Please note: PulyCaf,
Cafiza and CleanCaf are only for cleaning coffee and backflushing
commercial machines. If you are using these two as descaling
chemicals, it can harm the machine.
The first part of trouble shooting to review how
the machine was maintained. Machines mal-function if they are
not operated as recommended or not maintained as required.
Before proceeding to the trouble shooting table, please
read the following Self check:
1- Find out the hardness of water in your area
and determine the frequency for descaling. Filtered water is
not free from mineral salts. Water softener system is necessary to
eliminate minerals from water. Reverse Osmosis or use of distilled
water is OK if one can afford it.
2- How frequently has the machine
been descaled:
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 chemical
from reliable sources.
3- Check the roast of Coffee beans that are
being used? 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 the grinder has 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.
Feel the coffee pucks for the fineness. Check the fineness
frequently. It should be like the table salt grain. Powdery coffee
results in over extraction. 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
commercial machines).
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
gears.
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 power switch (not by the sleep
mode switch).
