Pressure Sensor Baxi Roca Victoria 24 24 F Ref. 125568703
The pressure sensor Baxi Roca Victoria 24 24 F is a sensor that measures the water pressure in the heating circuit and sends this information to the control board. If it fails, you may notice incorrect readings and lockouts due to low pressure, which can generate fault codes such as E10 or E164. This sensor is compatible with models from the Victoria range, as well as others like Neobit, Bios, Novanox, Novamax, and Neodens, among others. It is usually replaced when it shows measurement failures or causes problems in the operation of the boiler.

How to check if ref. 125568703 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 125568703. 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 125568703
The pressure sensor measures the water pressure for the electronics. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The display shows a pressure different from that of the installation's manometer.
Cause: The sensor sends an incorrect pressure signal to the PCB, and the control unit relies on that data.
Compare the reading on the screen with an external manometer placed at the same point in the circuit before considering that the part is defective.
- 02
The boiler locks out due to low pressure even though the circuit is full.
Cause: If the signal from the sensor decreases or becomes unstable, the control unit interprets that there is a lack of water and turns off the equipment for safety.
Bleed the air from the circuit and check that the actual pressure is between 1 and 1.5 bar before changing the sensor.
- 03
The pump does not modulate correctly, it always operates at maximum speed or does not respond to changes in demand.
Cause: In systems with a modulating pump, the electronics adjust the speed according to the signal from the sensor, and incorrect data affects that regulation.
Observe if the behavior of the pump changes when adjusting the actual pressure of the circuit with the filling valve.
- 04
The pressure warning or the fault code appears and disappears without a clear pattern.
Cause: A loose contact or wiring in the sensor causes an intermittent signal that the PCB interprets as a real anomaly.
Check the connector of the sensor and the wiring up to the PCB before replacing the part.
Fault codes Roca that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| E10 | The hydraulic pressure switch does not confirm operation (lack of pressure in the heating circuit). | If the pressure sensor/pressure switch (125568703) does not detect the correct pressure and does not close, the PCB does not enable the boiler and E10 appears; check the actual pressure on the manometer (≈0.7–1.5 bar when cold) and the switching/wiring of the pressure switch (>~0.5 bar). |
| E164 | Lack of switching/consensus of the hydraulic differential pressure switch. | In BIOS, the differential pressure sensor does not change state even though there is pressure/flow (damaged membrane/micro), so the electronics do not receive consensus; check pressure and continuity of the pressure switch during demand and replace if it does not switch with correct values. |
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.
