18 month old Vokera Compact 29 combi boiler installed with new radiators, pipes, the lot (renovation project).
Recently inside the last 2 months the boiler has started to 'whine' when running the hot water (YouTube: https://www.youtube.com/watch?v=qaN4Rrvy2BM).
Rarely does the whine occur with just the central heating although it does on some occasions but only for a short while and only very quietly.
I've taken the cover off and the pump is turning fine with no play, the fan is working again with no play.
If I cover and restrict the silencer the whine continues which in my mind rules out the fan as I would expect it the noise to stop as the fan is turning / pulling less and less.
Sound seems to be coming from within the exchange heater, if I place a screwdriver on the case and put my ear to the driver I can convince myself its strong in one particular corner than the others - although it's loud it seems to be coming from everywhere.
Answers on a postcard please.
