Ariston AS 24 FF Pressure Gauge Ref. 65104234
The Ariston AS 24 FF manometer is a device that measures and controls the pressure of the boiler circuit. If it malfunctions, you will notice incorrect readings, which can cause the boiler to lock out due to a false low pressure or fail to regulate the temperature properly. This manometer is compatible with several Ariston boilers, such as the AS 24 CF and AS 24 FF models, as well as those from the BS, CLAS, EGIS, GENUS, and MATIS ranges, among others. It is recommended to replace it when it starts to show inaccuracies in the readings.

How to check if ref. 65104234 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 65104234. 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 65104234 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 does not indicate pressure or gets stuck at one end, not moving even if the actual pressure changes.
Cause: The internal mechanism has jammed and does not transfer the circuit pressure to the needle.
Fill the circuit with the filling key until it reaches 1-1.5 bar and check if the needle reacts to the change.
- 02
The gauge is fogged on the inside or broken, and the scale from 0 to 4 bar cannot be distinguished.
Cause: Moisture has entered the body of the pressure gauge or the glass has been hit.
Check if the condensation is only on the outer glass or also between the glass and the sphere, to determine if it's a cleaning issue or a fault.
- 03
Water is dripping from the base of the pressure gauge, where it connects to the boiler.
Cause: The gasket or the thread of the base has lost its seal over time and use.
Dry the area well and observe for a few minutes with the boiler running to confirm that the drop is coming from the base and not from another nearby fitting.
- 04
The pressure seems normal at first glance, but the boiler is still showing a pressure fault.
Cause: The pressure gauge can visually read correctly while the boiler's internal circuit uses a different measurement point.
Check the manual for the exact fault code and verify if it corresponds to pressure before assuming that the pressure gauge is the culprit.
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.
