Baxi duotec noisy DHW.

[Baloo790]

I was reading the earlier post about a noisy pump on a 28 duotec. Thought I'd ask as it was mentioned in that post, I love these bad boys, fitted loads but have had a rattleling in what sounds like the flow switch when hot tap open in one. I've ignored it as it's in a loft and can't be heard from down stairs, any ideas for future reference?

Probably the hall sensor/flow turbine rattling

Replaced a DCW inlet valve because of "whistle" yesterday .

The Vaillant's flow senors could make rattle/clicking sound..........

What's a DCW ermitrude? Short for something but can't think what?
