This is a repair I did on a first generation Vaillant ecoTEC Pro 28 in August 2018 in Aston, Sheffield, S26.
The fault was an intermittent F61 fault code with the boiler needing to be reset each time. In this instance the printed circuit board was failing and needed to be replaced.
I carry brand new printed circuit board’s and a reconditioned option for service and repair on Vaillant ecoTEC boilers. I can fix this F.61 problem with one visit, at a rather reasonable rate if I do say so myself.
Hi. Need a vailliant boiler looking at urgently. Same fault. S71 2PX. Can you help ?
