Chaffoteaux Siam 2 23 E FF Control Board Ref. 61002907
The Chaffoteaux Siam 2 23 E FF PCB (control board) is a component that controls the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, become locked, or operate erratically, displaying faults such as 3 03, 3 05, 3 06, or 3 07. This board is compatible with the Siam 2 23 E FF boiler, among others. It should be replaced when these symptoms or faults indicating malfunction are detected.

How to check if ref. 61002907 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 61002907. 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 61002907 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 shows no signs of life: no display, no indicator light, even though there is power in the house.
Cause: If the power PCB fails, the control PCB does not receive power even if it is in good condition.
Check that the fuse on the PCB is not blown and that power is reaching the input before replacing the assembly.
- 02
A different fault code appears each time, with no clear relation to water, gas, or draft.
Cause: An internal fault in the assembly of PCBs causes errors that point to healthy components.
Note the codes that appear during several startups: if they change without a pattern, the problem lies in the electronics and not in the indicated part.
- 03
The relays click but the pump or the fan do not start
Cause: The power PCB receives the command from the control PCB but does not deliver current to the output.
With a multimeter, check if there is power at the connector of the pump or the fan at the moment it should be activated.
- 04
The control or the panel does not respond to any button presses.
Cause: If the control board gets locked, the panel stops responding to user commands.
Cut the power to the boiler for 2-3 minutes and try again before declaring the PCB as faulty.
Fault codes Chaffoteaux that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 3 03 | Main PCB fault | The control board (PCB) fails internally (memory/CPU/power supply) and the unit locks with 3 03; check 230 V input and 5/12 V on the PCB, BUS connectors, and rule out with a known/test bench board. |
| 3 05 | Main PCB fault | Fault in the control board preventing correct operation; confirm voltages and communication, inspect tracks/relays, and verify by temporarily replacing the PCB. |
| 3 06 | Main PCB fault | Internal fault of the regulation PCB (control/services of the board); measure stable 5/12 V, check connectors and rule out fault by testing with another board. |
| 3 07 | Main PCB fault | Fault in the control board detected by self-diagnosis; check power supplies/regulators, connections, and confirm by replacing the PCB 61002907. |
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.
