Seen this a few times with the coffee maker. FlexBrew does not have a dedicated reset button on the machine. People tend to asks about this since there is no button for it.
To work around this, you have to unplug the machine and allow it to sit for 5 to 10 minute prior to plugging it back in. If you simply unplug it, the flexbrew machine will not boot back up as the internal component do not discharge quickly enough. Once it is booted back up, the machine will reset the clock so you must set the time prior to brewing.
This is essentially the only “reset” these coffee maker have.

Took me a while to find this so please tell me if I missed something obvious… but for the Flexbrew coffee makers, does this 5-10 minute unplug trick work for the dual brew coffee maker as well? I have the Flexbrew coffee maker with the carafe and the pod side.
 
Well, I took one apart when the heater on my Flexbrew stopped working. It’s pretty bare bones as far as coffee makers go with just the MCU and a small electrolytic capacitor on the 5v rail. There doesn’t appear to be a supercap or any form of battery backup so the clock will die if I unplug it. 30 seconds to a minute should be plenty of time to drain that capacitor so the 5-10 minute trick sounds like a myth that has been copied and pasted in forum posts for years.
 
After flexbrew coffee makers flashing the clock for me and refusing to take any button presses I simply unplugged it for about 2 minutes and it started working again. I’ve found that taking it out for about 30 seconds works but 10 minutes sounds like grandma’s advice.

They are essentially the same board and the dual brew just has a second relay to control the pod side of the coffee maker.

The microcontroller can get into a weird state so the small capacitor on the power rail keeps it juiced up. That’s why you have to unplug for 30 seconds.

Wait, that does make sense. The small capacitor keeps the power stable so that the brownout detection does not fire up? Would it not be better to just use a supercap or battery backup so it would not matter if I unplugged the coffee maker?
