How to check if ref. 122153280 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 122153280. 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 pressure switch 122153280 resolves.

The pressure switch controls the air or water pressure to authorize operation. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  The boiler tries to ignite but shuts off after a few seconds, without burning gas.

  Cause: The pressure switch does not close the contact that indicates there is sufficient draft or depression, so the control board blocks the gas.

  Before replacing it, check that the fan (if your model is forced draft) spins freely and without noise.

• 02

  The fault code or pilot indicates a ventilation or extraction problem.

  Cause: It is the usual warning when the pressure switch does not send the signal that the PCB needs to allow ignition.

  Check that the connection tubes of the pressure switch are not disconnected, crushed, or have accumulated water.

• 03

  The fault is intermittent: some days it starts up fine and other days it gets stuck when trying to ignite.

  Cause: A pressure switch with worn contacts due to use may fail intermittently instead of breaking completely.

  Observe whether the lockout occurs always when cold or only after a period of being on; that pattern helps with the diagnosis.

• 04

  In atmospheric models (without a flue), the blockage occurs especially if it is windy or there are drafts in the flue gas outlet.

  Cause: Without an extractor, the depression depends on natural draft, and an external air current may be enough for the pressure switch not to close the contact.

  Check the flue gas outlet and the natural draft of the duct before considering the part as faulty, especially if your model is atmospheric (A).

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.
