Potterton Gold Fault Codes
The Potterton Gold was the brand's better-specified range of the 2010s — combi, system and heat-only versions a step above the Promax, with the same Baxi-group platform underneath and therefore the same E-code fault language: E119 pressure, E133 ignition/gas, E110 overheat and the rest. Golds are now comfortably into mid-life, and their fault pattern is the platform's: preventable water-quality codes and seasonal condensate trouble ahead of genuine component failures. Parts commonality with the wider Baxi/Potterton fleet keeps repairs quick and affordable. The codes below link through to full diagnosis pages.
Where Gold fault codes appear
The Gold shows E-prefixed fault codes on its fascia display in place of the temperature reading, flashing on lockout. Record the exact number before resetting — neighbouring codes lead to different components on this platform.
Resetting a Potterton Gold
Press and hold the reset control briefly; the boiler retries. E119 wants a top-up to 1–1.5 bar at the filling loop first, and winter E133s want the condensate pipe checked and thawed before any reset. One reset is information; repetition is avoidance.
Common Gold problems
Mid-life Golds log the group staples — E119 pressure weeps, E133 ignition with its condensate accent, circulation codes where filters and inhibitor were skipped — plus the first sensor and fan retirements of age. These are straightforward boilers to keep healthy: water treatment and the annual service carry most of the load.
