What's Included in a Vaillant Service
Common Vaillant Issues We Find
Problems we regularly diagnose and fix during Vaillant services.
F75 fault code
Water pressure sensor or pump fault — one of the most common Vaillant faults. Usually needs a sensor replacement or pump check.
F28/F29 fault codes
Ignition failure. Can be caused by a faulty gas valve, blocked condensate pipe (in cold weather), or electrode issues.
Fluctuating pressure
The system loses pressure over days or weeks. Often caused by a failing expansion vessel or micro-leaks on radiator valves.
Noisy pump
A buzzing or humming pump is common on older ecoTEC models. Usually indicates the pump bearings are wearing and need attention.
