There are grounds in my coffee.

  • Either the permanent filter or a paper filter must be inserted into the filter holder when brewing.
  • Using too many grounds can cause the filter holder to overflow. Once cooled, clean out the filter holder and refill using the appropriate amount of coffee (1 scoop per cup).
  • Finely ground coffee can clog the filter holder. For best brewing results, use a medium-grind coffee.

The paper filter is folding over.

  • The unit is designed to take a #4 cone filter. Be sure you are using this size and shape, as larger sizes may fold over. Allow the filter holder to cool before handling. Be sure the paper filter is folded along its two seams and is pressed firmly into the filter holder. Alternatively, you can wet the sides of the paper filter to temporarily adhere it to the filter holder.
  • If the problem persists, try using a permanent filter instead of a paper filter.

Coffee is too weak.

  • For a stronger coffee, use the Rich Brew setting, try darker-roast grounds, or use the permanent filter rather than a paper filter. If you want an even bolder flavor, you can add more coffee grounds. Additional grounds do absorb water, so you may get more concentrated coffee but overall less liquid volume.

Coffee is too strong.

  • For milder coffee, try the Classic Brew setting using light-roast grounds and a paper filter rather than the permanent filter. If you want an even milder flavor, you can use fewer grounds.

Carafe overflowed.

  • The carafe may not have been empty before brewing, or the water level exceeded the Max Fill line on the water reservoir before brewing. Reminder, DO NOT add additional water to the reservoir after a brew or cleaning cycle has already started.
  • For Classic brew, the carafe holds 60 fl. oz. To avoid overflows, make sure the carafe is empty before brewing and the water reservoir is not filled past the 12-cup Line.
