Ariston Clas Premium 24 Display PCB Cod. 460140000402
When you turn on the hot water tap, the Ariston Clas Premium 24 PCB Display (Cod. 460140000402) is responsible for controlling the ignition and operation of the boiler. This part regulates the modulation of the burner and the pump, ensuring that everything works correctly. If it fails, you will notice that the boiler does not start, gets locked, or exhibits erratic behavior, potentially showing faults such as 3 03 or 3 05. It is compatible with models from the Clas Premium range, such as the Clas Premium 24 and Clas Premium 30, among others. It is recommended to replace it upon detecting these issues to restore normal operation.

How to check if ref. 65109138 03 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 65109138 03. 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 65109138 03 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's display is off, but the boiler seems to be working because the pump or burner can be heard.
Cause: The display PCB only controls the screen and the visible controls, not the control unit that ignites the boiler.
Check if the boiler heats the water even if you don't see anything on the screen: if it heats properly, the fault is in the display.
- 02
The buttons on the panel do not respond to touch, although the screen is on.
Cause: The display module combines the screen and the buttons; a fault in its electronics can leave the screen lit but unresponsive to button presses.
Clean the surface of the buttons and press more firmly: in some models, wear on the touch membrane can appear as a fault of the PCB.
- 03
The fault codes cannot be checked because the display does not show them, even though the boiler is locking up.
Cause: If the display module fails, the control unit can continue generating fault codes, but they cannot be read on the screen.
Check if the boiler has any pilot light or indicator that shows a blockage, to confirm that the fault is only a display issue.
Fault codes for Ariston that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 3 03 | Main PCB fault | Self-diagnosis detects an internal fault in the PCB (e.g., micro/EEPROM or internal power supply). Check the board voltages (5/12/24 Vdc), perform a visual inspection, and rule out wiring/display before replacing the board. |
| 3 05 | Main PCB fault | Main PCB fault detected by the internal electronics. Check mains supply to the board, secondary voltages, and ensure there are no shorts/damage to components before replacing it. |
| 3 06 | Main PCB fault | The internal electronic self-test detects a malfunction of the PCB. Check power supply lines/low voltages, connectors, and absence of thermal damage; if the issue persists, replace the PCB. |
| 3 07 | Main PCB fault | The boiler identifies an internal fault in the PCB. Confirm that the rest of the peripherals/communications are correct and measure voltages/regulators on the PCB; if the error persists, replace the 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.
