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 printed circuit board fault.The main PCB (S1019000) does not pass the internal self-diagnosis; this is usually due to an electronics/EEPROM fault or the PCB not generating its internal voltages. Check the 230 V input, fuse, and low voltages (5/15/24 V) on the PCB; if these are correct and the wiring is OK, replace the PCB.
20Communication fault between the user interface and the main PCB.Communication channel/ebus fault on the main board, incompatibility between interface and PCB or defective connection/harness. Check the interface power supply from the board, connectors/harness and test with a known interface; if it persists, the cause is the PCB.
How do I confirm that this PCB is the correct one for my boiler?
Check the silkscreened reference S1019000 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.
