Maintenance; Daily - Rancilio EPOCA E-S-S-Tank Use And Maintenance

1 = Time-out Heater filling level: time limit for correct
heater filling has been exceeded.
2 = Time-out Heater pressure set-point: the time
limit to reach heater pressure set-point has been
exceeded
3 = Electronic card 12Vdc short: short circuit in the
electronic card E14
4 = Capacity level sensor 12Vdc short: capacity level
sensor supply has short-circuited. (*).
5 = Pressure transducer 12Vdc short: pressure
transducer supply has short-circuited.
6 = Volumetric counter 12Vdc short: short circuit on
the supply of volumetric counters.
7 = 5Vdc push-button panel short: the push-button
panel has short-circuited.
8 = Transducer/probe short on output signal: short
circuit on output signal from the pressure tempera-
ture probe / transducer.
9 = Open transducer/probe signal: the output signal
from the temperature probe/transducer has been
interrupted.
A = Absence of volumetric counter impulses group
1: the volumetric counter of the first group is not
transmitting impulses to the electronic card.
B = Absence of volumetric counter impulses group 2:
the volumetric counter of the second group is not
transmitting impulses to the electronic card. (*).
C = Absence of volumetric counter impulses group
3: the volumetric counter of the third group is not
transmitting impulses to the electronic card (*).
d = The output signal from boiler over pressure sen-
sor has been interrupted.
(*) Only for predisposed machines.
The failures identified by numbers 1 to 9 block ma-
chine utilisation. Apart from the failure being indicated
on the display, the push-button panel LED will flash
simultaneously informing the user of the malfunction.
After having identified and resolved the failure,
switch the machine off and then on again for normal
utilisation.
NOTE: The problems identified with the letters A, B
and C do not interrupt the functions of the machine.
They are identified on the display and during dispens-
ing from the corresponding group, the LED of the
button pressed will flash.

11. MAINTENANCE

Maintenance operations have to be carried
out when the machine is off and cold and the
plug is disconnected. Some particular opera-
tions have to be effected when the machine
is operating.
Do not clean the machine by using metal
or abrasive devices, such as steel wool,
metal brushes, needles, etc. or general
detergents(alcohol, solvents, etc.)
When necessary, use special detergents
for coffee machines that can be bought in
specialized service centres.
11.1. Daily (Fig.9)
Model S and E
Use a clean cloth or sponge that does not leave hairs
or fluff (preferably cotton or linen).
 Carefully clean the outside surface, following the
grain of the satin finish on the parts in stainless
steel.
 Clean the steam and hot water spouts, check that
the nozzles are not encrusted (if they become
encrusted,be careful not to deform or damage
them).
 Clean the spray units and the seals under the
casing of the delivery units using the special brush
supplied
 Remove the filter-holders of the machine and re-
move the filters and the clamp which secures the
filter, use a brush to remove any coffee deposits
and rinse with hot water in order to dissolve any
grease deposits.
Model S TANK
Operation to be carried out when the machine
is off and cold and the plug is disconnected.
 Remove the lid on the water-tank;
 Remove the air trap C and softener A (Fig. 7);
 Take out the water-tank, empty and clean it;
 Thoroughly rinse the water-tank and replace it in
the machine;
 Place the air trap in its guide and the softener
horizontally on the bottom of the water-tank;
 Fill the tank with clean water and close the lid.
If the air trap is not in the correct position, the machine
cannot heat or indicate a lack of water in the tank.
