CEME PB 6412/VAR Pressure Switch For Baxi Roca Neobit 24/24F Boiler - Ref. 125995169
Pressure switch manufactured by CEME S.p.A. (Carugate, Italy), manufacturer code PB 6412/VAR, installed in Baxi Roca boilers from the Neobit, Novamax, Novanox, Platinum, Victoria Plus, Bios, and Altais series. It operates within a pressure range of 0.2 to 2 bar, with a maximum of 4.5 bar, and interrupts the contact if the pressure is incorrect. The replacement requires first confirming the fault of the component through technical diagnosis, even when the boiler is locked due to a pressure fault.

How to check if ref. 125995169 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 125995169. 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.
What to check before replacing the water pressure switch 125995169?
Common symptoms and faults
- 01
The boiler locks out with a pressure fault even though it is properly bled and has normal pressure.
Cause: The pressure switch is not closing properly, so the PCB thinks there is no pressure even though there is.
Check the actual pressure on the boiler's manometer and bleed if necessary, before declaring the pressure switch faulty.
- 02
The burner does not ignite; it remains waiting even though the pump or the fan can be heard operating.
Cause: Without the pressure switch's closed contact, the control board does not give the final ignition command for safety reasons.
If the actual pressure is correct, ask the technician to check the connections and the switching of the hydraulic pressure switch.
- 03
The boiler turns on and off several times in a row, as if it is losing contact.
Cause: A worn or dirty contact inside the pressure switch can open and close intermittently without relation to the actual pressure.
Do not manipulate the pressure switch with the boiler running. Note the fault code and request a check of the connector and the pressure switch.
- 04
The pressure fault appears and disappears on its own, without any intervention on the circuit.
Cause: An intermittent switching or connection can cause the electronics to interpret a pressure fault even if the pressure gauge does not change.
Keep a record of when the fault occurs (time, if the pump has just started, etc.) to confirm the pattern before replacing it.
Fault codes Baxi Roca that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| E10 | The hydraulic pressure switch does not authorize operation (low water pressure). | If the water pressure switch/sensor is faulty (open contacts, erratic reading, or defective wiring), the boiler interprets it as a lack of pressure and locks with E10; check that the pressure gauge reads ~1–1.5 bar and verify the continuity/signal of the pressure switch at the PCB connector. |
| 60 | Lack of water in the heating circuit (insufficient pressure) – indicated by LED 60 on Neobit S. | A water pressure switch/sensor that does not switch or gives an out-of-range signal causes the electronics to detect a lack of pressure and illuminate LED 60; confirm actual pressure on the pressure gauge and measure continuity/signal of the hydraulic pressure switch. |
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.
