Main PCB Biasi Mura 24E (ver.09)
If the boiler does not start, locks out, or exhibits erratic behavior, a technical diagnosis must confirm if you need the main PCB (control board) Manaut Mura 24E (ver.09) from Bertelli & Partners, reference BI2075105. This part controls the ignition, burner modulation, pump, and safety features of the boiler. It is installed in models such as the MINOX ECO 24E, MURA 24E (ver.09), among others. A technician must confirm through diagnosis whether it needs to be replaced upon noticing these symptoms, as its failure can severely affect the operation of the boiler.

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.
- Find the reference printed on the installed part and check whether it matches the catalogue reference —. If it is not visible, do not identify the part by 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
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: neither the display nor any indicator lights up.
Cause: A fault in the internal power supply or in the microcontroller of the PCB prevents the boiler from operating.
Check the internal fuse and verify that power is reaching the PCB before replacing it.
- 02
The boiler restarts by itself or fails to turn on when other electrical appliances in the house are used.
Cause: The EMC filter on the PCB protects against electrical interference; if it deteriorates, the board may become sensitive to those spikes.
Try connecting the boiler to another socket or different circuit before considering the PCB as faulty.
- 03
The boiler ignites, but the pump or the fan do not operate when they should.
Cause: The relays that power these components are part of the circuit of the PCB.
Check if there is power to the pump and the fan at the moment they should activate, before replacing the PCB.
- 04
You press the reset button and the boiler does not respond, it remains locked.
Cause: If the microcontroller does not detect the press, the reset will have no effect.
Check that the reset button is not mechanically stuck before replacing the PCB.
Fault codes Biasi that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 11E | An unwanted flame has been detected. | A unwanted flame has been detected. This may be caused by a fault in the PCB that is incorrectly interpreting the flame signal. Ensure that the system is safe and check the burner; if everything is correct, the PCB may be the cause of the problem. |
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.

Part data and available documentation
Contrast the label codes, PCB, and revision with the installed part; they are not necessarily equivalent references.
- Printed circuit board code (silkscreen)
- HDTMS08
- EMC filter installed
- Schaffner 10RE14-L.HBT (filter brand, does not confirm the manufacturer of the PCB)
- Barcode on B&P label
- 051223311671
- The EMC filter is branded Schaffner, but that identifies the manufacturer of the filter, not necessarily that of the complete PCB.
