Water Pressure Switch Baxi Roca Sara / Nora / Neobit Ref. 122153280
Water pressure switch manufactured by Vergne Innovation (manufacturer reference 121110-0026), installed in Baxi Roca boilers from the Neobit, Nora, and Sara ranges. It monitors the water circuit pressure and shuts off the flow upon detecting an anomaly, preventing the boiler from operating with insufficient pressure. It is replaced when it intermittently shows a pressure fault or stops making contact.

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.
- Locate the reference printed on the body of the pressure switch you have installed: it should indicate 122153280.
- Check your boiler model on the nameplate and look for it in the list of compatible models on this page.
- Compare the connections and the body with the original part before installing.
- If you have any doubts, send us a photo of the screen printing via WhatsApp and we'll confirm it for you before you purchase.
Symptoms and faults resolved by pressure switch 122153280
The pressure switch controls the air or water pressure to authorize operation. These are the typical symptoms and what to do:
The boiler won't start and shows a water pressure fault even though the circuit is properly filled.
Cause: The pressure switch monitors the circuit pressure and shuts off the flow upon detecting an anomaly; if the component itself fails, it may indicate a lack of pressure even when the circuit is correct.
Check the pressure gauge before changing anything: if the pressure is within the normal range and the fault persists, the pressure switch is the main suspect.
The pressure fault is intermittent: it appears one day and not the next.
Cause: A pressure switch that does not close or open the contact properly due to wear can give inconsistent signals even if the circuit pressure does not change.
Note if the fault coincides with sudden temperature changes or with the use of domestic hot water; if there is no clear relation, point to the pressure switch.
The boiler locks out just when requesting heating or domestic hot water, even though it was working fine a moment before.
Cause: The pressure switch can fail at the moment the pump starts or the demand increases if the contact is on the verge of making a good closure.
Pay attention to the exact moment it locks (when requesting heat, when the circulator starts) and compare it with the reading on the pressure gauge at that instant.
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.

- Reference 122153280 is the reference used by Baxi Roca to identify the part; the actual manufacturer (Vergne Innovation) uses its own reference, 121110-0026, printed on the label. This is not a discrepancy; they are two different reference systems: make sure your part matches one of the two before ordering.
