Flow meter Baxi Roca Laura Plus 28 F Ref. 122280010
The flow meter detects the passage of water when a tap is opened and commands the ignition to produce domestic hot water. When it fails, no hot water comes out even when the tap is open, which can be frustrating. This model, with reference 122280010, is compatible with Baxi Roca boilers from the Laura range, including models such as Laura 20/20 F and Laura RSI 20/20, among others. It is recommended to replace it when these symptoms occur or if the fault code 06: Overtemperature clixon open is displayed.

How to check if ref. 122280010 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 122280010. 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 122280010 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
You request domestic hot water and the boiler does not respond: you don't hear it trying to ignite the burner.
Cause: The flow detector does not send the water flow signal, so the boiler does not activate the ignition.
Before changing the part, make sure that the water inlet shut-off valves are fully open; a partially closed valve can reduce the flow rate.
- 02
The burner takes several extra seconds to start each time you turn on the tap.
Cause: A partially obstructed flow detector requires more accumulated flow to send the ignition signal, causing the delay.
Disassemble the body and check for limescale or debris in the duct; this is common in installations with hard water.
- 03
The temperature of the domestic hot water rises and falls even if you don't touch the tap.
Cause: The internal mechanism can give unstable readings if it has play or dirt, which causes the boiler to modulate the flame incorrectly.
Check the O-rings and the head-to-body adjustment before purchasing a complete kit: a small leak can affect the reading.
- 04
The boiler indicates a lack of water or flow even though the tank and pressure are fine.
Cause: The PCB is based on the information from the flow sensor; if it does not transmit properly, the warning is activated even if the water arrives correctly.
Check the pressure on the boiler's manometer: if it is below 1 bar, many boilers indicate a water fault, and it is not the part.
Fault codes for Baxi Roca that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 06 | Overtemperature clixon open. | The flow switch/flow meter (flow detector) can remain activated and send a false DHW demand; the pump does not circulate and the water in the heat exchanger overheats, triggering the thermal cut-out. Verify by observing a permanent DHW demand without opening the tap and measuring the detector's signal (pulses/continuity) or replacing it for cross-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.
