Common Baxi Boiler Fault Codes

  • E119 — Low water pressure. The boiler pressure has dropped below 0.3 bar. Repressurise using the filling loop. If pressure keeps dropping, there’s a leak in the system.
  • E168 — Electrical or PCB fault. An internal electrical issue has caused a lockout. Can sometimes clear on reset; if not, the PCB or wiring may need attention.
  • E133 — Gas supply fault. The boiler isn’t detecting a gas supply. Check your gas meter is on and other appliances are working. If they are, this points to a faulty gas valve.
  • E160 — Fan fault. The boiler can’t confirm the fan is running correctly. Usually means the fan or associated wiring needs replacing.
  • E110 — Overheat lockout. A safety shutdown triggered by high temperature. Can indicate a faulty thermostat, pump problem, or blocked heat exchanger.

If your boiler is showing a code not listed here, call us — we carry a full diagnostic toolkit for the Baxi range.

FAQs

  • What does E119 mean on a Baxi boiler?

    E119 means the boiler pressure has dropped too low. You’ll need to repressure the system using the filling loop – aim for around 1–1.5 bar. If pressure keeps dropping, there’s likely a small leak somewhere in the system that needs tracing.

  • My Baxi boiler is showing E168 - is it serious?

    E168 is an electrical/PCB fault. Try resetting the boiler first. If the fault returns, it usually means there’s a wiring issue or the PCB needs replacing. Don’t ignore it — call us and we’ll diagnose it properly.

  • How much does a Baxi boiler repair cost?

    Repairs start from £85. We’ll give you a quote before any work begins.

  • How quickly can you respond to an emergency?
