How to check if ref. S1019000 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 S1019000. 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 S1019000

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 is completely dead, not even a pilot light is on.

  Cause: A fault in the transformer or in the fuse of the PCB cuts off power to the rest of the circuit.

  Measure with a multimeter if the fuse on the PCB is blown before considering the board as lost.

• 02

  It turns on for a moment and then turns off, repeating the cycle over and over again.

  Cause: The PCB aborts the startup at a specific point in the sequence due to an internal control fault.

  Check at what exact moment it cuts off, before the flame, with the flame, or when modulating, to determine if it is the PCB or another component.

• 03

  The boiler control does not respond to temperature changes.

  Cause: The microcontroller on the PCB does not properly manage the signal received from the thermostat.

  Do not force, hit, or bridge the component. Request a technical check according to the equipment manual before deciding on its replacement.

• 04

  An error code appears that repeats after each reset attempt.

  Cause: The PCB detects a persistent internal fault and does not allow the ignition cycle to proceed.

  Note the code displayed before purchasing, to verify that it corresponds to a PCB fault according to your boiler's manual.

• 05

  The boiler does not ignite: the room thermostat flashes with fault code 01 or 04.

  Cause: The burner does not ignite or the flame is not detected. There may be a lack of gas.

  Press the thermostat button and follow its instructions. If it appears again, have a technician check it.
