their best, store them in a sealed
container in a cool place.
You can keep the coffee beans in the
bean container for several days
without them losing their aroma.
6.2 Checking the water hard-
ness

ness correctly so that your appliance

descaling. You can use the enclosed
test strip to check the water hardness
or ask your local water company.
Briefly dip the test strip in fresh tap
