How to check if ref. 8716148072 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 8716148072. 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 8716148072 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
You need to recharge the pressure more frequently than usual.
Cause: The lever does not close properly and causes a constant internal leak.
Measure the pressure before and after a day without using the boiler to verify that the loss is continuous, not occasional.
- 02
Water comes out from the lever or from the base when it is closed.
Cause: The gasket of the mechanism has worn out with use.
Dry the area and observe for a few hours to ensure that the dripping is coming from the faucet and not from a nearby pipe.
- 03
The lever is stuck or difficult to move to recharge pressure.
Cause: The limescale deposits from the mains water block the internal mechanism over time.
Move the lever carefully in small increments; if it doesn't move, do not force it, as it could break before confirming that this is the fault.
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.
