Description

Baxi Pump PCB Replacement 7222704

The Baxi 7222704 relay PCB (refurbished) is a genuine OEM boiler component used across a wide range of modern ErP-rated combi and system boilers. The relay PCB works alongside the main control board to switch and control key boiler components such as pumps, fans, and valves.

A failed relay PCB can cause symptoms including intermittent boiler operation, components not activating, heating or hot water faults, or unexplained lockouts. Replacing the faulty board with this Baxi 7222704 relay PCB restores correct electrical switching and reliable boiler performance.

Each refurbished unit is professionally inspected, cleaned, and fully tested to ensure correct operation, offering a cost-effective alternative to buying new. Installation and commissioning must always be carried out by a Gas Safe registered engineer. Compatibility is serial and issue specific, so checks are essential before ordering.
