How to check if it is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Look for the code 9555507400 marked on the circuit and compare the label with the marking OF:141593 and the software 12.644.05; the commercial reference is 122126440 (also written as 122.126.440).
- Compare the codes with your PCB: other codes and none the 12.644.05.
- Compare the 6-position DIP switch, the terminals N, L, and TA, and the F1 fuse of 3.15 A with those on your PCB.
- Confirm on the rating plate that your boiler is Victoria FF or Neobit 20/20F (confirmed), or Victoria 20/20F or 20/20T. Compare the codes with the Victoria F3 or the Toria FF.
- If they match, call us at 911 17 77 77 with your boiler model and we will reserve it for you.
Symptoms that require diagnosis on the PCB
The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite and locks up on startup, with lights 60-70-90.
Cause: There may be a lack of gas or spark.
Check that there is gas and that the valve is open. If it happens again, have a technician check it.
- 02
The boiler behaves erratically and the lights 40-90 or 50-90 appear.
Cause: Faulty sensor or cable with a loose connection; moisture and rust on the connector cause this symptom.
Check the connector and the cable. If they are fine, have a technician check to replace the sensor or the PCB.
- 03
The boiler does not stop when there is no heating demand, with lights 50-70-90.
Cause: Fault in the safety relay.
Have a technician check it.
- 04
Without domestic hot water or heating, with lock and lights 40-90 or 50-90 on.
Cause: NTC sensor for domestic hot water or heating faulty. The guides do not agree on what code corresponds to each one.
Have a technician check the sensor and its connection.
Fault codes Baxi Roca that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 40-90 | Lights 40 and 90 on: domestic hot water sensor faulty or wiring with a fault. | Check the connector and the cable of the domestic hot water sensor. If they are fine, the sensor or the PCB are the parts to be checked; have a technician inspect it. |
| 50-90 | Lights 50 and 90 on: heating sensor faulty or wiring failure. | Check the connector and the cable of the heating sensor. If they are fine, the sensor or the PCB should be checked; have a technician take a look. |
| 60-90 | Lights 60 and 90 on: the flame relay is not working properly or is off. | If the boiler does not ignite or gets blocked when starting, the PCB (flame relay) is the part to check; have a technician inspect it. |
| 40-60-90 | Lights 40, 60, and 90 on: fault in the safety circuit; the boiler needs to be reset. | Reset according to the manual. If the warning repeats, have a technician check it: it points to the PCB. |
| 50-70-90 | Lights 50, 70, and 90 on: fault in the safety relay, which does not close after the demand. | If the boiler does not stop when there is no demand for heating, have a technician check it: it points to the PCB. |
| 70-90 | Lights 70 and 90 on: safety fuse open. | If the boiler is locked with this warning, have a technician check it: it points to the PCB. |
| 60-70-90 | Lights 60, 70, and 90 on: ignition lock. | Check that there is gas and that the valve is open. If it happens again, have a technician check it: it could be the PCB, the electrode, or the gas valve. |
| 40-50-70-90 | Lights 40, 50, 70, and 90 on: burner off, with very short ignition timing. | If the boiler turns off when starting, have a technician check it: it points to the PCB. |
| 40-60-70-90 | Lights 40, 60, 70, and 90 on: safety relay with very long start-up timing. | If the warning repeats when turning on, have a technician check it: it points to the PCB. |
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.

- To confirm: Baxi Roca Victoria 28/28F — 1 origin: (9555507400, written as "Vitoria")
- To be confirmed: Baxi Roca Toria FF — not confirmed; please check the code on your PCB.
- To confirm: Baxi Roca Victoria F3 — not confirmed; please check the code on your PCB.
- Not compatible or excluded: Baxi Roca Victoria 24/24F — it comes with another PCB: 125568739 (the list with 9555507400)
- Do not confuse: 122156190 — Bleed kit from the Victoria range — Another part: the technical sheet shows it as a related product of the PCB 122126440.
- Do not confuse: 125568739 — PCB of Victoria 24/24 F, 24/24 and 24/24 T — Another PCB: it is given as the original code for those boilers.
