We sell original heating parts. Our engineers fully refurbish parts to the highest standard and test them. So, buy with confidence. Fits Appliance(s) A boiler circuit board also monitors pressure, temperature, and currents, to ensure that the boiler is: However, don’t confuse this with flashing — some boilers use flashing as a signal they are in service, or have a fault. #2 – Burning Smell Coming From Boiler As frustrating as it may seem, the F62 represents a serious fault with your boiler and it must be analysed and fixed by an expert, a Gas Safe registered engineer. Should I get a New boiler?

Boilers from original EcoTec range with PCB part number: 0020132764 can be found on attached list below this post. Of course, there is an option to spot-weld to repair the PCB. But, given the time it will take, it’s much wiser to replace the whole unit. Fault finding isn’t always easily — there’s a tonne of the things that can cause your boiler circuit board to fail. This price drops if you’re considering a refurbished or reconditioned unit, but again, it’s rarely worth the small cash saving to have a second-hand unit (that has no warranty). Should You Replace Your Boiler? In some circumstances, it can even be that both parts are faulty and have to be replaced (but thankfully this is very rare).

What does PCB stand for?

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. FRN 843673 We are a credit broker and not a lender and offer credit from a panel of lenders. We may

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. So, with the above having been explained, what approaches are there when exploring the subject of getting the Vaillant F.62 fault resolved?

In an ideal world, it would be great to get the Vaillant F.62 fault fixed professionally, in a single visit, without wasting time and money. However, in our experience as Vaillant’s agent, we find it’s usually the PCB (9 times out of 10) that needs changing. The F62 error code on Vaillant boilers indicates a problem with the gas valve. Specifically, it means that the gas valve has failed to open during the ignition sequence. Now, let’s have a look at some common symptoms pointing to a PCB problem. #1 – Intermittent Display Panel Operation 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.

Depending on the complexity of the boiler, it should take 2-3 hours for a diagnostic and fitting. Other Common Boiler FaultsMost Vaillant ecoTEC plus and pro boilers can experience a problem with F.62 failure. As Vaillant specialists who carry out ecoTEC boiler repairs and services on a daily basis, we find that the majority of F.62 fault error codes occur on the earlier Vaillant ecoTEC pro and plus R1 boilers. These first ecoTECs were produced from 2005 to 2012. This F.62 issue on these older R1 models (normally at least 10 years old), is much more prevalent than on the later updated ecoTECs (or “ecoTEC 2”), which have been produced since 2012. product chosen and the amount of credit taken out. Not all products offered by the panel of lenders When 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.

This can happen due to a variety of reasons, such as a fault with the gas valve itself, a problem with the wiring or connections to the gas valve, or a fault with other components in the ignition circuit. Causes However, if the valve remains open when the boiler is not in use, it poses a significant risk of a gas leak, which can be very dangerous.When a F.62 fault code is triggered, as well as stopping the boiler from operating any further, the error code message also informs that a specific fault or problem has occurred in the boiler. 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 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? There is written information from Vaillant covering the F.62 fault code, but NOT how to fix it, for obvious reasons! For example, the air pressure switch may send a signal to the PCB that the fan is operational (helping to vent gases out the flue), and therefore it’s safe to ignite the boiler.
