🛠️ Common Vaillant Faults We Fix in Marylebone
If your Vaillant boiler is showing an error code or struggling to perform, here are some issues we’re called out to regularly:
F22 – Low Water Pressure
We’ll repressurise the system, check for slow leaks, and test the expansion vessel to prevent repeat faults.
F28 / F29 – Ignition Issues
We diagnose and fix problems with ignition electrodes, gas valves, and flue blockages to restore safe operation.
F75 – Pump or Sensor Fault
Common after radiator bleeding. We’ll inspect and replace the pump or sensor, and flush the system if necessary.
F62 – Gas Valve or PCB Problems
We identify faulty components quickly and replace them using genuine Vaillant parts.
F76 – Overheating
We’ll check circulation, pump flow, and descale if needed to prevent long-term damage to your system.
F83 – Flow/Return Imbalance
Our engineers will rebalance your system and check pump performance to resolve temperature differences.
💡 Not sure what your fault code means? Just ask — we’re happy to help explain and advise before we even arrive.
🔄 When It’s Time to Consider a New Boiler
In some Marylebone properties, particularly older or heavily used systems, it may be more cost-effective to replace rather than repair.
We’ll always be honest with you. If your Vaillant boiler is:
- Over 10–15 years old
- Experiencing repeat breakdowns
- Showing corrosion or scale internally
- Producing multiple error codes or expensive part failures
We’ll talk you through your options and, if appropriate, recommend a modern, energy-efficient Vaillant boiler that fits your lifestyle and space.
