Most likely cause is a power supply issue. Check the unit is plugged in and the outlet is functional. If plugged in, try a different outlet. Power surges can trip internal protection; unplug the unit completely for 30 seconds, then plug it back in.
- Ensure the water reservoir is not empty. A dry safety feature can prevent startup.
- Check the power cord for damage. Do not use if the cord or plug is damaged. Call customer service for replacement.
- After a power outage, the clock may need resetting, but this shouldn't stop the brew function.
If the unit is plugged into a working outlet, has water, and still won't turn on, there is likely an internal fault. No user-serviceable parts inside. Discontinue use and call the provided customer service number for repair.
