How to check if it is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference —. If it is not visible, do not identify the part by 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.
What to check before replacing the PCB (control board)
Common symptoms and faults
- 01
The boiler is completely off, with no indicator lights or display.
Cause: The PCB is not receiving or distributing power to the rest of the control circuit.
Check that there is voltage at the boiler's power supply and that the main switch is in the correct position before replacing the PCB.
- 02
A fault code appears and reappears immediately after resetting.
Cause: The PCB shuts down the operation because a safety signal is outside the expected values.
Identify the code and check the associated component (flame, pressure, sensor) before blaming the PCB.
- 03
Clicking sounds from a relay on the PCB can be heard even though the boiler does not start.
Cause: A relay with poor contact, like the one marked on the label of this PCB, tries to switch without succeeding.
Listen to see if the clicking coincides with the moment of the heat demand; if so, the relay on the PCB is suspect.
- 04
The electronic control does not respond to any button on the panel.
Cause: The microcontroller on the PCB has locked up and stops processing commands.
Cut the power for a few seconds to force a complete reset before replacing the PCB.
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.
