Vaillant Boiler Repairs Swansea & South Wales
Vaillant is a German heating technology company founded in 1874, and one of the most respected boiler manufacturers in Europe. Their ecoTEC range is one of the best-selling boiler lines in the UK, known for high build quality, efficiency and reliability. Vaillant boilers are fitted in many properties across Swansea, Neath, Port Talbot and the wider South Wales area. Our engineers are experienced in all aspects of Vaillant boiler repair, servicing and installation.
Vaillant Boiler Repair
When your Vaillant boiler breaks down, you need an engineer who knows the brand inside out. Our Gas Safe Registered engineers have repaired hundreds of Vaillant boilers across Swansea and South Wales. We carry common replacement parts on our van, which means many Vaillant repairs can be completed on the first visit — getting your heating and hot water back up and running as quickly as possible.
Common Vaillant Boiler Problems
Through years of working on Vaillant boilers, we have become familiar with the faults these models are most prone to. Here are the issues we see most often:
- F28 error code — ignition failure, one of the most common Vaillant faults. Caused by gas valve, electrode or wiring issues
- F75 error code — water pressure sensor fault, the sensor may need cleaning or replacement
- F22 low water pressure — requires repressurisation and investigation of the cause
- Dripping from the PRV — pressure relief valve discharging due to expansion vessel failure
- Noisy pump — the Grundfos pump fitted in older ecoTEC models can develop bearing noise
- Intermittent hot water — diverter valve cartridge sticking, a very common combi boiler fault
If your Vaillant boiler is displaying a fault code or behaving unusually, do not ignore it. Early diagnosis can prevent a minor issue from becoming an expensive repair.
Vaillant Boiler Servicing
An annual boiler service is essential for keeping your Vaillant boiler running safely and efficiently. During a service, we carry out a comprehensive set of checks including flue gas analysis, gas pressure testing, electrical connection inspection and a full visual examination of all components. Regular servicing not only extends the life of your Vaillant boiler but is also a requirement for maintaining most manufacturer warranties.
