Descaling
Calcium deposits (“scale”) from water will build up in the Coffee 
Maker heat pump over time and impair brewing efficiency and 
coffee quality. With normal use, scale should be removed every 
three months or whenever the water filter icon appears on the brew 
timer display. Local water conditions, use of the Coffee Maker more 
than once a day, or use without a water filter may require more 
frequent descaling. 
The following conditions indicate an immediate need for descaling:
 the presence of loud sounds during brewing
 a brewing time greater than 10 minutes for 12 cups of coffee
 the appearance of “E1” or “E2” on the brew timer display
Mixing The Descaling Solution
The Coffee Maker can be descaled using a packaged descaling 
agent or vinegar.
 When using a descaling agent, follow the directions on the 
package for the recommended amounts of descaling agent and 
water to use.
 When using vinegar, fill the carafe with a half vinegar and half 
water solution.
Descaling Steps
1.
  Before descaling, always remove the water filter (see “Installing 
the Water Filter” on page 13) and make certain the brew basket 
contains no coffee or coffee filters. 
2.
  Run the Coffee Maker through a complete brewing cycle using 
the descaling solution. If the Coffee Maker has not been descaled 
for an extended period, run it through a second brewing cycle 
using fresh descaling solution. 
3.
  Rinse the Coffee Maker by running it through two brewing cycles 
using fresh, cool water. 
4.
  Wash the brew basket, brew basket insert, carafe, and carafe lid 
in hot, soapy water and rinse with hot water. These parts can 
also be washed in the upper rack of the dishwasher.
5.
  Reinstall the water filter and reset the water filter icon if 
necessary (see page 23). 
Error Codes During Descaling
If “E1” or “E2” error codes appear during descaling, unplug the 
Coffee Maker for 30 seconds to reset the display, then plug it back 
in and continue. If error codes continue to appear after cleaning, see 
the KitchenAid Canada Warranty and Service section on page 33.
