How to check if ref. 65109138 03 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- 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 that require diagnosis on the PCB 65109138 03
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.
Ariston fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 3 03 | Main PCB fault | This code requires technical diagnosis according to the model manual and its review. It does not confirm on its own that this part is faulty nor justifies its replacement. The causes and the exact reference must be verified before intervening. |
| 3 05 | Main PCB fault | This code requires technical diagnosis according to the model manual and its review. It does not confirm on its own that this part is faulty nor justifies its replacement. The causes and the exact reference must be verified before intervening. |
| 3 06 | Main PCB fault | This code requires technical diagnosis according to the model manual and its review. It does not confirm on its own that this part is faulty nor justifies its replacement. The causes and the exact reference must be verified before intervening. |
| 3 07 | Main PCB fault | This code requires technical diagnosis according to the model manual and its review. It does not confirm on its own that this part is faulty nor justifies its replacement. The causes and the exact reference must be verified before intervening. |
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.
