STEP 2: SECOND DESCALING SOLUTION RINSE

STEP 3: FRESH WATER RINSE

fresh water each time.

•  You may need to perform additional Fresh Water Rinse cycles if you notice any 

residual taste.
NOTE: The cleaning action of the Keurig

™

 Descaling Solution may result in  

a foam dispensed from the brewer. This is natural, as the solution is reacting 

with the scale inside. For a brewer that is heavily scaled, the brewer may 

not fill properly after the descaler is added. If this occurs, you may see only  

a small or no output dispensed followed by the sound of air blowing out.  

If this occurs:

•  Turn off and unplug the brewer.
•  Plug the brewer back in, power on, and repeat the Step 3 Fresh Water Rinse 

cycle. The brewer should begin to function normally as the solution is rinsed 

out and the scale is removed. If problem persists, allow the brewer to sit 

unplugged for at least 30 minutes before continuing with the rinse.
