Fault codes Baxi that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 125 | Lack of circulation in the primary circuit (safety activation due to gradient/excess temperature). | If the 3-way valve with bypass gets stuck or its motor does not switch, the flow is diverted or blocked, and the boiler detects a lack of circulation and overheating; check that the 3-way valve changes position and receives ~230 V at the motor according to the wiring diagram (section K of the service manual). |
