Ariston Cares S 24/30 PCB Ref. 65118213
The Ariston Cares S 24/30 PCB, with reference 65118213, is a component that controls the ignition, burner modulation, pump, and safety features of the boiler. If it malfunctions, the boiler may fail to start, lock out, or behave erratically, which can lead to frustration. This part is compatible with models such as Cares Premium 24 EU2, Cares S 24, and Inoa 24 S, among others. It should be replaced when errors such as 3 03, 3 05, 3 06, or 3 07 are detected.

How to check if ref. 65118213 04 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 65118213 04. 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 65118213 04 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 indicator lights on.
Cause: If the power supply to the PCB fails, no current reaches any control element.
Check the fuse on the PCB with a multimeter before replacing the entire board.
- 02
The fan turns on and the cycle starts, but the flame never ignites.
Cause: The PCB sends the ignition command to the gas valve and the electrode; if it fails, the sequence is interrupted before ignition.
Check that the ignition electrode produces a visible spark before assuming the problem is the PCB.
- 03
The pump or the three-way valve do not activate even though the boiler seems to be working normally.
Cause: The relays on the PCB activate these components; if one gets stuck or burned out, the element stops receiving the command.
Listen for the relay click when requesting heating; if you don't hear it, focus on the PCB rather than the component.
- 04
The boiler control does not respond to any button, as if it were locked.
Cause: A hang of the microcontroller on the PCB leaves the interface unresponsive even though there is power.
Disconnect the boiler from the power supply for a couple of minutes and try again before replacing the PCB.
Fault codes for Ariston that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 3 03 | Main PCB fault. | Internal fault of the PCB (control/management or power supply) preventing correct start-up; check 230 V~ input and regulated voltages (5/12 V) on the board, connections, and that the error persists with peripherals disconnected. |
| 3 05 | Main PCB fault. | PCB anomaly (components/firmware/power supply) that locks the electronics; check 230 V~, stabilised outputs, relays, and bus with the display; if after reset and disconnection of peripherals the fault persists, the PCB is damaged. |
| 3 06 | Main PCB fault. | Fault in the PCB (CPU/regulators/soldering) causing internal error; confirm by measuring voltages on the PCB, inspecting for damage/overheating, and isolating external wiring to rule out external causes. |
| 3 07 | Main PCB fault. | Critical fault in the PCB that disrupts control logic; check power supply and outputs of the board, continuity of connectors, and that the fault code appears even without sensors/actuators connected to confirm replacement. |
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.
