PCB for Boiler DESY 24 CA CPR - Ref. 65101374
The Ecoflam Desy boilers, such as the Desy 24 CA CPR, use this PCB to control functions such as ignition, burner modulation, and system safety features. When the PCB fails, you may notice that the boiler does not start, locks out, or exhibits erratic behavior. Fault codes such as 301, 303, 305, 306, or 307 may also appear, related to internal issues with the electronic part. This part is compatible with models from the Ecoflam Desy 24 range, as well as some Ariston boilers. It is advisable to replace it when it shows faults to avoid larger problems.

How to check if ref. 65101374 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 65101374. 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 65101374 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 does not ignite at all, and the pilot light does not illuminate.
Cause: The electronic control is not receiving power or has a damaged component.
Check the fuse on the PCB and verify that there is voltage at the terminal block before replacing it.
- 02
An error code appears on the screen and the boiler locks out.
Cause: The PCB detects a sensor signal out of range and shuts off the ignition for safety.
Note the fault code, reset the boiler, and observe if the fault reappears quickly or takes time to show up.
- 03
The thermostat in the house is unable to start the boiler.
Cause: The PCB does not receive the heat demand due to a fault in the electronic control input.
Check the wiring and power supply of the thermostat before assuming that the fault is in the PCB.
- 04
The boiler ignites but turns off after a few minutes repeatedly.
Cause: An intermittent fault in the electronic control shuts down the cycle before it is completed.
Check if the shutdown coincides with the boiler being hot for a while, which indicates a thermal fault in the PCB.
Fault codes Ecoflam that this part solves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 301 | EEPROM error (internal electronic part). | The EEPROM memory of the main PCB is corrupted/damaged; check the 230 V power supply and 5/3.3 V voltages on the PCB and bus/display connections; if reprogramming is not possible or the fault persists, replace the PCB. |
| 303 | Main PCB fault (internal electronic part). | Self-diagnosis detects an internal fault in the main PCB; check the network/ground, connectors, and absence of shorts in the PCB; if everything is correct and the code repeats, the cause is the PCB and it must be replaced. |
| 305 | Main PCB fault (internal electronic part). | Main PCB fault with lockout; after checking power supply, wiring, and connectors, if there are no other causes (peripherals/bus), the board is responsible and must be replaced. |
| 306 | Main PCB fault (internal electronic part). | Internal fault recognized by the self-diagnosis on the PCB; confirm voltages and continuity of harnesses, and if there are no external anomalies, replace the PCB. |
| 307 | Main PCB fault (internal electronic part). | Internal fault of the main PCB; if the bus and peripherals are correct, the origin is the PCB itself and it should be replaced. |
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.
