PCB Baxi Roca Neobit S 24/24 F Honeywell Ref. 125568548
The Roca Neobit S 24/24 F Honeywell PCB is the component that controls the ignition, the modulation of the burner, the pump, and the safety features of the boiler. If this part fails, the boiler may not start, become locked, or exhibit erratic operation. This model is compatible with boilers from the Neobit S range, such as the Neobit S 24/24 and the Neobit S 24/24 F, as well as with some models from the Main range, such as the Main 24 i and the Main 24 Fi. A technician must confirm through diagnosis whether it is necessary to replace the PCB upon detecting these issues to restore the normal operation of the boiler.

How to check if ref. 125568548 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 125568548. 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 125568548
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 shows no signs of life on the control panel.
Cause: This module manages the start-up and safety of the boiler; if it fails, there is no response at all.
Check if there is power to the PCB and make sure that the fuse is not blown before replacing it.
- 02
The room thermostat is calling for heat, but the boiler does not start.
Cause: The PCB receives the demand from the thermostat and commands the ignition; a fault at this stage leaves the demand unanswered.
Do not bridge contacts or power components directly to test them. Request a technician to check the cause according to the model manual and its revision, without bypassing the protections. The symptom or fault code does not confirm on its own that this part is faulty.
- 03
The panel controls are unresponsive or behave erratically.
Cause: The module integrates the keyboard control; an internal fault prevents the key presses from being executed.
Check that the flat keyboard connector to the PCB is properly seated before replacing it.
- 04
Intermittent fault: the boiler works for a few days and then stops without a clear fault code.
Cause: A problem in the internal power transformer of the PCB can cause an unstable secondary current to the entire electronics.
Note if the fault coincides with vibrations or impacts on the boiler; if so, it points to a loose solder joint before 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.
