Cosori Air Fryer E12 — What It Means & How to Fix It
E12 is the DC-motor failure code on newer Cosori models.
What this code means
From Cosori's CPDV / Shake Reminder manual: 'Display shows Error Code E12 — The DC motor has failed. Contact Customer Support.' This is a motor-hardware fault, not recoverable by user reset.
Cosori's user manual for the CAF-SE601S-CUS says E12 means the DC motor has failed and directs owners to Customer Support. That manual writes the other codes as E01 to E04. Codes differ between Cosori air fryer models, so check the model number on the underside of the unit against its own manual.
