Yeah, this one's common. A power interruption—like a brief outage or surge—hit mid-cycle. The flashing clock is the tell.
First, just unplug the unit from the wall outlet for a full minute. Then plug it back in. That should reset the electronics. You'll need to reset the clock time, but the brew function should work again.
If it stops mid-brew again, check that the carafe lid is securely in place. The unit might have a safety sensor that halts brewing if the lid is off. Also, make sure you're not using an extension cord that can't handle the wattage—it can cause voltage drops. If the problem keeps happening on a known-good outlet, there might be an internal fault. Since there are no user-serviceable parts, you'd need to call service.
