Fagor FE 24 NOx Plate Heat Exchanger Ref. AS0003395
The Fagor FE 24 NOX Plate Heat Exchanger, with reference AS0003395, is a component that transfers heat from the primary circuit to the domestic hot water instantly. When it fails, the user will notice that the water comes out lukewarm or with fluctuating temperature, in addition to experiencing a decrease in the flow of hot water. This heat exchanger is compatible with boilers from the FE 24 NOX range, such as the models FE24NOX1N, FE24NOX1B, and FEE24NOX1N, as well as some models from the FE 24 TC and FE 26 TC ranges. It is recommended to replace it when these symptoms of lack of heat or inadequate flow occur.

How to check if the reference AS0003395 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 AS0003395. 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 heat exchanger AS0003395 resolves.
The plate heat exchanger transfers heat to the domestic hot water. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The domestic hot water starts hot and becomes lukewarm after the tap has been open for a while.
Cause: Limescale builds up between the plates and obstructs the flow of heat.
Check for scale in the inlet filter and measure the water hardness before replacing the part.
- 02
There is a water leak under the boiler that coincides with the times when hot water is requested.
Cause: The heat exchanger has lost tightness and is leaking water through the plates.
Differentiate if the leak is constant or only when opening the domestic hot water tap to rule out nearby joints and fittings.
- 03
The boiler tries to provide hot water but gets blocked or modulates in an unstable manner.
Cause: A reduced step due to incrustations decreases the flow below what the control unit considers safe.
Check the filter and the inlet flow meter before confirming the replacement of the heat exchanger.
- 04
There is a slight knocking or bubbling sound right when requesting hot water.
Cause: The narrowed passage due to scale causes turbulence inside the heat exchanger.
Bleed the circuit and check the pressure of the installation before attributing it to the heat exchanger.
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.
