Additionally, even if a manufacturing error is the root cause of the F27 fault, you should verify that your boiler warranty is still active. The standard warranty for a Vaillant ecoTEC Plus boiler is five years, but it can be extended to seven years if installed by a qualified professional. For the ecoTEC Plus range, the standard warranty is two years, but it can also reach seven years with the proper installation. Fingers crossed, this is a fan speed issue, not a faulty boiler fan. If this is the case, a Gas Safe engineer will be able to adjust the fan speed and reset the boiler. #2 – Loose Wiring/Connections

With all that settled, it is time to look at a few of the most widespread signs of a faulty boiler PCB. Boiler shutting off before getting to the required temperature As this is a gas-related problem, make sure that you ponly use a fully qualified engineer to fix your heating system. F61 fault codes on Vaillant ecoTEC boilersFurthermore, improper handling or installation of the PCB can also cause faults. If the PCB is not handled or installed correctly, it can damage the components or result in incorrect connections, resulting in malfunctions. Cost of replacing a PCB Through the boiler’s flow and return pipes, the thermistors monitor the boiler temperature. The boiler’s flow and return temperatures will differ from each other when it is operating properly. This is because heat is absorbed by the heating system. This will fluctuate through the boiler’s operation. If it isn’t working properly, you will see one the Vaillant fault codes. Your boiler’s control center is the printed circuit board. It is the control hub for every electronic component so wiring problems can be a big issue. The boiler will not be functioning properly and shut down if the PCB is damaged. It can be expensive to replace the PCB so a new boiler would be recommended in this case. Any noise stems from vibration. And this vibration (over years) can cause the connections and wiring to come loose.

Vaillant boilers have an F61 error code which means either the boiler or gas valve components are not communicating correctly. This could be due to many factors. Once you’ve thawed out the pipe, you must insulate it using lagging. If you’re in a particularly cold part of the UK, ArmourFlex lagging will provide a bit more protection than traditional lagging. #3 – Air Pressure Switch These vibrations can help to loosen connections over time. If the connections become weak, the signals these vibrations send to the PCB may be intermittent. This PCB is suitable for Vaillant Ecotec boiler models. All our PCBs are tested and refurbished by our qualified, trained and experienced technicians. Moreover, all our products come with 12 months warranty In conclusion, the price of Vaillant PCBs can vary depending on several factors, including the model, age, and condition of the unit. It is important to note that purchasing a new PCB can be costly, but it may be necessary to ensure the proper functioning of your boiler or heating system.

Combi boilers are best suited for smaller homes, where heating and hot water demands aren't extremely high. Hot water is only generated when it is required and doesn't require a water storage tank. Combi boilers are compact in size, meaning you are free to fit the boiler almost anywhere that is safe in the house and can also be cupboard fit. In conclusion, the cost of repairing or replacing a boiler PCB board can vary depending on several factors. If you are confident in your abilities, you may be able to save money by opting for DIY repair or replacement. However, if you are not confident or do not have experience, it may be best to hire a professional. Signs That Your Boiler PCB Board Needs Repair or Replacement Your boiler’s printed circuit board (PCB) is an essential component that controls the functions of your heating system. It is responsible for the safe and efficient operation of your boiler. If your PCB is faulty, it can cause your boiler to malfunction, leading to reduced efficiency, increased energy bills, and even a complete breakdown. When a boiler shuts off before reaching the desired temperature, it indicates a communication breakdown between the PCB and the thermistor. The thermistor is responsible for transmitting accurate signals to the PCB, determining whether the water has reached the ideal temperature. If the signals are incorrect, the PCB may mistakenly assume that the water has reached the desired temperature and shut off the boiler prematurely.
