How to check if ref. 122460020 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 122460020. 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 122460020 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 indicates a pressure fault even though the flue appears normal.

  Cause: The sensor sends an incorrect signal to the control board, which is not within the acceptable range.

  Check that the wiring of the sensor is not frayed, cut, or making poor contact.

• 02

  The burner does not ignite even though the extractor is functioning properly.

  Cause: If the sensor does not send a valid signal, the control board does not allow the gas valve to open.

  If you have a multimeter, measure the output current of the sensor; if it doesn't change when starting the fan, the problem is there.

• 03

  The pressure fault appears intermittently, not always at the same point in the cycle.

  Cause: A sensor gives unstable readings if its membrane or internal circuit is damaged.

  Check the silicone tubes of the sensor for any cracks, disconnections, or condensation.

• 04

  The pressure switch trips more often depending on the weather conditions or the installation.

  Cause: Variations in external pressure can cause an old sensor to give incorrect readings.

  Note the conditions under which the fault occurs before deciding whether it is the sensor or something related to the flue.
