Please Note: PulyCaf,
Cafiza and CleanCaf are only for cleaning coffee and backflushing
commercial machines. If you are using any of these as
descaling chemicals, it can harm the machine.
The first part of troubleshooting to review how
the machine was maintained. Machines malfunction if they are
not operated as recommended or not maintained as required.
Before proceeding to the trouble shooting table, please
answer the following questions and review the statements
1. What is the hardness of water in your area?
Find out and determine the frequency for descaling. Filtered
water is not free from mineral salts. Water softener
systems are necessary to eliminate minerals from water. Reverse
Osmosis or use of distilled water is OK if one can afford
2. How frequently has the machine
a. Over one year
ago (very poor attention)
b. Every six
months (not enough)
c. Every three
months (fair maintenance)
d. Every two
months (good maintenance)
e. You are
descaling the machine as recommended but using the wrong chemicals -
Purchase descaling chemicals from reliable sources
3. What roast of coffee beans are you
using? Oily beans are not recommended for use in fully automatic
espresso makers. Manufacturer's warranty will be void. Oily beans
are like a slow poison for the following models: Charisma, Italia, Italia Digital, Divina Deluxe, Syncrony
Compact, Syncrony Compact Digital, Incanto Sirius & Incanto
Easy. These models have a longer tunnel through which ground coffee
moves from grinder to the doser; oily coffee grounds jams the tunnel
and cause malfunction.
4. How frequently has the grinder been
cleaned? If oily beans are used, the grinder and doser parts
should be cleaned once every month.
5. Fully automatic machines do not need
powdery grind. Check fineness of coffee grounds frequently and
feel the coffee pucks for the fineness. The finesness of the coffee
grounds should be like table salt grain. Powdery coffee results in
over extraction and as a result, espresso will be bitter and
without crema. The load of pumping water increases tremendously on
the pump and life of the pump will be shortened.
6. The extraction time with pre-infusion in
fully automatic home models is much shorter (12 to 14 seconds
for 2 oz.) than in traditional machines (do not pay attention to
exchange of information on various forums, those discussions are for
7. If you like Cafe Americana, increase the
quantity by adding hot water instead from the machine. Avoid
extended extraction time as it will burn the coffee grounds and
coffee will be bitter.
8. For stronger espresso, reduce the amount of
water per shot instead of increasing the dose of coffee grounds.
If one shot of 2 oz. espresso is not
enough, use two or three shots. Careless increase of coffee in
automatic machines can damage the brew drive
9. Do not leave the home espresso machine "ON"
when not in use. The commercial traditional machines are left on 24
hours for different reasons that do not apply for home models.
Always turn the machine off using the power switch (not by the sleep
