Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
F5Control board fault: internal fault in the electronic circuit that locks the boiler.It is the code that points directly to THIS part (the main PCB MU0870700): it is triggered when the electronics/software protections of the board detect an internal fault. Verify by replacing or checking the control board after ruling out power supply; if it persists after a reset (switch to O and back to position), the board is the cause.
F10Fault in the control or closure of the gas valve (the boiler locks and cannot be unlocked).The Fagor documentation explicitly states that it could be "a fault in the control circuit or the gas valve," so the MU0870700 PCB (control/modulation stage of the valve) is a documented cause, not just the valve. Verify by measuring the modulation signal delivered by the PCB to the valve; if the valve and its wiring are correct, the origin is the PCB.
How do I know if this PCB is for my boiler?
Verify the reference MU0870700 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part.
What is it used for?
The PCB controls the ignition, modulation, sensor readings, and safety features of the boiler.
Is the boiler not igniting, locking out, or is the control board unresponsive?
After ruling out mains voltage, fuse, and connectors, a damaged PCB causes lockouts, blackouts, or erratic display. Repair the external cause before installing the new one.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
After installation, a technician must adjust the service parameters (type of gas, power settings) and check combustion and safety features.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
