PCB Renova Teknic F23E Ref. 0020025308
Renova Teknic presents the PCB F23E, reference 0020025308. This control board is responsible for managing the ignition, burner modulation, pump, and safety features of the boiler. If it malfunctions, you may notice that the boiler does not start, locks out, or operates erratically. It is compatible with models such as Renova Teknic F23E and Renova Teknic C23E, among others. A technician must confirm through diagnosis whether it needs to be replaced when you experience these symptoms or in the event of a communication fault reflected in fault codes F11, F13, or F20.

How to check if ref. 0020025308 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 0020025308. 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 0020025308
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 shows no signs of life, no lights or display.
Cause: The PCB distributes power to the entire appliance; if it's damaged, nothing receives power.
First, check the fuse on the PCB and ensure that the power plug is working.
- 02
The burner ignites, makes a combustion noise, and then shuts off immediately.
Cause: A fault in the control electronics can interrupt the signal that keeps the gas open.
Check the pressure switch and the flame sensor first, as they often cause the same fault.
- 03
The clock or the boiler settings are erased every time the power goes out.
Cause: The battery or the capacitor on the PCB that maintains the memory may have been depleted.
Check if the PCB has a separately replaceable backup battery.
- 04
The domestic hot water is not heating sufficiently, even though the gas and the burner are working.
Cause: The modulation electronics may not be properly regulating the burner's power.
Check the temperature set on the panel and the water flow.
Renova fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| F13 | Main printed circuit board fault. | The main PCB (0020025308) is defective or not communicating with the rest of the equipment (fault in tracks/connectors/memory), causing immediate lockout. Check 230 V/5 V power supplies, inspect harness and solder joints; if the issue persists, test/replace the board. |
| F20 | Communication error between the user interface and the main PCB (software incompatibility). | The installed interface is not compatible or the PCB 0020025308 does not recognise/parameterise the interface (DSN/product code/software); communication fails and the boiler locks out. Check product code and parameterisation, UI↔PCB connections and, if necessary, update/replace the board or display. |
| F11 | Interface-main circuit communication fault. | The PCB 0020025308 may fail in the communication channel with the interface (damaged driver/connector) and the boiler shows a loss of signal. Check the flat cable and 5 V on the interface; reseat/reconnect and, if it persists, test with another PCB or interface to isolate the fault. |
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.
