How to check if the reference 147057273 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 147057273. 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 147057273 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 control panel does not turn on, no icon appears.
Cause: The remote control needs to receive power to operate; if there is no signal from the boiler, it remains off.
Check that the boiler has power and that the wiring to the control is properly connected before replacing the part.
- 02
The +/- buttons do not change the temperature or respond to touch.
Cause: The push buttons are on the same PCB as the display; if there is a fault in their contacts, nothing can be adjusted.
Test each button separately and check if the boiler modulates even if the control does not respond.
- 03
The pressure ('bar'), temperature icons, and power steps are not displayed.
Cause: These icons depend on the same display circuit; if it fails, they all disappear even if the boiler is functioning.
Check if the boiler heats and maintains pressure normally even though nothing is visible on the control panel.
- 04
The hot water tap icon does not respond when pressed.
Cause: This button activates the DHW mode from the remote control; if its contact fails, hot water cannot be activated from there.
Check if hot water continues to flow when opening a tap in the house, to rule out that the fault is in another point and not in the control.
Fault codes Baxi that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 20 | Communication error between control board and boiler control (>4 minutes). | The Control Board (147057273) may lose/block communication with the CCE base; check connectors/wiring and perform the control test (detach control, press 'service', reinsert until 'tc' appears). If it does not reset or the issue persists, replace the control or the board. |
| 22 | Inconsistent or illegible parameters on the boiler control board. | The Control Board has corrupted/unreadable limit values; to verify, restore factory settings (keys 'radiator' + 'bar') and check if it returns to '00'. If it persists, replace the control board. |
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.
