About this deal
Other issues can be fixed by a qualified engineer more easily, but the most effective way of avoiding an F62 is by replacing any old boilers with a modern, efficient boiler. Modern boilers have been meticulously designed and expertly crafted for not only peak performance, but also product longevity.
Even if your current boiler is an antiquated system or showing no signs of wear and tear it can still be a good idea to upgrade. iHeat FRN 843673 We are a credit broker and not a lender and offer credit from a panel of lenders.

The best course of action is to have an engineer come and run some electrical tests using a multimeter on your boiler. The benefit of using a Vaillant Specialist, is the certainty of the extensive range of genuine Vaillant parts that would be carried.
Deciding who to use for any boiler repair is often not straightforward at the best of times, in regard to cost, reputation, knowledge and convenience. If there is a fault with your boiler's PCB it can seriously hinder the performance of your boiler and it could be worthwhile getting a newer model. Depending on the complexity of the boiler, it should take 2-3 hours for a diagnostic and fitting. Other Common Boiler FaultsThis means that in the vast majority of cases a successful repair is achieved on any Vaillant boiler, given that they would normally carry around 95% of all the parts for the ecoTEC boiler range, also enabling them to change more than one part if necessary. There are certain symptoms that may point to a faulty PCB. Note that these cannot give you a diagnosis that’s 100% correct, so it’s always wise to hire a boiler engineer to inspect your appliance if you suspect a PCB error. Can a PCB be repaired? No, the boiler will just keep on being able to be reset, until ultimately the part in the boiler will fail. It is worth pointing out that in the same way the F.62 fault code starts to intermittently appear, a similar pattern also appears with other related Vaillant fault codes of F.27, F.61, F.63, F.64, F.65 & F.67.
