Pressure Gauge Ariston Clas ONE 24 Ref. 65114200
When you open the tap or turn on the heating, the pressure gauge of the Ariston Clas ONE 24 Ref. 65114200 measures the pressure of the circuit. This part is essential for ensuring that the pressure remains within the appropriate values, preventing blockages due to low pressure or issues with temperature regulation. If the pressure gauge fails, you will notice incorrect readings that can lead to inefficient operation of the boiler. It is compatible with models such as Clas ONE 24, Clas ONE 30, Genus ONE Net 24, among others. It is recommended to replace it when you observe that it does not reflect the actual pressure of the system.

How to check if the ref. 65114200 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.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 65114200. 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 and faults that the pressure gauge 65114200 resolves.
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 of the pressure gauge does not move, regardless of the pressure indicated by the circuit.
Cause: The internal mechanism has jammed and does not translate the water pressure into needle movement.
Bleed a radiator for a moment and observe if the needle reacts; if it doesn't move, the pressure gauge is the suspect.
- 02
The needle always stays in the red zone, even after you have filled the system to the correct pressure.
Cause: If after properly filling the circuit the needle remains outside the green band, the fault is usually in the pressure gauge and not in the installation.
Compare the reading with another bleed point or with the pressure gauge of the boiler, if it has one, before confirming the fault of the manometer.
- 03
The boiler indicates a pressure fault even though the circuit is properly filled.
Cause: This part has a cable with a quick connector; if the contact is dirty or not properly fitted, the control board does not receive a signal and locks out for safety.
With the boiler turned off, disconnect and reconnect the quick connector and check that the cable is not pinched before replacing the part.
- 04
The indicated pressure remains stuck at the same number day after day, without changing in either cold or hot conditions.
Cause: It is typical for this type of pressure gauge that the internal mechanism loses elasticity and gets stuck at a value.
Record the cold reading and after a heating cycle; if nothing changes, confirm that it is not responding.
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.
