| Code | Meaning | Fix level |
|---|---|---|
1also: 01 | The boiler gets too hot: the heat cannot be carried away (insufficient flow) | DIY checks first |
10 | Flow sensor S1 is open circuit (no signal) | DIY checks first |
11 | Short circuit in flow sensor S1 | Call a professional |
12 | Flow sensor S1 reads a sudden temperature drop of 10 °C within 1 second | Call a professional |
13 | Flow sensor S1 reads a sudden temperature rise of 10 °C within 1 second | Call a professional |
14 | Flow sensor S1 reads no temperature change while the boiler is operating | Call a professional |
2also: 02 | Flow and return sensors (S1 and S2) are in the wrong location or swapped | Call a professional |
27 | Short circuit in the outdoor sensor (outside temperature sensor) | Call a professional |
29 | Gas valve relay fault (ignition module) | Call a professional |
30 | Gas valve relay fault (PCB or wiring to the gas valve) | Call a professional |
4also: 04 | No flame signal: the burner does not ignite or the flame is not detected | DIY checks first |
5also: 05 | Poor flame signal: the flame is not detected properly while burning | DIY checks first |
