When to Seek Professional Service
If you experience persistent issues such as failure to power on, strange smells, persistent error messages, or physical damage, it is best to contact COSORI customer service or a qualified technician. Do not attempt to disassemble or repair the unit yourself, as this could void your warranty and pose safety risks.
