Filling Key for Ciao 24 CSI Boiler Ref. R2265
The filling key for the Ciao 24 CSI boiler allows water to be replenished in the heating circuit to maintain the proper pressure. When it fails, it can result in the inability to refill the circuit or a continuous loss of water, leading to an unwanted increase in pressure. This part is compatible with several Beretta models, such as Ciao 24 CAI, Option 24 CAI, and Kompakt 22 CAI, among others. It is advisable to replace it when you notice issues with filling the circuit or water leaks.

How to check if ref. R2265 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 R2265. 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 filling valve R2265 resolves.
The filling valve allows water to refill the heating circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The pressure in the circuit gradually decreases, and it needs to be refilled every few days.
Cause: The filling valve does not close completely and allows water to slowly pass into the system.
Close the valve tightly and monitor the pressure gauge for a couple of hours to see if the pressure continues to drop on its own.
- 02
Water is leaking right below the body of the tap.
Cause: The gasket or the internal seat is worn out and no longer seals when the valve is closed.
Dry the area and check if the drop reappears with the valve closed or only appears when refilling.
- 03
The circuit cannot be filled, or very little water comes out when opened.
Cause: The internal passage of the valve is blocked by lime or dirt from the network.
Check the water supply pressure and ensure that the inlet filter, if present, is clean before replacing it.
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.
