Vaillant ecoTEC Plus 831 F.27 fault service and repair

Posted by adminon June 5, 2020November 22, 2021

I was recently asked to have look at an F.27 fault code on a Vaillant ecoTEC Plus 831 Combi boiler which wasn’t working, in Hillsborough, Sheffield S6. The customer said the boiler would try and fire up and immediately shut down.

This was a repair on a Vaillant ecoTEC Pro 28 Combi boiler that I did yesterday in Darton, Barnsley, S75.The issue was that the radiators would start getting hot when the hot tap was being run, which is not an uncommon fault with combi boilers in general.
