PCB Biasi Malia 28 E Ref. M800109
The Biasi Malia 28 E PCB (control board) Ref. M800109 controls the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, become locked, or exhibit erratic behavior. This part is compatible with several models, including the Minox 24 E, Minox 28 E, Minox 32 E, Micon 24 E, and M90.24 CM/B, among others. It is recommended to replace it when you notice these symptoms, as its malfunction affects the performance of the boiler.

How to check if the part number BI1305101 is the one for your boiler.
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- 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 and faults that the PCB BI1305101 resolves.
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's remote control or panel does not respond to the presses.
Cause: The PCB manages the communication with the control. If the microcontroller fails, that communication is lost.
Disconnect and reconnect the remote control cable. Check that it is not damaged before considering the PCB as lost.
- 02
The pumps or the fan do not start even though the boiler requests heat, and they work if you force them manually.
Cause: The relay output of the PCB that should activate that component may not be switching.
With the boiler calling for heat, measure if there is power at the connector going to the pump or the fan.
- 03
The boiler turns on and off by itself repeatedly, not coinciding with the normal heating cycles.
Cause: A faulty output relay with a damaged contact intermittently cuts off power to a component.
Check that the connectors on the PCB are properly seated, with no loose pins or corrosion.
- 04
There is a burnt smell or dark marks on the PCB when opening the boiler.
Cause: An internal short circuit or a component damaged by overvoltage disables the electronics.
Inspect the PCB visually with the boiler disconnected before confirming the replacement.
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.
