PCB Boiler 23 MFFI - Code CB3-FFI02 / 000095233201
The control PCB CB3-FFI02, with reference 000095233201, regulates 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 models such as New Basic 23 MFFI and Eurocombi AT 23 MFFI, among others. It is recommended to replace it when these symptoms occur, as its malfunction affects the proper performance of the boiler.

How to check if the part number 953332 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 953332. 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 953332 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 turn on at all: there are no lights and it does not respond to pressing anything.
Cause: The PCB manages the ignition; if it fails, there is no response at all.
Check the fuse on the PCB and verify that it is receiving power before considering it faulty.
- 02
The burner ignites briefly and then turns off immediately, as if it cuts out by itself.
Cause: A fault in the electronic management can interrupt the flame maintenance signal when starting.
Before changing the PCB, make sure that the flame detection electrode is clean and properly positioned: a dirty electrode can cause the same problem.
- 03
A fixed fault code appears on the display that does not clear when resetting the boiler.
Cause: The PCB keeps the lock because it continues to detect the same fault every time an attempt is made to turn it on.
Note the code and compare it with the manual: some codes indicate problems with the sensor or the pressure switch, not with the PCB.
- 04
The control or the thermostat do not affect the boiler, as if they were not connected.
Cause: If the PCB does not correctly process the signal from the thermostat, the boiler ignores the on and off commands.
Check the thermostat connection on the terminal block of the PCB and try bridging its terminals to see if the boiler responds.
Fault codes for Ariston that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 3 07 | Fault in the main PCB | There is a problem with the main PCB. This can cause a malfunction of the boiler, such as not igniting or not maintaining the proper temperature. |
| 3 05 | Fault in the main PCB. | A fault has been detected in the main PCB. This may affect the performance of the boiler, causing it not to operate as it should. |
| 3 06 | Fault in the main PCB. | The main PCB is failing. This can cause the boiler to not operate properly, resulting in heating issues. |
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.
