Potterton Boiler Repair London

Potterton is one of the UK’s most established boiler brands, with a history stretching back over 150 years. Now part of the Baxi Group, Potterton boilers are common in older South London properties – particularly the Promax and Titanium ranges – and many are still running well with proper maintenance.

K2 Gas repairs Potterton boilers across Bromley, Beckenham, Lewisham and surrounding areas. Whether your boiler needs a routine service or urgent fault diagnosis, our Gas Safe engineers are available 24 hours a day.

Common Potterton Boiler Fault Codes

  • E119 — Low water pressure. Repressurise to 1–1.5 bar using the filling loop. Recurring pressure loss means there’s a leak to find.
  • E168 — Electrical or PCB fault. Try resetting. If the fault returns, there’s likely a wiring or PCB issue.
  • E133 — Gas supply fault. The boiler can’t detect a gas supply. Check other gas appliances first — if they’re working, this usually points to a faulty gas valve.
  • E160 — Fan fault. The fan isn’t operating correctly. Usually requires fan or wiring replacement.
  • E110 — Overheat lockout. A safety shutdown. Can indicate a pump issue, thermostat fault, or blocked heat exchanger.

Potterton boilers share their control systems with the Baxi range, so fault codes are largely the same. If your boiler is showing a code not listed here, call us.

FAQs

  • My Potterton boiler is old - is it worth repairing?

    It depends on the fault and the boiler’s service history. Potterton boilers are well-built and many older models are worth repairing if the fault isn’t too major. We’ll give you an honest assessment on the day – we’ll only recommend replacement when it genuinely makes financial sense.

  • What does E119 mean on a Potterton boiler?

    E119 is a low pressure fault. Repressure the system to around 1–1.5 bar. If pressure drops repeatedly, there’s a leak in the system that needs tracing.

  • How much does a Potterton boiler repair cost?

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

  • Do you cover emergency callouts?

    Yes – 24 hours a day, across South London. We aim to reach urgent breakdowns within a few hours.
