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)
13Main PCB fault.The main PCB is faulty or has defective internal/external connections; check the fuse and voltages of the PCB (230/5 V supplies) and connectors. If the issue persists with correct wiring and peripherals, replace the PCB.
11No reception from the main PCB (MMI line).Communication fault towards the PCB (receiver/MMI input of the PCB) or the cable between interface and PCB; check continuity of the MMI lead and 5 V on the interface. If the fault persists with a good cable/panel, the PCB is the cause.
How do I confirm that this PCB is the correct one for my boiler?
Check the silkscreened reference 0020076179 on your PCB and ensure that your boiler model is on the list of compatible ones; also compare the number and position of the connectors.
Which models is this PCB suitable for?
It is a PCB shared by several models of the same range (see Compatibility tab). If your model does not appear, send us a photo of the silkscreen and we will confirm it.
When installing it, do you need to parameterize or configure anything?
If you replace it with the same reference, it is usually sufficient to replicate the jumpers/configuration of the original; after installation, a technician should verify service parameters (type of gas, power settings) and check combustion and safety features.
Is it the same as the display or control panel?
No. This is the main PCB (controls ignition, modulation, sensor readings, and safety features). The display/user interface is a separate piece; if your fault is with the panel, it is not this PCB.
Why does a PCB fault occur and how can I prevent the new one from failing?
It is usually due to external causes: voltage spikes, shorts in the pump, fan, or valves, humidity, or poor grounding. Before installing the new one, check peripherals, wiring, and connectors, fix water leaks, and verify polarity and grounding.
What does refurbished mean and what coverage does it have?
Part removed from an out-of-service boiler, inspected and bench-tested; not factory new. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
