Priming after long periods of non-use

Descaling

For the best tasting espresso, prime the Espresso Machine with fresh water after a long
period of non-use. Priming will also ensure that the boilers are filled and the Espresso
Machine is ready to operate.
Calcium deposits (“scale”) from water will build up in the Espresso Machine over time
and may impair espresso quality. Scale should be removed every four months; local
hard-water conditions may require more frequent descalings. Use a packaged descaling
agent or appropriate decalcification tablets to remove scale. These can be found online,
or at coffee specialty shops. KitchenAid does not recommend using vinegar and water
solutions or home remedies in place of a commercial descaler for the Espresso Machine.
1Remove the shower screen from the
brew head. See “Cleaning the shower
screen” section for instructions.
2Make certain the water reservoir
is empty. Following the directions
on the descaling agent packet, mix
the descaling solution and add it
to the reservoir.
