Clean out the Machine

Unfortunately, descaling solution can leave a bitter and unpleasant taste in your espresso machine . This is due to the solution residue. To get rid of it, rinse out your water reservoir and refill it. Use clean water to run the machine through its process at least two to three times.

Make a Pot of Coffee
