Why should I maintain my Vaillant boiler?

Regularly Vaillant boiler maintenance is essential to ensuring that it continues to perform optimally. All boilers must receive regular servicing in order to meet their full potential. Faulty boilers not only become inefficient but are also extremely dangerous raising the risk of carbon monoxide poisoning.

Fault codes in Vaillant boilers

Vaillant boilers display fault codes whenever the system is malfunctioning. Fault codes should always take priority over any other display functions. In the event of multiple faults occurring simultaneously, the corresponding fault codes are displayed on an alternating basis. If you are experiencing a fault as indicated by a fault code on your boiler display, you should hire a professional to address the problem immediately. The Vaillant ecoTEC boilers frequently display an F.75 fault code. This has to do with an issue pertaining to the pressure sensor. It can be difficult to diagnose and cure because the root cause is not always clear. However, Vaillant offers a retrofit modification that can be installed to permanently address this issue. The engineers at NXG Heating are highly familiar with all of the various fault codes and can immediately identify and rectify any problems that are occurring.

Pressure problems in Vaillant boilers

Vaillant boilers should never be under or over pressurised. In the event that this should occur, modern boilers are designed to cut out immediately to prevent any dangerous accidents. Unfortunately, this will create inconvenience as you will lose access to your heat and hot water. It is important for property owners to always monitor the pressure gauge to ensure that it does not go above or below the normal range. If the system has not been maintained on a regular basis, the pressure may need to be recalibrated. Irregular maintenance or failing to properly close a bleed screw may result in an undetected small leak causing pressure fluctuations. Another common problem is when people overfill the system in to the red zone using the filling loop. If you have overfilled your system or you can observe pressure problems, you should consult a NXG Heating professional immediately to rectify the problem.
