Viessmann Boilers Guide

Hi All,

I bought my Viessmann 200 boiler three years ago. I am extremely happy with my boiler’s performance but from the last two days, it is showing a Fault Eb. If I keep resetting the boiler, it starts up quite well & then runs all right for some time before showing the same error. I guess the main burner is not lighting. While trying to fix the issue, it makes fan noises & several ticking noises as if the boiler is trying hard to light a burner but giving up repeatedly. Someone, please help on this matter.

Thanks

John

Hello John, I guess there is a blockage in the pipework. Because when flow pipes are blocked, this leads to the flow temperature sensor react very slowly once the boiler fired up thus, as a result, you have an insufficient heat generated by your boiler. You should call an expert boiler engineer in order to power flushed the boiler & replace the pump which is rattling.
