SIT PCB La Precisa Sime Brava DGT HE 25 Ref. 7330210_03
Sime Brava DGT HE offers the SIT La Precisa PCB, which controls the ignition, burner modulation, pump, and safety features of the boiler. If it fails, you may notice that the boiler does not start, locks out, or exhibits erratic behavior. This board is compatible with the Brava DGT HE 25, 30, and 35 models, as well as the Open DGT EV HE 25, 25/40, and 30. You should consider replacing it if you experience issues such as fault code AL 10, which indicates performance failures, or AL 13, which indicates that the fan is not functioning properly.

How to check if the reference 6301485 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 6301485. 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 6301485 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 is completely dead: it doesn't turn on or display anything.
Cause: Without the control board, there is no ignition management, even if power and gas reach the unit.
Check the boiler's input fuse and the main switch before replacing the PCB; first rule out a simple power outage.
- 02
A fault code is triggered and the boiler locks out even after being reset multiple times.
Cause: The PCB interprets a signal from a sensor (pressure, flame, temperature) as abnormal and interrupts the cycle for safety.
Identify the fault code before purchasing; if it points to a specific sensor, check that component first instead of the PCB.
- 03
The circulation pump or the gas valve do not activate even though the boiler requests heat.
Cause: The output relay on the PCB that controls that component may stop switching even though the rest of the functions remain operational.
With a tester, measure if there is power at the connector of the pump or the gas valve when the boiler demands; if there is no power, the problem is in the PCB.
- 04
The boiler restarts by itself or loses its programming from time to time.
Cause: An internal fault in the PCB (memory, capacitor, soldering) can cause restarts without an actual power outage.
Make sure that the boiler is plugged into a stable outlet and that there are no other devices causing micro-cuts before attributing it to the PCB.
Fault codes for Sime that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| AL 10 | Boiler performance issues. | This code indicates that the auxiliary sensor is not functioning properly. It may be due to a fault in the PCB that affects the sensor reading. Check the PCB and make sure it is in good condition. |
| AL 13 | The fan is not working as it should. | This code indicates that the fan is not functioning as it should, which can affect the evacuation of combustion gases. A fault in the PCB can prevent the fan from receiving the correct signal. Check the PCB and the fan. |
| AL 14 | Problems with the flue sensor. | This code indicates that the flue gas sensor is not functioning properly. It may be due to a fault in the PCB that affects the reading of the sensor. Check the PCB and the flue gas sensor. |
| AL 15 | The fan is experiencing a problem. | This code indicates that the fan has a problem that prevents it from functioning properly. A fault in the PCB can affect the signal received by the fan. Check the PCB and the condition of the fan. |
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.
