How to check if the reference 61302539 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 61302539. If it is not visible, do not identify the part by 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 61302539 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 butterfly valve has broken, and I cannot open or close the valve.
Cause: The plastic of the remote control breaks over time due to use and cracks at the base where it fits into the stem.
Check if the metal stem is still intact under the broken control; if so, sometimes the problem is just the control and not the entire valve.
- 02
The valve does not close completely and water keeps flowing into the circuit.
Cause: The internal seat of the stem is worn or has scale and does not seal properly when turning the knob.
Close it completely and check if there is still a water leak; if the control turns loosely and without a clear stop, the wear is confirmed.
- 03
The pressure does not rise even though the valve has been open for a while.
Cause: The passage is blocked by dirt or limescale accumulated in the narrow duct of this type of valve.
Check that the mains pressure reaches the valve before declaring it blocked.
- 04
The butterfly valve turns, but I don't notice it opening or closing the passage.
Cause: The internal shaft has become decoupled from the control even though it continues to rotate without effect.
Check if the control knob turns freely without any stops or resistance; this free rotation indicates that the shaft is broken internally.
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.
