Common Baxi faults

Baxi fault codes we diagnose

E168 — gas valve or PCB fault
E133 — ignition lockout, check gas supply first
E119 — low water pressure
E28 — NTC thermistor fault
Baxi boiler clicking but not igniting — faulty spark electrode
Radiators cold at top — air in system, bleeding required
Boiler making loud banging — delayed ignition or scale build-up

London's hard water accelerates limescale build-up in boiler heat exchangers — a common cause of reduced efficiency, kettling noise and boiler failure across all brands. Annual descaling as part of a boiler service extends appliance life significantly.
