PCB Saunier Duval Semia Condens F24E / F30E - Code 052.003869/00
The PCB (control board) Saunier Duval Semia Condens F24E / F30E - Code 052.003869/00 is the component that controls the ignition, the modulation of the burner, the pump, and the safety features of the boiler. When it fails, the boiler may not start, become locked, or operate erratically. Users may notice issues such as fault codes F.11, F.18, or F.20. This board is compatible with boilers from the Semia Condens range, such as the F24E and F30E models, among others. It should be replaced when these symptoms or associated fault codes occur.

How to check if the reference 0020021652 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 0020021652. 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 0020021652 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: there are no lights, no display, and no noise from any component.
Cause: The PCB distributes power to the components; if it fails, no current reaches anything.
Check that there is mains voltage at the input connector of the PCB and inspect the internal fuse if it is visible.
- 02
The display or the control shows a fault code that does not disappear even after resetting.
Cause: The electronics block the boiler for safety reasons when detecting an anomaly in a component or in its own reading.
Note the exact code: many point to a sensor, a loose wiring, or an isolated fault, not always to the PCB.
- 03
The boiler turns on and off by itself, or does not respond to the thermostat commands.
Cause: If the microprocessor or the relays on the PCB fail, control over the ignition and shutdown sequence is lost.
First, rule out the thermostat or control: check the batteries, pairing, and ensure that the time or programming is set correctly.
- 04
The display is lit but does not respond when any button is pressed.
Cause: The 5-pin connector that connects the PCB to the display may be loose, dirty, or corroded, interrupting communication.
With the boiler unplugged, disconnect and reconnect that connector and check that no pin is bent.
- 05
A burning smell or dark marks are noticeable when opening the boiler.
Cause: A component of the PCB, such as a capacitor or a relay, has been damaged due to overvoltage or wear and stops performing its function.
With the boiler unplugged, inspect the PCB in good light looking for black spots or swollen parts before replacing it.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.11 | Communication fault between the main PCB and the user interface (display). | The display PCB (0020021652) or its connection cable is not communicating with the main control board. Check continuity and connectors of the harness between the display and the main PCB, and ensure power supply to the interface; if the issue persists, test/replace the interface. |
| F.18 | User interface fault (display PCB). | The display board itself is defective. Check that it is receiving voltage and that the communication cable/bus is correct; if the power supply and wiring are correct, replace the interface module. |
| F.20 | Software incompatibility: incorrect user interface or main board/appliance code error. | An incompatible display board or one with incorrect coding has been installed in relation to the main board/model. Check the appliance code and interface reference in the service menu; reconfigure/update or replace with the correct reference (0020021652 for these models). |
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.
