Viessmann Vidotens 200w vibration noise

[John.V]

Hi All,

I had a Viessmann Vidotens 200w combi boiler installed recently and there is a vibration noise coming from the boiler for about 2 seconds if i turn on a hot water tap when central heating is on. The same noise can be heard a few seconds after a turn the tap back off. The pressure gauge needle goes crazy at the same time. As the boiler is on a plasterboard wall, the vibration noise can be heard throughout the house. Any ideas what is causing the issue?

Regards

That's not good, agreed get back to the fitter.

Also make a recording of the fault while you can, hopefully not but Viessmann might have to get involved
