Fagor Ecocompact FE-20E 1N Type FPL7201 PCB (control board)
The Fagor Ecocompact FE-20E 1N Type FPL7201 PCB is a component that controls the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the user may notice that the boiler does not start, locks out, or exhibits erratic behavior, indicating issues such as F5 or F8. This part is compatible with models from the Fagor Ecocompact FE 20E range, among others. It is recommended to replace it in case of faults in the boiler's operation or if the mentioned errors occur.

How to check if the reference FAG04000351 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 FAG04000351. 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 FAG04000351 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 start even though there is gas and water: the fan does not even spin.
Cause: The relay on the PCB is not switching to give the start command to the fan.
Measure with a multimeter if there is power at the fan connector when you request heating.
- 02
It ignites well but stops modulating and always operates at maximum power.
Cause: The modulation circuit of the PCB has lost control over the gas valve.
Make sure that the NTC sensor on the supply side is not giving an erratic reading, as it can simulate this fault.
- 03
The boiler loses the programmer's time or resets every few days.
Cause: There is a memory retention fault in the PCB.
First, check if there are repeated power supply cuts in the house before replacing the PCB.
- 04
It turns off halfway through a heating or domestic hot water cycle without displaying any fault code.
Cause: A specific fault in the microprocessor interrupts the cycle without locking or notifying of a fault.
Note the exact moment it turns off (start-up, operating, shutdown) to determine if the issue is with the PCB or another component.
Fault codes for Fagor that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F5 | PCB fault (internal fault of the electronic circuit). | The main PCB detects an internal anomaly or fault in its protections/software, which causes the boiler to lock out; verify by measuring the power supply voltages of the PCB (230 V input and 5/12 V secondary), inspecting relays and tracks/capacitors, and ruling out a reset by autotest. |
| F8 | Communication fault between the main circuit (PCB) and the control holder. | The communication between the main PCB and the control board fails (source, bus, or interface on the board); check the power supply to the control board from the PCB, continuity of the harness and signal/bus, and if there are 5 V/Tx-Rx on the board before replacing the control board or 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.
