How to check if ref. S10470 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.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference S10470. If it is not visible, do not identify the part from its shape alone.
2. Check the full boiler model on its data plate and look for it in the model associations on this page.
3. Compare the connections and physical body with the original part before installation.
4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

Symptoms and faults that the PCB S10470 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 any function, neither heating nor domestic hot water.

  Cause: The PCB is not managing any of its outputs due to a widespread internal fault.

  Check that the correct voltage is reaching the PCB and that no fuse has blown before replacing it.

• 02

  A fault code is displayed that does not match any visible problem with the boiler.

  Cause: The control electronics misinterpret a signal and displays a fault that is not real.

  Note the exact fault code and reset the boiler once before declaring the PCB faulty.

• 03

  The flame modulates erratically, rising and falling without any change in the heating demand.

  Cause: The PCB is not properly regulating the signal it sends to the gas valve.

  Check the condition of the gas valve and its wiring before blaming the PCB.

• 04

  The remote control or the control panel does not synchronize with the boiler.

  Cause: There is a communication failure between the PCB and the control module.

  Check the data bus connection between the PCB and the control before replacing the PCB.
