- 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 that require diagnosis in the filling valve 014735
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 cannot recover the pressure of the heating circuit when opening the valve.
Cause: The internal mechanism is blocked by limescale and does not allow water to pass through even when you open the control.
Make sure that the mains water valve supplying the boiler is open before touching the filling valve.
- 02
The faucet drips or leaks water even when it's closed.
Cause: The blue cap and its mechanism have lost their seal due to wear on the internal seat.
Tighten the control carefully until it reaches the closed position; if it continues to drip, the part is worn out.
- 03
The control is seized and does not turn to open or close the water flow.
Cause: The accumulated limescale on the spindle blocks the rotation after a long period of disuse.
Try gently tapping it before forcing it; if it doesn't give, don't keep insisting.
- 04
The boiler repeatedly loses pressure and needs to be refilled often.
Cause: The valve does not close completely and allows water to escape slowly but steadily.
Mark the cold pressure level and check it after a few hours; if it always drops from the same place, it's the valve.
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.
