Hub 3 red light

My Hub 3 has a red light for the last week, I have tried leaving it off several hours overnight, it re-starts with a red light.

Have also tried the factory reset several times, initially starts green then goes red before the inet comes back on.

The hub feels warm, I would not say hot but given the red light is a warning for overheating I would appreciate an engineer booked please to have this replaced, thanks.
