How to check if ref. 0020212697 is the part for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 0020212697. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the PCB 0020212697 resolves.
The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.63 | EEPROM memory fault of the boiler's electronic control. | The EEPROM resides in the main PCB itself (this piece); a read/write fault in its memory originates from the electronics. It is checked by ruling out interference and, if it persists after restarting, by replacing the PCB. |
| F.64 | Fault in the electronics related to the NTC sensor input. | The processing of the NTC signal is done by the PCB; with the short circuit in the NTC flow/return sensor ruled out (measure the sensor's resistance), the remaining documented cause is a fault in the electronics/PCB itself. |
| F.65 | Electronic temperature fault (PCB overheating). | It is detected and caused by the PCB itself; first verify that there is no external source of abnormal heat and, if ruled out, the code indicates a fault in the electronics/PCB. |
| F.67 | Electronics/flame fault: flame signal not plausible for the control. | The flame signal detection and validation circuit is on the PCB; when the received signal is not plausible and the ionisation electrode is ruled out, the documented cause is an electronics/PCB fault. |
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
