Gas Valve Baxi Roca Laura Plus 28 28 F Ref. 122260450
If your boiler does not ignite, shows flame lockouts, or modulates improperly, you may need the Baxi Roca gas valve Laura Plus 28 28 F. This valve regulates and allows the flow of gas to the burner according to the instructions on the boiler's PCB. When it fails, you may notice symptoms such as fault code 09, which indicates a power failure in the gas solenoid valves, or code 27, which signals a poor connection of the modulating valve. It is compatible with the models Laura Plus 28, Laura Plus 28 F, and Laura Plus 28/28F, among others. It should be replaced when it shows faults in its operation.

How to check if the reference 122260450 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 122260450. 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 gas valve 122260450 resolves.
The gas valve regulates and modulates the gas flow to the burner. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The flame flickers and turns off and on by itself several times in a row.
Cause: An intermittent fault in the regulation coil causes the gas flow to fluctuate instead of remaining stable.
Check if the fault coincides with the simultaneous use of heating and domestic hot water before replacing the gas valve.
- 02
No matter how you set the temperature, the boiler always heats to the maximum or turns off.
Cause: The modulation mechanism of the gas valve is stuck and does not respond to the commands from the PCB.
Check if the flame size changes when adjusting the temperature setting; if it remains the same, the issue points to the gas valve.
- 03
It starts well but shuts off by itself after a few seconds with a lock fault code.
Cause: The valve does not maintain the minimum required flow rate, and the flame sensor stops detecting it, cutting off the gas for safety.
Clean the ionization electrode and check its wiring before replacing the gas valve; a dirty sensor causes the same fault.
Fault codes for Baxi Roca that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 09 | Power supply fault in gas solenoid valves. | The gas valve does not open because it is not receiving voltage or has open coils; the boiler locks out as it cannot supply gas. Check for voltage reaching the valve during the ignition attempt and measure the continuity/resistance of the coils and the condition of the connectors. |
| 27 | Modulating valve poorly connected or fault in the control board. | The gas valve modulator (coil/actuator) is poorly connected or damaged, and the PCB cannot control it. Check the modulator connector and wiring on the valve, and verify the coil resistance and control signal from the PCB. |
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.
