How to check if the ref. 20042403 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 20042403. 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 20042403 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 cannot fill the heating circuit.
Cause: The internal passage of the valve is blocked by scale or the mechanism does not open completely.
Check that the main network valve supplying the filling is open before changing the filling valve.
- 02
It is leaking from the threaded mouth of the valve.
Cause: The connection thread is not properly tightened or the flat gasket of that fitting is damaged.
Disassemble the connection and check (or replace) the gasket of the threaded mouth before considering the entire valve faulty.
- 03
It leaks water when the filling valve is activated.
Cause: The internal shutter does not close properly and allows water to flow continuously.
Turn off the valve completely and check with a dry cloth if it is still dripping after a few minutes.
- 04
The handle turns loosely without indicating that it is closing.
Cause: The internal stem has become uncoupled from the closing mechanism and the handle turns freely.
Turn the handle slowly and notice if at any point it offers real resistance to closing; if it turns freely throughout the entire range, the stem is broken.
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.
