Bertelli & Partners PCB HAGC03-BX01 · Baxi Roca Neodens Plus 28/28 F
Control board of Baxi boiler: it controls the gas valve and communicates with the control unit. The initial messages E55 or E53 require calibration. In case of E09, the cable and connector of the gas valve should be checked; for E83 to E87, the cable between the control unit and the PCB or the RF link. With E15, the cable is checked and the PCB is replaced if the diagnosis requires it.

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.
- Look for the silkscreen "HAGC03 - BX01" and the circuit code 17258.04 on the PCB.
- Also check 7728901. Our unit also has 10240943100829 and "WK 06/25".
- Compare the codes on the PCB, not just the boiler, and ensure the suffix is BX01.
- If they match, call us at 911 17 77 77 with your boiler model and we will reserve it for you.
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
E09 or E15: gas valve fault
Cause: Check the cable between the PCB and the gas valve (with E09, also the connector); with E15 the manual allows changing the PCB.
- 02
E83 to E87: no communication
Cause: Check the cable between the control unit and the PCB, or the RF link.
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.
