ideas why?
I've had a think and I've come up with two possiblities:
- The lights for the bedroom and on-suite have been created from a 'spur' from the shower circuit and when the shower is turned on, it is taking the power from the lights.
- Faulty consumer unit (fuse box).
Any comments or other suggestions?
