Strange smell from boiler...

Phil4432

I've been getting a smell from my boiler, not burning metal or plastic.  Smells more like food cooking; the closest description would be toffee, as weird as it sounds. 

Could there be dust inside the boiler burning off in operation?

Best to get it checked out by a gas safe engineer to be on the safe side

Yes, might be best.

I have a Fireangel Monoxide alarm, its still on 0.  Definitely can't smell gas.  But best not to use it for now.

Should I just not use it, or complete shutdown?

Probably safest to shut it down completely; turn the boiler to Off on the main controls and then turn off the isolator that isolates the boiler electrically. 

Is the boiler near a hob or stove? Do you have children? Might one the children put something into the boiler case?

No children.  Its in a bedroom.

Looking through the instructions, it just says to enter a code to shut it down.  https://www.johnsonandstarley.co.uk/sites/default/files/downloads/ZZ1431-5 QUANTEC HR-COMBI USERS INSTRUCTIONS FEB 2016.pdf

Its plugged into a normal mains switch also.

Thanks, good advice.  I'll shut down the boiler from the panel, turn off both the gas and electricity to it.
