How to check if ref. 65116585 06 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 65116585 06. 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 65116585 06 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 off, with no lights or display when connected to the power supply.
Cause: The PCB controls the power supply to the entire boiler; if it is damaged, no current reaches any component.
Check the fuse and the power supply of the boiler before considering replacing the PCB.
- 02
An error code appears on the screen that does not disappear even after resetting.
Cause: The electronics block the boiler when detecting a problem and cannot resolve it on its own.
Note the code and cut the power for one minute; if the fault reappears, the PCB is the one that is failing.
- 03
In the WiFi versions, the boiler does not connect to the app nor can it be paired with the mobile.
Cause: The WiFi module is located on the PCB and can fail even if the boiler is functioning properly.
Bring the router closer and reset the boiler before thinking that the WiFi module is broken.
- 04
The remote control or thermostat does not turn on the boiler even though it shows a temperature.
Cause: The PCB does not receive or process the power-on command from the remote control or the communication system.
Check the wiring of the control in the terminals of the PCB before replacing it.
Fault codes for Ariston that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 302 | Internal communication fault | The main PCB may stop communicating with the display or the modules due to an issue with the board itself, such as a failure in the transceiver or problems with the soldering. Check the voltages on the board, the cables, and the connectors. Test with another display to rule out that it is the problem. If it continues to fail, the board needs to be replaced. |
| 303 | Fault in the main PCB. | The self-diagnostic system has detected a fault in the PCB that prevents it from functioning properly. Check the power supplies and the ground connections of the PCB. If you don't find any external issues, the PCB will need to be replaced. |
| 305 | Fault in the main PCB. | An internal fault in the PCB causes it to lock for safety reasons. Check that 230 V and 5 V are reaching it, review the ground connections and the connectors. If everything is fine and the fault reappears, the PCB needs to be replaced. |
| 306 | Fault in the main PCB. | There is a recurring fault in the PCB, whether in the circuits, the relays, or the regulation. Check the power supplies and the communications on the board. If you do not find external issues and the fault persists after a reset, the board needs to be replaced. |
| 307 | Fault in the main PCB. | The self-diagnosis has detected an internal problem in the PCB. Check the voltages, the bus, and the inputs. If the sensors and the wiring are fine, the solution is to replace 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.
