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 light up any indicator, it is completely off even though there is power at the outlet.

  Cause: The main PCB manages all the power supply and control of the boiler, so its failure leaves everything unresponsive.

  Before replacing it, check the fuse of the PCB and the main circuit breaker; they are the most common cause of this symptom and cost nothing to check.

• 02

  The control works but the boiler does not execute the command: it neither ignites the burner nor moves the pump.

  Cause: The microcontroller on the main PCB receives the request but does not activate the startup sequence.

  Perform a full reset by cutting the power for one minute and check that the PCB connectors are not loose or corroded.

• 03

  A new, unusual fault code appears, or it changes every time an attempt is made to reset the boiler.

  Cause: The damaged control electronics cause incorrect readings from the sensors, generating fault codes that do not reflect the actual problem.

  Write down the exact code and check it in the manual before deciding: it may point to a sensor and not to the PCB.

• 04

  The boiler shuts off on its own after being on for a while, without following a clear pattern of use or time.

  Cause: An intermittent fault in the PCB, such as a cold solder joint, causes cuts that do not always correspond with the same warning.

  Note if the shutdown always occurs when a specific component starts (pump, fan): if so, check that component first.

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.
