Hi
Vaillant turbomax 828. Ignore the rattles and fan noise - its been like that since we moved in 6+ years ago
Recently changed the HW heat exchanger, and all good. Boiler working well for hot water and heating.
However, it is making a strange noise which is sounding like a jet fly past, or elephant, or trumpet. Only briefly, and only at the start of cycle. It happens on CH so its not the changed parts. The wife says it was doing it for a while before hand, just not as bad.
Researching suggests its either (a) debris or flow constriction in the primary (flame-water) heat exchanger; or (b) CO2 mixture on the gas valve needing adjusting; or (c) its debris in the pump. (The pump was removed during the HE swap). Nothing visible appears to be resonating.
Seems strange its just come on but its possible some new (or moved) debris is now at the primary HE/pump as the boiler was pressurised/emptied a couple of times. And its possible the gas valve may've been accidentally touched/knocked during HE replacement.
I've attached a short sound clip - and the noise is from 10-21s and would never be heard from again. (attachment is a ZIP file containing a short audio file).
Is anyone able to point at what element this might be?
If its debris, then I'll give it a flush and clean.
If its gas valve needing adjustment, then I'll get someone in, but what "skill" am I specifically looking for? Any gas-safe engineer? Or one with tool XXXX? Vaillant specific?
Many thanks
