This Vaillant repair job was for a customer in Rotherham which I did last week. The boiler was an old ecotec pro 28 which needed needed a service and needed the flexible rubber flow and return pipes replacing. The boiler had not been serviced in its 10 year life.

Vaillant ECOTEC Plus 831 Con fault
This was a repair I did on a Vaillant ecoTEC Plus 831 combi boiler recently for a customer of mine in Rotherham S66. It started off as an intermittent issue which only seemed to affect the central heating, where it would not come on at times.
