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)
F13Main PCB faultYes — it is the direct code of the PCB. Check 230 V, fuse, connectors, and grounding; if it persists, replace the PCB.
F11No signal is reaching the main circuitPossible — first rule out wiring and connectors to the PCB; if they are fine, it is usually the PCB.
F12No signal from the user interfaceNormally not — it's usually the display or its cable, not this main PCB.
F18User interface faultNormally not — it corresponds to the panel/display, not to this PCB.
How do I know if fault F13 indicates changing the main PCB S10470?
F13 = main PCB fault; if after checking mains voltage, fuse, connectors, and grounds the error persists, the candidate is the PCB. In F11, first rule out breaks or false contacts in wiring and connectors. F12/F18 do not point to this PCB (they are related to the user interface).
How do I confirm compatibility by reference and model?
Check that your PCB shows S10470 or S1047000. This same PCB is used in the ThemaClassic, Themafast, Thematek, Isotwin, Isofast (H-MOD), and Thema F25E STL families. Also cross-reference the exact model of your boiler with the exploded view.
When installing it, do you need to parameterize or program anything?
If you replace it with the same reference S10470, it does not need to be coded from scratch, but it is advisable to replicate the position of the jumpers/microswitches from the original. After installation, a technician should adjust service parameters and check combustion and safety features.
How does this PCB differ from the display or user interface?
The main PCB controls ignition, modulation, sensors, and safety features; the display is just the front interface. F12 and F18 are usually related to the display or its cable, not this PCB. If your fault is F13, it affects the main PCB.
Why does a PCB burn out and how can I prevent the new one from failing?
Typical causes: voltage spikes, shorts in the pump, fan, or valves, moisture, and poor grounding. Before installing the new one, check peripherals, clean up wiring and connectors, correct water inlets, and install a surge protector.
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.
