What does fault code F05 mean in Cointra?

Fan anomaly. The extractor is not receiving 230 V, is blocked, or does not deliver a tachometric signal; the PCB detects a fan fault. Check voltage at the fan connector, free rotation/consumption, and tacho signal/coil continuity.

What does fault code A05 mean in Cointra?

Activation of fan protection. The extractor protection is activated due to lockout/overcurrent or due to inconsistency in the speed signal. Check motor consumption, free rotation, wiring, and rpm/tachometric input reading.

What does the F20 code mean in Cointra?

Combustion control anomaly. Incorrect air flow due to extractor fault prevents maintaining combustion within parameters. Verify that the fan reaches target rpm and flow (tacho signal), as well as air/flue ducts and diaphragm.

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.

Code	What does it mean?	Cause and diagnosis (this part)
F05	Fan anomaly.	The extractor is not receiving 230 V, it is blocked or not delivering a tachometric signal; the PCB detects a fan fault. Check voltage at the fan connector, free rotation/consumption, and tacho signal/coil continuity.
A05	Fan protection activation.	The extractor protection is activated due to lockout/overcurrent or speed signal inconsistency. Check motor consumption, free rotation, wiring, and rpm/tachometric input reading.
F20	Combustion control anomaly.	An incorrect airflow due to a fan fault prevents maintaining combustion within parameters. Verify that the fan reaches target rpm and flow (tacho signal), as well as air/flue ducts and diaphragm.
