How to check if ref. S1047000 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 S1047000. 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 S1047000 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, not even a single indicator light, as if it is not receiving power.

  Cause: The PCB may have a blown input fuse or a damaged power circuit, cutting off the supply to all the electronics.

  Make sure that the boiler is receiving power (plug, circuit breaker, installation fuse) before declaring the PCB dead.

• 02

  A fault code appears on the screen that comes and goes, without a clear pattern.

  Cause: An intermittent fault on the PCB, due to cold solder joints or damaged traces, generates errors that do not always repeat in the same way.

  Note the exact code and try resetting the boiler to see if the fault reappears before changing the PCB.

• 03

  The remote control or the thermostat is unable to communicate with the boiler.

  Cause: The communication stage of the PCB may have failed, leaving the dialogue with the control unit cut off.

  Check the wiring connection of the control panel on the terminal block of the PCB before replacing it.

• 04

  The boiler turns on and off by itself without anyone touching the thermostat.

  Cause: A relay on the PCB that does not cut off properly can erratically activate the burner or the pump.

  Listen for the clicks of the relays when starting up and check if they match with turn-ons that you did not request.
