Before we conclude, we’d like to answer a few questions that we often hear about PCB fault finding on boilers. How long does it take to replace a boiler’s PCB? Note that these symptoms can easily be misdiagnosed, as most aren’t limited to one faulty part. For example, a display panel failure could be a boiler circuit board issue, OR an electrical supply issue. Likewise, a malfunctioning fan could point to a boiler PCB problem, but it could just as easily be the fan itself. Fault Finding With a Boiler PCB Since the boiler’s PCB effectively controls all internal electrical components, when it fails, they can malfunction. So, with the above having been explained, what approaches are there when exploring the subject of getting the Vaillant F.62 fault resolved? In some circumstances, it can even be that both parts are faulty and have to be replaced (but thankfully this is very rare).

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. PCB stands for “Printed Circuit Board”. It’s a laminated board with electrical conductors, which is essentially a control centre that facilitates communication between various electronic components of a device. PCBs are used in a vast array of electronic devices, including boilers. What is a PCB on a boiler? There is also the benefit that a specialist would probably use a “one-off labour price” type charge.a faulty PCB that sends incorrect signals to the valve can cause it to open and close at the wrong time, leading to gas flowing through when not required and no gas when you need it. Intermittent connection When the Vaillant ecoTEC plus and pro boilers get around (or beyond) 10 years old, defects in certain components can occasionally develop. It is these developing faults (in either the PCB or the Gas Valve) that are responsible for the boiler starting to fail intermittently, with the F.62 fault error code. An error code is exactly as it sounds, an alphanumeric code (F62) displayed upon a boiler's control screen or window, usually found at the toe or in the centre of the boiler. So, it could be that the PCB (as it is most times) is causing the F.62 fault, but it can also be the Gas Valve that is the defective component causing the failure! 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.

No, the boiler will just keep on being able to be reset, until ultimately the part in the boiler will fail. Usually, there are two different approaches that customers take, when trying to get a F.62 fault error code repaired on their Vaillant ecoTEC plus/pro combi or system boilers. These are to use any Gas Safe Registered business that is qualified to work on boilers, or use a dedicated Vaillant repair specialist who serves your area. Likewise, NTC thermistors communicate via the PCB to tell the boiler whether the difference in temperature between the flow and return pipes is within working range.

How Long Does a PCB Take To Fit?

In theory, yes, it’s possible to repair a PCB that hasn’t completely failed. The Gas Safe engineer inspecting your boiler will be able to determine whether repairs are appropriate. Some customers we visit can still painfully recount, costly and frustrating previous experiences they’ve had, after choosing the wrong company for their boiler repair! When a fault error code of F.62 flashes, or is shown on the digital display screen of a Vaillant ecoTEC plus or pro combi or system boiler, it usually means that a fault has developed in either one of two integral boiler parts; the PCB (printed circuit board) or the Gas Valve. We are proud of the quality of our refurbished parts and they come with 12 months replacement warranty. Your receipt will be the proof of warranty and please keep them somewhere safe. In this blog we’ll be taking a look at the F62 error code displayed by Vaillant boilers, including - what it means, what causes it and how it can be fixed. What is a Boiler Error Code?

The VAILLANT 0020132764 PRINTED CIRCUIT BOARD is a genuine, brand new Vaillant Boiler Spares product, covered by a Vaillant Boiler Spares manufacturer's guarantee. Only a Gas Safe Registered engineer/installer, who holds the appropriate qualification, is legally allowed to work on a Gas boiler. 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. iHeatWhen you replace Vaillant PCB you will have to adjust DSN (Device Specific Number) parameter for the boiler. Reason for that adjustment is the fact that entire original range of EcoTec boilers share one PCB. By adjusting DSN you pair your new PCB with your boiler. The same PCB will do all combination and system boilers from original Eco Tec range.
