Water Pressure Switch Fagor FE 25 NOx CEME Ref. MUR000041
Water pressure switch manufactured by CEME (type PC), installed in Fagor FE 25 NOX boilers. It monitors the water circuit pressure and cuts off the flow if it detects an anomaly, preventing the boiler from operating under incorrect pressure. The replacement requires first confirming the fault of the component through technical diagnosis, even when pressure variations are no longer read correctly or the electrical contact fails.

How to check if ref. MUR000041 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference MUR000041. 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 that require diagnosis in the pressure switch MUR000041
The pressure switch controls the air or water pressure to authorize operation. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler locks out when trying to ignite due to low water pressure.
Cause: The water pressure switch prevents the operation of the burner if it detects an incorrect pressure, whether real or due to a fault in the component itself.
Check the filling pressure on the boiler's manometer: if it is normal and it continues to block, the problem may be the pressure switch.
- 02
The display shows a pressure fault code that is always the same.
Cause: A contact that does not close properly or gets stuck constantly sends an incorrect pressure reading to the PCB.
Do not force, hit, or bridge the component. Request a technical check according to the equipment manual before deciding on its replacement.
- 03
The boiler starts and stops intermittently without any apparent reason.
Cause: If the pressure switch changes state irregularly, the control board interprets pressure changes that are not real.
First, rule out a leak in the circuit or in the expansion vessel, as they can cause the same starting and stopping issue.
- 04
The pressure switch does not click or feels stuck when manually changing the pressure.
Cause: The internal mechanism can get stuck over time and may not switch even if the pressure changes.
With the boiler depressurized, check if the pressure switch stem moves freely before replacing it.
Fagor fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| H20 | Water pressure switch intervention (pressure/lack of water in the circuit). | The water pressure switch opens its contact when the primary pressure falls below the threshold and the PCB displays H20; verify by reading <1 bar on the pressure gauge and checking continuity of the pressure switch micro by varying the pressure or bridging it only for testing. |
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.
