Pressure gauge Baxi Roca Sara / Nora / Neobit 24/24 Ref. 122156310
Analog pressure gauge, scale 0-4 bar, for Baxi Roca Neobit, Nora, and Sara 24/24 F boilers. According to sources, the same reference (122156310) is used in all three models. It indicates the pressure of the heating circuit; it is replaced when the needle gets stuck, shows an incorrect pressure, or stops moving completely.

How to check if ref. 122156310 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 gauge you have installed: it should indicate 122156310.
- 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 gauge 122156310
The pressure gauge shows the pressure of the boiler circuit. These are the typical symptoms and what to do:
The needle gets stuck at one point and does not respond even if the circuit pressure changes.
Cause: The internal bellows of the pressure gauge have seized or broken, and it no longer transmits the actual pressure to the needle.
Bleed and refill the circuit using the filling key while observing the needle; if the water enters with pressure and the needle does not move, the pressure gauge is faulty.
The pressure gauge shows a pressure that doesn't match what you know the system actually has.
Cause: The internal spring becomes uncalibrated over the years or due to a pressure surge, and the needle remains displaced even though the mechanism still moves.
Bleed the circuit a little and check if the needle drops proportionally; if it moves but doesn't match the pressure it should have, confirm the fault before replacing it.
You can't rely on the reading to know when to stop filling or bleeding the circuit.
Cause: If the mechanism fails, it ceases to serve as a reliable reference even if the boiler operates normally.
Compare the reading with the pressure the circuit should have when cold (usually between 1 and 1.5 bar); if it doesn't match even after bleeding, the pressure gauge is the problem.
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.
