Baxi 5121025 PCB (Refurbished) | HE, HE Plus & Solo Boilers

Description

Baxi 5121025 Electronic Control PCB – Refurbished Genuine Boiler Control Board

The Baxi 5121025 electronic control PCB (refurbished) is a genuine OEM boiler control board used across a wide range of Baxi heat-only, system and combi boilers. The PCB is the boiler’s central control unit and manages ignition sequencing, flame supervision, pump control, temperature regulation, and all core safety functions.

When a PCB fails, boilers may experience lockouts, no heating or hot water, intermittent faults, or unresponsive controls. Replacing the faulty unit with this Baxi 5121025 PCB restores stable boiler operation and reliable performance.

Each refurbished PCB is professionally inspected, cleaned, and fully tested to confirm correct operation, offering a cost-effective alternative to buying new. Installation and commissioning must always be completed by a Gas Safe registered engineer. Compatibility should be confirmed using the boiler data badge.
