How to check if ref. 20035649 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.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference 20035649. If it is not visible, do not identify the part from its shape alone.
2. Check the full boiler model on its data plate and look for it in the model associations on this page.
3. Compare the connections and physical body with the original part before installation.
4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

Symptoms and faults that the filling valve 20035649 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 open the valve to refill the pressure and the manometer does not rise, or rises very slowly.

  Cause: The internal cartridge is blocked or the opening mechanism does not allow enough water to pass through.

  Make sure that the main water valve is open and that there is no limescale blocking the inlet before changing the cartridge.

• 02

  Water is leaking from the cartridge body even when the tap is closed.

  Cause: The internal seals of the cartridge are worn out and no longer seal properly.

  Dry the area well and observe for a few minutes with the boiler cold to confirm that the dripping comes from the cartridge and not from a nearby connection.

• 03

  After recharging, the pressure does not hold: it needs to be refilled every few days.

  Cause: The cartridge does not seal tightly in its resting position and allows water to pass through slowly.

  Check for moisture or limescale stains right in the area of the cartridge, indicating that the leak is there and not at another point in the circuit.

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.
