Random rumbling noise on new Vaillant Ecotec Plus 615 VU

[Paul Fourmy]

Hi all. I've recently been getting regular complaints from customers about their new ecotec plus 615 vus regarding an intermittent loud rumbling noise. Checked high and low co2 ratios, gas inlet pressure etc but never find a cause? I've had Vaillant go back to a few but they dont give me any feedback. Has anyone else had this?

I have noticed this!
Have no clue what it could be would love to know what
Every single one when the fan stops running it sounds like a helicopter whirring down

Gentlemen if we are gas safe could we please get your gas safe details. We can then get you access to the gas safe forum. I realise nothing has really been discussed here as yet but remember, no gas discussion in open forum. Ta muchly
