Baxi 100/2 HE Electronic Control PCB – Refurbished | Part No. 5121025

Loss of heating, ignition failure, and no hot water in a Baxi 100/2 HE, Solo HE, or HE Plus boiler most often point directly to a failing electronic control PCB. The board manages every key function — ignition sequencing, heating and DHW control, safety interlocks, and sensor communication. The Baxi 100/2 HE Electronic Control PCB (Part No. 5121025) is the correct refurbished replacement for the 100/2 HE, Combi HE Plus, Solo HE / Solo IE, and HE Plus heat-only ranges, restoring complete boiler control.

This is a professionally refurbished genuine Baxi component — fully tested to OEM performance standards before dispatch. Available for Combi and System boiler variants. Minor cosmetic marks may be present. Supplied with a full 12-month warranty.
