How to check if ref. S10470 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

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 that require diagnosis on the PCB S10470

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: there is no display, lights, or sound.

  Cause: If the PCB does not receive power, no component works.

  Check if the boiler has mains voltage and if the main switch is on before considering the PCB.

• 02

  Different fault codes appear without repeating the same one.

  Cause: If the microprocessor or an input on the PCB fails intermittently, the alerts change with each attempt.

  Note the codes that appear; if they vary without relation to the operation of the boiler, it is more likely to be the PCB.

• 03

  The thermostat or the control does not manage to activate the boiler.

  Cause: The commands from the control unit go through the PCB before reaching the burner or the pump; if the communication fails, the command is lost.

  Check that the remote control has new batteries and that the bus cable is properly connected before replacing the PCB.

• 04

  The circulation pump does not start even though the boiler requests it.

  Cause: The PCB sends the command to the pump through one of its relays; if that relay fails, the pump does not activate.

  Use a multimeter to check if the pump is receiving power when the boiler should be turning it on; if it is not receiving anything, the command is not coming from the PCB.

Fault codes Saunier Duval that require diagnosis

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.
