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)
E04Lockout due to contact resistance / damaged PCB hardwareThe modulation PCB detects an anomaly in the power supply to the gas valve; if the wiring and valve are correct, the hardware of the board is damaged. Check the connection to the valve and, if it persists after a reset, replace the PCB.
E15Wiring configuration errorThe PCB recognises the type of boiler by jumpers/wiring (e.g., bridge 6–7 on X7); if the configuration and continuity (X7/X9) are correct and the error persists, the fault is with the PCB. Check bridges/continuity and replace the PCB if necessary.
E31Pérdida de comunicación del mando a distanciaBUS transceiver fault on the PCB prevents communication with CAR/CARV2 despite correct wiring. Check polarity and dedicated line (terminals P.C.B. 42–43/40–41) and, if the control board is fine, replace the PCB.
E37Baja tensión de alimentaciónIf the mains (230 V ±10%) and external fuses/wiring are correct and the error persists, the internal power supply of the PCB is defective. Measure >190 VAC at the input; if correct and E37 remains, replace the PCB.
E01Lockout due to ignition failureAfter checking the spark, voltages to the igniter/gas valve, and electrodes/gas are correct, the electronic module does not control the ignition. Follow the measurements on the indicated connectors and, if necessary, replace the PCB.
E20Lockout due to parasitic flameWith the detection electrode and wiring in good condition, the detection circuitry on the PCB interprets the flame as non-existent. Confirm electrode/ground; if the issue persists, replace the PCB.
How do I know if this PCB is for my boiler?
Verify the reference 018068 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a B&P 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.
