January
Is your home in a high altitude? Clean it with vinegar as suggested in another post. Add more coffee, or try another brand. Maybe the coffee you have been buying isn't as potent as it once was.
Or, you could have gotten a bad pot. I have had mine for 29 years. I use it maybe once a year, but it still makes a potent cup of Joe....too potent sometimes, Yikes!
Good luck
