How to check if the reference 122123660 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 122123660. 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 122123660 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 is completely dead, no indicators or display.
Cause: If the Atmel microcontroller on this PCB fails, the boiler will not operate.
Check if there is mains voltage to the boiler before declaring the PCB faulty.
- 02
The boiler shuts down suddenly as soon as it is turned on, as if it loses power abruptly.
Cause: A blown fuse on the PCB cuts off the power, even if the rest of the boiler is functioning properly.
Before changing the PCB, measure with the multimeter if the fuse F1 is blown: it is a cheap and common fault.
- 03
A fault code is triggered without any mechanical cause to explain it.
Cause: A microcontroller fault can cause false safety lockouts by misinterpreting the signals from the sensors.
Note the exact code and first rule out the sensor or the component it points to before replacing the PCB.
- 04
The boiler does not respond to the thermostat or the panel, even though the display remains on.
Cause: If the microcontroller on the PCB fails, it will not process commands even if the screen is lit.
Check if any physical button on the panel responds; if none work, the problem is not with the thermostat.
Fault codes for Baxi Roca that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 40-70-90 | Power failure in gas solenoid valves (safety relay fault). | The safety relay integrated into the PCB becomes excited/stuck or its contacts fail, improperly maintaining or cutting off the power supply to the gas valves. Verify by measuring voltage at the PCB output towards the gas valves and check the operation/status of the relay on the PCB. |
| 50-70-90 | Fault in the safety relay (does not close after demand). | Fault in the safety relay of the PCB (contacts not closing or damaged coil) prevents authorisation of ignition after demand. Check continuity/operation of the relay on the PCB and ensure that the board output switches correctly under demand. |
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.
