Hi
Got a Vaillant ecoTEC plus 832 Combi which has started to make weird 'clunking' noises when delivering hot water. Running the kitchen tap doesn't usually provoke it, but the bath tap will if the flow is anything more than a trickle. Heating doesn't seem to be affected although it hasn't been on much for a while.
Quick video with sound:
I'd just like a heads-up of what the problem might be and whether it is likely to be covered by the warranty. The boiler is about 6 years old with a full service history and, I believe, has a 10 year warranty.
Many thanks.
