The problems we catch on Vaillant services.
Water pressure sensor or pump fault — one of the most common Vaillant faults. Usually needs a sensor replacement or pump check.
Ignition failure. Can be caused by a faulty gas valve, blocked condensate pipe (in cold weather), or electrode issues.
The system loses pressure over days or weeks. Often caused by a failing expansion vessel or micro-leaks on radiator valves.
A buzzing or humming pump is common on older ecoTEC models. Usually indicates the pump bearings are wearing and need attention.
