Maintenance

Regular cleaning and maintenance will ensure optimal performance and longevity of your coffee maker.

Daily Cleaning:

  • Drip Tray: Remove and empty the drip tray after each use. Wash with warm, soapy water and dry thoroughly.
  • K-Cup Holder/Ground Basket: After each use, remove and rinse the K-Cup holder or ground coffee basket. Wash with warm, soapy water as needed.
  • Exterior: Wipe the exterior of the coffee maker with a damp cloth. Do not use abrasive cleaners.

Descaling (Recommended Monthly or Bi-Monthly):

Mineral deposits from water can build up over time, affecting performance. Descaling helps remove these deposits.

  1. Prepare Solution: Mix 1 cup of white vinegar with 2 cups of water.
  2. Fill Reservoir: Pour the vinegar solution into the water reservoir up to the 14 oz line.
  3. Run Cycles: Place a large mug on the drip tray. Run several brew cycles (without coffee) until the reservoir is empty.
  4. Rinse Cycles: Fill the reservoir with fresh, clean water and run several more brew cycles to rinse out any remaining vinegar solution.
  5. Repeat the rinse cycles until no vinegar smell remains.

Note: The coffee maker has a self-cleaning function. Refer to the product's specific instructions for activating this feature if available, or follow the manual descaling process above.
