5.3 Monthly maintenance
Not performing the monthly mainte-
nance work has a harmful influence on
the quality of the ingredients and can
lead to malfunctioning of the machine.
Apart from the weekly maintenance,
the following tasks have to be
performed monthly to ensure a correctly
operating machine and an optimal
quality of the coffee.
Step 1. Cleaning the coffee- and topping
canisters with water
1 Remove the coffee canister and
empty it (6.2).
2 Remove the topping canister and
empty it (see 6.3).
3 Rinse out the canisters with warm
water until all coffee and topping
residues are removed.
5 Make sure that each canister is dry
inside and outside. If it is not
completely dry, the coffee may form
lumps, which may block the system.
6 Fill the topping canister and replace
it into the machine (see 6.3).
7 Replace the coffee canister into the
machine and fill it (see 6.2).
8 Open the canister locks (5.2 step 2).
Step 2. Running a cleaning cycle
1 Press the program key on the service
keyboard twice.
3 Select the cleaning cycle.
4 Place a cleaning pill in the CoEx®
brewer.
5 Place a jug under the brewer outlet.
6 Click the brewer outlet down and pull
the lock forward (5.1 step 4).
7 Press ‘>’ enter to start the cleaning
cycle, which takes about six minutes.
8 Unlock brewer outlet.
