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 The key is to understand what is causing the problem and that is what this guide is all about. While we can’t explain every possible fault, we can go into more detail about the most common faults.

Your ignition is essential, and it keeps the flame burning, which in turn heats up water as it passes through the pipe. A faulty or failed ignition is a relatively common issue with Vaillant boilers and will be displayed as an F28 fault code which you need to look into. The first instinct most people have when there is a problem with their boiler is to call out an engineer. Sometimes this is needed, but there are times when you can fix the issue quite simply yourself. This would usually indicate an issue with the fan. If you speak to Vaillant technical support they would suggest to disconnect the fan and see if the appliance goes to the F.32 fault code. If this isn’t the issue, you will need to get a gas engineer out and should not mess around with anything. Dilute these too much and you can end up causing more serious problems to the boiler that you already have. #2 Pump problems

The PCB is your boiler’s motherboard – the essential component that links everything else together and keeps the boiler working. As central heating and hot water issues are the last thing you want in your home, especially during the colder months, it makes sense to also know the likely causes if you have a Vaillant boiler system in your home. And a little prior knowledge can not only save you time, as well as help you to avoid cold showers, it can also save you on expensive repair or energy bills. 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.

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 fault code is known to show up with fault code F27. The difference between F27 and F28 is that F27 is failure immediately after ignition, whereas F28 is complete failure to ignite. Part Numbers If you are getting an F75 error code, it is almost certain you have an older model of Vaillant boiler. These older models were fitted with a Wilo pump, as we mentioned above, and these are known for being unreliable and easy to break.This fault code is most common on the Valliant Ecotec Plus and Ecotec Pro models, and especially the Vaillant Ecotec Pro 28. Just like other boiler makes, Vaillant boilers will display a fault code – a number beginning with F – on their display so you can more easily identify what may be going wrong with your system. Different issues will have a different error code so if you see an F number displayed, refer to your boiler’s manual for the full list of fault codes for that model. How Long Should a Vaillant Boiler Last? Use trace heating if required and installed according to the trace heating manufacturers recommended instructions.

Possible causes– a malfunctioning thermostat or dirty air filters are the two most common causes of an overactive boiler. If a faulty thermostat indicates low temperature, it an keep the boiler running unnecessarily as it thinks the water is not being heated.

Other possible pump issues include split or deteriorating seals and possible limescale build-up too (particularly in hard water areas). 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. If run externally make sure it is of large diameter pipe size ie 32mm and 40mm (insulated if possible or required) Some of these could involve a simple fix or a bit of maintenance, but others can be more serious problems.
