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 start at all: no display, no fan, no noise when pressing the power button.

  Cause: If the PCB does not receive power, it cannot supply any circuit of the unit.

  Check that the boiler receives 230V from the mains and that the main switch and the fuse of the PCB are in good condition before replacing it.

• 02

  A fault code appears on the display that doesn't disappear even after resetting the boiler.

  Cause: The microcontroller on the PCB detects abnormal signals and locks the unit for safety, displaying a fault code.

  Note the exact code and check the sensor or component related to that fault before replacing the PCB.

• 03

  The remote control or the room thermostat is unable to communicate with the boiler, or does so intermittently.

  Cause: A fault in the PCB can interrupt communication with the control, even if the rest of the equipment is functioning correctly.

  Check the communication bus wiring and test the boiler in manual mode, without the remote control, to rule out other issues.

• 04

  The boiler runs for a while and then stops on its own, without a clear pattern of when it happens.

  Cause: Solder joints and traces on the PCB can fail due to heat, causing micro-cuts that the electronics interpret as a fault.

  Observe if the cut occurs consistently at the same phase of the cycle (start, modulation, stop) before concluding that the PCB is faulty.
