Vaillant Boiler Repair. Intermittent F.53 fault code on a Vaillant Ecotec Plus boiler, leading to no heating or hot water.

Vaillant Boiler repair and service in Meols, Wirral

Basic electrical fault finding carried out to rule out any other faults, and to prove a faulty venturi/mass flow sensor was the cause. A new venturi was fitted along with a good strip down service, new graphite burner seal, and inhibitor concentration test - now a requirement for carrying out annual servicing!

Hot water and heating running nice and smoothly again and another happy customer!
