Steps

1. Step 1: Prepare the coffee maker

   • Turn off the coffee maker and let it cool if it was recently used.
   • Empty the water reservoir.
   • Remove any coffee pod, filter, or grounds.
   • Place an empty mug or carafe under the spout.

   Check: The machine is off and cool enough to handle. · The reservoir is empty. · No pod, filter, or used grounds remain in the machine.

2. Step 2: Add the descaling solution

   • Pour the manufacturer-recommended descaling solution into the reservoir as directed on the label or in the manual.
   • If the manual allows white vinegar, fill the reservoir with the approved vinegar-water mixture.
   • Do not overfill past the maximum line.

   Check: The correct descaling liquid is in the reservoir. · The fill level is at or below the maximum line.

3. Step 3: Run the descale cycle or brew cycles

   • Plug in the coffee maker and power it on.
   • Start the descale cycle if your model has one.
   • If there is no descale cycle, run brew cycles without coffee until the reservoir is empty, discarding the liquid after each cycle.
   • Pause if the manual says to let the solution sit inside the machine for a set time.

   Check: Liquid is flowing through the machine into the mug or carafe. · The reservoir has been fully processed as directed.

4. Step 4: Rinse the machine thoroughly

   • Empty the mug or carafe and rinse it.
   • Fill the reservoir with clean water.
   • Run a full rinse cycle or multiple brew cycles with water only.
   • Repeat with fresh water several times until there is no vinegar or descaling smell left.

   Check: Only clean water is being run through the machine. · No descaling odor or taste remains.

5. Step 5: Clean removable parts and finish

   • Unplug the machine again.
   • Wash removable parts such as the reservoir, drip tray, and carafe according to the manual.
   • Dry the parts and reinstall them.
   • Brew one final water-only cycle if desired before making coffee.

   Check: Removable parts are clean and reinstalled correctly. · The coffee maker is ready for normal use.
