Common Baxi Issues We Find

Problems we regularly diagnose and fix during Baxi services.

E133 fault code

Ignition lockout — typically caused by gas supply issues, blocked condensate, or faulty ignition leads. A common cold-weather fault.

E119 low water pressure

System pressure has dropped below safe levels. Often fixable by topping up, but recurring drops suggest a leak needs investigating.

Pilot light issues

On older Baxi models, pilot light failure is common. Usually caused by a faulty thermocouple or gas valve issue.

Leaking from underneath

Water dripping from the boiler casing usually indicates a failing pump seal or heat exchanger crack. Best caught early at a service.
