Quick fault lookup

Most common Baxi fault codes

These are the codes Wokingham homeowners report most often. See the full fault code guide for the complete index.

E119

Low water pressure

Pressure below minimum. Repressurise to 1.5 bar using the filling loop or key. If pressure keeps dropping, hidden leak — engineer required.

E133

No gas / ignition failure

No flame detected within expected time. Check gas supply and meter credit first. If it returns, ignition electrode or gas valve needs inspection.

E168

Fan fault

Fan not running correctly — prevents safe flue venting. Do not reset repeatedly. Gas Safe engineer required immediately.

E125

Circulation fault

Boiler has detected a problem with water flow, often linked to a failing pump or trapped air. Engineer inspection required.

E130

Flame loss during operation

Flame detected then lost while running. Often a gas valve, sensor or combustion issue. Engineer diagnosis required.

E50

Internal fault

General internal lockout. Try a single reset. If it returns immediately, a Gas Safe engineer is needed to diagnose the cause.

Common questions

Baxi boiler FAQ

How much does a Baxi boiler service cost in Wokingham?

Thermotec charges from £96 fixed price for a Baxi annual service in Wokingham, including a full safety check, combustion analysis and digital Benchmark record. Landlord CP12 combined with a service is £150.

What does the E119 fault code mean on a Baxi boiler?

E119 means low water pressure. Repressurise to 1.5 bar using the filling loop or filling key. If pressure keeps dropping more than twice a year, there is likely a hidden leak and a Gas Safe engineer is needed.

What does the E133 fault code mean on a Baxi boiler?

E133 indicates the boiler did not detect a gas supply or flame within the expected time. Check the gas supply and meter credit first. If the fault returns after a reset, the ignition electrode or gas valve likely needs inspection by a Gas Safe engineer.

Can you repair older Baxi boiler models?

Yes — Thermotec services and repairs both current Baxi 800 and Platinum models and older ranges including Duo-tec, EcoBlue, MainEco and Solo HE. Parts availability is checked before any repair is quoted on older units.

Do you have Baxi manuals for download?

Yes — Thermotec provides downloadable PDF manuals for all major Baxi models including the 600, 800, Platinum, Duo-tec, Megaflo HE, EcoBlue Advance, MainEco and Solo HE ranges. See the manuals section above.
