This message comes up after I have emptied the coffee grounds. I did some research and it looks like it might be getting wet inside the door so I take the brew group out every night and leave the door propped open to try and dry it out. This sometimes helps as the message will briefly go away in enough time for me to make my coffee in the morning. Is there anything else I can do about this problem.? I usually only get two coffees to work before the message comes back and stays back. Thanks for any help.
