How to check if the part number BI1305101 is the one 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 BI1305101. 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 BI1305101
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 pump or circulator never stops, even when there is no demand for heating.
Cause: A relay on the PCB has stuck and keeps the output active.
Turn off the boiler completely for a couple of minutes and then turn it back on; if it continues to circulate while off, it points to a stuck relay.
- 02
It doesn't turn on and doesn't show any fault code on the display.
Cause: The PCB does not start the ignition cycle due to a fault in its control stage.
Check that the water pressure switch and the safety thermostat are not in cut-off before replacing the PCB.
- 03
The display shows a fault code that comes and goes, it is not constant.
Cause: An internal contact on the PCB is intermittently failing due to moisture or vibration.
Check that all the connectors on the PCB are properly fitted; a loose terminal gives the same symptoms as a damaged board.
- 04
The boiler works but with rare power cuts, as if it loses and recovers power on its own.
Cause: A component on the PCB is intermittently failing during the power supply stage.
Check the electrical installation of the boiler (socket, plug, control panel) before assuming it is the PCB.
Fault codes Biasi that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 01E | The boiler does not ignite. | The boiler does not ignite. This may be caused by an issue with the PCB that prevents the ignition from functioning properly. If you have checked the gas supply and the igniter, you may need to inspect the PCB. |
| 06E | The heating NTC sensor is failing. | The heating NTC sensor is failing. If you have checked the sensor and its connection, it is possible that the issue lies with the PCB, which is not processing the information from the sensor correctly. |
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.
