Chaffoteaux MX2 24 CF PCB - Ariston Thermo Group
When you turn on the tap or activate the heating, the Chaffoteaux MX2 24 CF PCB from Ariston Thermo Group (reference 60003334) is responsible for controlling the entire boiler system. This board manages the ignition, burner modulation, pump, and safety features. If it fails, you will notice that the boiler does not start, locks out, or behaves erratically, potentially displaying fault code 30: Communication fault with the main board. It is compatible with models such as COMPY MX2 24 CF, COMPY MX2 24 FF, MIRA 24 CF, among others. It should be replaced when these faults or operational issues occur.

How to check if the ref. 60003334 is the part 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 60003334. 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 60003334 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 does not start and the display is off or frozen.
Cause: The PCB does not complete its internal startup routine before igniting the burner.
Check that the main switch and the differential switch of the house have not tripped before suspecting the PCB.
- 02
It locks out without any apparent mechanical reason, although the gas and water are functioning well.
Cause: An internal fault in the PCB triggers a safety protection without the actual problem being present.
Reset the boiler and check if the lockout occurs again quickly; if it is immediate, it points more towards the PCB.
- 03
Intermittent fault: sometimes it starts up properly and other times it does not.
Cause: Aged or poorly connected electronic components provide inconsistent responses.
Visually inspect the PCB for any swollen capacitors or burn marks before replacing it.
- 04
The clock or programming of the boiler is lost and needs to be reconfigured.
Cause: A fault in the PCB prevents it from retaining the saved parameters.
Reprogram the time and check if it remains after a short power outage; if it resets on its own without a power cut, point to the PCB.
Fault codes Chaffoteaux that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 30 | Communication fault with the main PCB. | Main PCB fault (60003334) preventing data link with the interface/display module; the unit detects the loss of communication and shows 30. Check voltages and continuity of the bus/wiring to the display; if they are correct and the display works, the 60003334 is faulty. |
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.
