Founded in Germany in the 1970s, Vaillant boilers have been a dominant feature in home heating systems and central heating for many decades. A popular and reliable choice for many homes, whether they have combi, regular or system boiler model, there are currently 11 boiler ranges in the Vaillant stable, including the popular eEcoFit, EcoTec and EcoTec Plus. This vital component pushes hot water around your central heating system and therefore if it does develop a problem, it is likely that your heating will stop working.

In some cases, where a major component needs replacing, you might want to consider buying a new boiler and we have recommended you get a quote from WarmZilla to do so.We certainly strive to provide the best possible customer experience.

Vaillant Boiler PCBs are present in all modern day appliances, large or complex systems can require primary and secondary pcbs to operate. The pcb is in charge of all operations, installed with routines to operate the boiler it was programmed for. Every action that occurs is monitored carefully by the PCB. Sensors and wires pass information and make it possible for the pcb to access live readings and adjust accordingly. Safety is the highest priority, so the boiler can be shut down by the pcb at a moments notice if a safety concern is detected.

The possible causes –low pressure is the cause of a poor flow rate, as there is not enough pressure in your boiler to push the hot water sufficiently around your heating and hot water system. This drop in water pressure can be caused by a faulty pump or be due to the height and position of the water tanks in your home. Issues with an open-vent heating system – which is seen on older boilers and has a feed and expansion tank – can also be to blame. While Vaillant have a reputation for quality and affordability, like all boilers they can also be prone to faults over time. And there are a few glitches that are common issues across the Vaillant range. The gas valve is not functioning correctly, and as a result, the boiler is not getting the right amount of gas to produce the correct flame.

Unless you are a qualified gas engineer yourself, this is not a problem to take on on a DIY basis. You will need a Gas Safe Engineer to sort this one out. Your system’s flow rate is simply the rate at which water comes out of your taps or the showerhead. If this rate is slow, then it is considered a poor flow rate and will be seen when you first turn the taps or shower on – the water will take time to come out and will then not increase in flow or pressure.

The PCB is your boiler’s motherboard – the essential component that links everything else together and keeps the boiler working. This will usually manifest itself in a Valliant boiler as an F27 code on your display panel. There are a number of possible causes for this error code: If you are quoted a big price to fix what is already an old boiler, it is generally worth giving some serious thought to investing in a whole new boiler. Some of these could involve a simple fix or a bit of maintenance, but others can be more serious problems.
