How to check if ref. 122420630 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 122420630. 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 122420630

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 display or indicators of the boiler are flashing or showing incoherent information.

  Cause: A fault in the control board causes incorrect readings that are directly reflected in the information displayed to the user.

  Note what the display shows exactly and when it changes, and check that the connectors of the display itself are properly fitted to the PCB.

• 02

  The room thermostat is not able to start the boiler.

  Cause: The PCB is the one that receives the command from the thermostat and decides whether to start; if its input circuit fails, the command is lost.

  First, check that the thermostat is working with new batteries and that the cable is properly connected to the corresponding terminals on the PCB.

• 03

  The boiler locks out with different fault codes without a clear pattern.

  Cause: The electronics of the PCB poorly manage the signals from the safety sensors and cause lockouts that do not always correspond to those components.

  Record the codes that appear and discard the pressure switch and NTC by checking their continuity with a multimeter.

• 04

  The boiler does not ignite at all, with no indicator lights or sound.

  Cause: The power supply stage of the PCB, or the fuse that protects it, has stopped delivering current to the electronics.

  Check with a multimeter that power is reaching the input of the PCB and visually inspect the condition of the fuse before replacing it.

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.
