Before we delve into specific problems, remember to check the basics: is your machine properly plugged in? Is the water tank filled correctly? Are the filters inserted properly?

If your FlexBrew machine isn't brewing coffee, first ensure that the water reservoir is filled with fresh, cold water. For the full pot option, make sure you're using the correct carafe that came with your machine.

If the issue persists, unplug the machine, remove and clean the drip tray, thenclean the brew head. Sometimes, grounds can get stuck and hinder the brewing process.

Machine Brewing Slowly

If your FlexBrew is brewing coffee at a snail's pace, try descaling your machine. Limescale buildup can slow down the brewing process. You can descale your machine using a mixture of vinegar and water, or you can use a descaling solution specifically designed for coffee makers.

Also, check if the water is flowing freely from the reservoir to the brew head. If not, you may need to flush the water tank with water and vinegar to remove any blockages.

Why is my Hamilton Beach FlexBrew blinking?

If your Hamilton Beach FlexBrew machine is displaying blinks or lights that aren't turning off, it's usually an error code or warning. The specific blinks can indicate different issues:

  • One quick blink: Coffee brewing stopped prematurely. Check for clogs or ensure you're using fresh, cold water.
  • Two quick blinks: Water also detected in the drip tray area
  • Four quick blinks: Machine needs descaling
  • Nine quick blinks: Machine needs to be reset
  • Fifteen quick blinks: Brewed coffee detected in reservoir, clean the machine
