Descaling Process

Descaling Supplies Needed:

  • Keurig Descaling Solution or white vinegar
  • Fresh water
  • Large mug (minimum 10 oz)
  • Measuring cup

Step-by-Step Descaling

  1. Prepare Machine: Empty the water reservoir and drip tray. Ensure the machine is powered on.
  2. Mix Solution: Fill the reservoir to max line with either Keurig Descaling Solution or a mixture of equal parts white vinegar and water.
  3. Start Descaling Cycle: Place a large mug on the drip tray. Press and hold the 8oz and 10oz buttons simultaneously for 3 seconds to enter descale mode.
  4. Brew Without K-Cup: Lift and close the handle without inserting a K-Cup. Select the largest cup size and begin brewing.
  5. Repeat Process: Continue brewing until the "Add Water" light illuminates. Discard the liquid in the mug after each brew.
  6. Rinse Thoroughly: Empty reservoir, rinse thoroughly, and refill with fresh water. Repeat brewing process 12 times with fresh water to rinse system.
  7. Final Check: Once complete, the machine will exit descale mode automatically. Discard the first post-descaling brew.
Frequency: Descale every 3-6 months or when the "Descale" light illuminates, depending on water hardness and usage frequency.
