Main Control PCB Ecoflam Linda 28 60 CS CPA Ref. 952935
The Ecoflam Linda 28 60 CS CPA Main Control PCB Ref. 952935 manages the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler does not start, locks out, or exhibits erratic behavior. This board is compatible with models such as Linda+ 28/60 CS CPA, among others from the Ecoflam Linda+ CS CPA and CS CPR ranges, as well as equivalent boards from Ariston. A technician must confirm through diagnosis whether it needs to be replaced upon noticing any of these symptoms or if errors such as 21 or 25 occur.

How to check if the ref. 952935 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 952935. 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 952935
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 unresponsive: the display does not turn on, the fan does not start, it does nothing.
Cause: The PCBs are not distributing power to the rest of the system.
Before replacing them, check the fuse of each PCB and ensure that the connector between the two PCBs is properly fitted.
- 02
A fault code appears on the display that reoccurs immediately after resetting.
Cause: The control detects an internal fault that cannot be resolved with a simple reset.
Note the code and compare it with the fault table before replacing the complete assembly.
- 03
The boiler stops by itself in the middle of a heating cycle, without prior warning.
Cause: An intermittent fault in the control causes micro-cuts that reset the PCB.
Check that the connectors between the two PCBs and the harness wires are not loose or corroded before replacing the assembly.
- 04
The screen remains off or displays stripes and symbols that do not mean anything.
Cause: The circuit that powers or controls the display is damaged on one of the two PCBs.
Disconnect and reconnect the flat cable of the display: a poor connection gives the same symptom as a faulty PCB.
Ecoflam fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| Error 21 | Internal equipment/PCB fault. | The main PCB is faulty or has defective power/regulation; check 230 V and 5/12 V, fuses, and shorts on the board. If the issue persists after checking wiring and grounds, replace the PCB ref. 952935. |
| Error 25 | CRC connection error (communication fault in the internal bus). | The main PCB does not correctly validate the CRC frames with the interface/modules board; check the bus/wiring, grounds, and connectors. If the CRC fault persists, the main PCB is likely defective. |
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.
