Pressure Gauge Boiler Neobit Plus / Victoria Plus 24/24 Ref. 125110401
If you notice that the boiler does not regulate the temperature properly or gets blocked due to a false lack of pressure, a technical diagnosis must confirm whether you need a pressure gauge for the Neobit Plus / Victoria Plus 24/24 boiler. This part measures and controls the pressure of the circuit, ensuring it operates correctly. It is installed in the Neobit Plus 24/24, Neobit Plus 24/24 F, and Victoria Plus 24/24 models, among others. A technician must confirm through diagnosis whether it needs to be replaced if you observe incorrect readings or if the boiler is experiencing operational issues.

How to check if the reference 125110401 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 125110401. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms that require diagnosis on the manometer 125110401
The manometer shows the pressure of the boiler circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The needle remains fixed on the dial and does not move even if you bleed or refill the system.
Cause: The capillary or the internal mechanism of the manometer has become blocked and has lost its range.
Gently tap the gauge and fill the circuit with the filling key to see if the needle comes loose.
- 02
Water is leaking from the brass fitting of the capillary tube, even if it's a small amount.
Cause: The gasket of that fitting has deteriorated with the heat cycles and has lost its sealing.
Dry the area of the brass fitting and check when cold and with the boiler on if the moisture reappears at the same point.
- 03
There is no visible pressure on the manometer or the reading does not match what you know about the installation.
Cause: The mechanism has stopped transmitting the actual pressure, even though the circuit is properly filled.
Measure the pressure with a portable manometer at another point in the circuit to rule out that the problem is with the installation and not with this part.
- 04
The needle moves but is slow to respond when you change the pressure.
Cause: The capillary tube may be partially obstructed, causing a delayed pressure transfer to the diaphragm.
Open and close the filling valve slightly and time if the needle takes an unusually long time to respond before replacing the part.
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.
