Flow switch Fagor FE 25 NOx 1 N Ref. MUR000082
The flow switch Fagor FE 25 NOX 1 N, with reference MUR000082, is a flow detector that is responsible for detecting the flow of water when a tap is opened, thus activating the burner to heat the domestic hot water. If this component fails, you will notice that no hot water comes out even when the tap is open, as the boiler does not detect the demand for hot water. This flow switch is compatible with the boiler Fagor FE 25 NOX/1 N, among others. It is recommended to replace it when these symptoms occur to ensure the proper functioning of the hot water system.

How to check if ref. MUR000082 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 MUR000082. 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 flow meter MUR000082 resolves.
The flow meter detects the passage of water to activate the domestic hot water. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
When I turn on the hot water tap, nothing happens; the boiler doesn't ignite the burner.
Cause: The flow detector does not detect the passage of water and does not send the start command to the control board.
Open the tap fully and wait a few seconds: a very low flow rate may not be sufficient to activate the detector.
- 02
The hot water intermittently cuts off while using the shower or the tap.
Cause: The detector intermittently loses signal due to dirt or a worn internal contact.
Check if the cut coincides with the opening of another tap at the same time, which reduces the flow throughout the entire system.
- 03
The boiler turns on for heating but does not respond when domestic hot water is requested.
Cause: It's a typical pattern of a domestic hot water flow detector that has stopped working while the rest of the circuit is functioning properly.
Check the cold water inlet filter, as if it is dirty, it reduces the flow below the minimum required.
- 04
The flow of hot water is weaker than before, even though the overall pressure in the house is normal.
Cause: The internal moving part of the detector does not move enough to activate the contact with low flow rates.
Check the pressure on the boiler's manometer before intervening: if it is low, first check the filling valve and the expansion vessel.
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.
