How to check if the reference 61312368 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 61312368. 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 61312368 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 boiler is gradually losing pressure, although no leaks are visible in the radiators or pipes.
Cause: The filling valve does not close properly and allows water to flow very slowly into the network circuit.
Dry the area around the valve thoroughly, close it completely, and check in a few hours if there is any moisture at the outlet fitting.
- 02
Water is dripping right at the tap, even when it is closed.
Cause: The gasket or the internal seat of the valve is worn out and no longer seals.
First, tighten the connection fitting in case the leak is coming from there and not from the valve itself.
- 03
It is very difficult to turn it, or it simply does not move.
Cause: It has seized up due to accumulated scale inside after years of not being handled.
Try to move it gently, without forcing the lever, before considering the part to be stuck.
- 04
When opening it to recharge pressure, no water enters or very little water enters.
Cause: The internal passage of the valve is blocked by limescale.
Check that the main supply valve is open and that there is water pressure before discarding 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.
