When you turn on the hot water tap or activate the heating, the Water Return Body Fagor FE 24 NOX (Ref. AS0003128) is responsible for directing and distributing the water between the boiler circuits. If this part fails, you may notice leaks, loss of pressure, or issues with hot water production. It is compatible with the Fagor FE 24 NOX and FE 24 NOX 1N models, among others. It is recommended to replace it upon detecting any of these symptoms to prevent further damage to the system.

How to check if the reference AS0003128 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 AS0003128. 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 hydraulic group AS0003128 resolves.
The hydraulic group includes the valve, the by-pass, and the water connections. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
There is moisture or constant dripping around the water/return block, even though the connections are tightly secured.
Cause: The body cracks due to heat or impact, and water leaks from the casing itself, not from a joint.
Dry the area well, pressurize the circuit, and locate the exact point: if the water is coming out of the plastic and not from a threaded joint, it is the body.
- 02
The boiler gradually loses pressure even though no water is visible anywhere.
Cause: A fine crack in the return body may leak only when the boiler is running and under high pressure, and evaporate before being noticed.
Check the pressure gauge when cold and again after a heating cycle; if it only drops with the boiler hot, suspect a small crack in the body.
- 03
There is a drip appearing right where the sensor or the bleed valve screws onto the return body.
Cause: The molded threads in the plastic wear out or crack over time due to the tightening of those components.
Loosen, clean, and reapply Teflon or a new gasket on that specific thread before considering the entire part lost.
- 04
The body has visible cracks or whitish and brittle areas in the plastic.
Cause: The plastic degrades with the continuous heat from the circuit and loses flexibility, especially near the fastening flanges.
With the boiler cold, inspect the entire body by pressing lightly with your finger: many cracks are not visible until there is pressure.
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.
