PCB Baxi Roca Victoria 20 20 CF Ref. 122126410
The Roca Baxi Victoria 20 20 CF boilers use the Roca Baxi Victoria 20 20 CF PCB, which is responsible for controlling essential functions such as ignition, burner modulation, and the pump, as well as the safety features of the boiler. When this part experiences faults, the boiler may fail to start, lock out, or operate erratically, which can result in errors such as 50-70-90 and 40-60-90. This PCB is compatible with several models in the Victoria range, including the Victoria 20/20, Victoria 20/20 CF, and others. It is advisable to replace it if these symptoms or errors are detected.

How to check if ref. 122126410 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 122126410. 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 122126410 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 does not turn on and there are no lights on the control panel.
Cause: The PCB is not receiving power, sometimes due to a blown fuse F1.
Measure the continuity of the F1 fuse of 3.15A on the PCB before purchasing it complete.
- 02
The room thermostat is not able to start the boiler.
Cause: The PCB does not receive or interpret the demand signal from the thermostat.
Check that the thermostat makes contact by bridging its terminals on the PCB before considering it faulty.
- 03
The boiler ignites the burner but shuts off immediately without any apparent reason.
Cause: The PCB interrupts the cycle because it does not correctly validate a safety signal during startup.
First, rule out the pressure switch and the flow sensor, as they are the most common causes of this shutdown before checking the PCB.
- 04
It has completely stopped responding, without any prior warning signs.
Cause: A sudden fault in a component interrupts the control circuit.
Visually inspect the PCB for any swollen or burnt components before replacing it.
Fault codes for Baxi Roca that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 50-70-90 | Safety relay does not close after demand. | The PCB (control board) may fail in the safety circuit/relay (contacts stuck or relay not switching). Check by listening/measuring the relay operation on the board and continuity/soldering; if the safety inputs are OK and the relay does not switch, replace the PCB. |
| 40-60-90 | Fault in the safety circuit (boiler reset). | Safety circuit fault managed by the PCB (fuse/relay/reset circuit on PCB). Check input voltages to the PCB, fuse F1/F2, and outputs to safeties; if external signals are correct and the boiler does not reset, the cause is 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.
