PCB Baxi Roca R20/20F - Ref. 122122200
If your boiler does not start, locks out, or exhibits erratic behavior, you may need the Baxi Roca R20/20F PCB - Ref. 122122200. This board is responsible for controlling the ignition, burner modulation, pump, and safety features of the boiler. When it fails, you will notice that the boiler does not respond properly to commands. It is compatible with several models in the R series, such as the R 20/20 F, R 20 F, and R 30/30 F, among others.

How to check if ref. 122122200 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 122122200. 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 PCB 122122200 resolves.
The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler shows no signs of life, neither indicators nor display.
Cause: The power supply stage of the PCB, or its internal fuse, has stopped delivering current to the control electronics.
Check with a multimeter that mains power is reaching the input of the PCB before declaring it faulty.
- 02
Lockouts appear with codes that do not match any real fault in the pressure switch, NTC, or flame.
Cause: The PCB mismanages those signals and causes lockouts due to incorrect readings, not because of a fault in the sensors themselves.
Note the exact code and check those sensors for continuity with a multimeter beforehand.
- 03
The boiler turns on, runs for a few minutes, and then shuts off repeatedly on its own.
Cause: An intermittent fault in the PCB, such as a component that heats up and loses contact, causes it to shut down for safety without a real reason.
Check if the shutdown always occurs after the boiler has been running for a while and verify that the connectors on the PCB are properly seated.
- 04
The thermostat is unable to start the boiler.
Cause: The PCB is the one that receives and processes that command; if its signal input fails, the boiler will not respond even if the thermostat is working properly.
First, check that the thermostat is powered and that the wiring is correctly connected to the terminals of 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.
