Common Worcester Bosch Boiler Fault Codes

  • EA 338 — Fan or flue pressure fault. The boiler can’t confirm adequate air flow. Often caused by a blocked flue, faulty fan, or air pressure switch.
  • E9 — Overheat lockout. A safety shutdown triggered when the boiler gets too hot. Can indicate a faulty thermostat, pump issue, or blocked heat exchanger.
  • A2x — NTC temperature sensor fault. The sensor monitoring flow temperature has failed or is reading incorrectly.
  • D5 / D6 — Condensate pipe blockage. Common in cold weather when the external condensate pipe freezes.
  • C6 — Fan speed fault. The fan isn’t running at the correct speed.

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

FAQs

  • How much does a Worcester Bosch boiler repair cost?

    Repairs start from £85. The final cost depends on the fault and any parts required. We’ll give you a clear quote before any work begins – no surprises.

  • My Worcester Bosch boiler keeps losing pressure - what's causing it?

    Pressure loss is usually caused by a small leak in the system, a faulty pressure relief valve, or a problem with the expansion vessel. It’s one of the most common Worcester Bosch faults we see. We can diagnose and fix it on the same visit in most cases.

  • Is it worth repairing an older Worcester Bosch boiler?

    Worcester Bosch boilers are built to last – many run well beyond 10 years with regular servicing. If the boiler is under 10 years old, repair is almost always the better option. We’ll give you an honest assessment before recommending anything.

  • How quickly can you respond to an emergency?

    We offer 24-hour emergency callouts across South London. Response times vary but we aim to reach you within a few hours for urgent breakdowns.
