PCB Baxi Roca Victoria 24/24 F Ref. 125568739
The control PCB of the Baxi Roca Victoria 24/24 F manages the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, become locked, or behave erratically, displaying fault codes such as E99, E98, or E35. This part is compatible with several models in the Victoria range, including the Victoria 20/20 and the Victoria 24/24, among others. A technician must confirm through diagnosis whether it needs to be replaced when the mentioned symptoms or operational errors occur.

How to check if the reference 125568739 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 125568739. 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 that require diagnosis on the PCB 125568739
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 turn on, there are no lights or display.
Cause: The PCB is not sending current to the rest of the electronics.
Check if the fuse on the PCB is blown before replacing it completely.
- 02
The remote control or the control panel do not respond, even though the boiler is on.
Cause: The PCB has lost communication with the control electronics.
Turn off the power to the boiler, wait a minute, and turn it back on to rule out a temporary fault before replacing the PCB.
- 03
The boiler turns on and off by itself intermittently, without a clear pattern.
Cause: A fault in the PCB causes erratic control of the ignition or safety.
Note whether the fault occurs when using domestic hot water, heating, or both, before deciding that it is the PCB.
- 04
An error code appears on the display that does not clear after resetting the boiler.
Cause: The PCB detects an internal or communication fault and keeps it locked.
Check the boiler manual to find out which component indicates that code before assuming it is the PCB.
- 05
The relay clicks but the boiler does not respond.
Cause: The relay works, but the output to the component has no effect.
With the boiler unplugged, check that the connectors on the PCB are properly fitted and free of rust before replacing it.
Fault codes Baxi Roca that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| E99 | Communication fault between micros or PCB error | The PCB fails in its self-diagnosis/internal communication (between microcontrollers) or with managed elements; check polarity, grounding, and voltages, and if the issue persists, confirm communication lines or test with a known PCB. |
| E98 | Communication fault between micros or PCB error | The PCB shows an internal communication fault (parameters/EEPROM/firmware) that blocks the electronics; check power supply, grounding, and parameter settings after changing the PCB (e.g. F03/F12) and, if not corrected, replace or reprogram the PCB. |
| E35 | Parasite flame (flame error) | The flame detection stage on the PCB interprets a spurious signal due to leaks/currents or a fault in the ionization circuit; check the ionization electrode and ground, moisture on the board, and if it persists, measure the signal and test/a technician must confirm whether to proceed with replacing 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.
