Welcome. My name is ***** ***** would be glad to assist.

If “E1” or “E2” appears on the brew timer display:

The coffee maker needs to be descaled. Unplug the coffee
maker for 30 seconds to reset the display, then plug it back in

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, mix a solution of 6 cups vinegar and
6 cups water.
Descaling Steps
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.
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.
Rinse the coffee maker by running it through two brewing cycles
using fresh, cool water.
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.
Reinstall the water filter and reset the water filter icon if

If it still continues with the error code after descaling, it will need to be sent in for servicing.
