3) Brew motor current
Measure whether there is a short cir-
cuit in the motor including in the wiring
to the motor.
An overcurrent of 0.6 A is detected although no brew-
ing unit movement has been triggered.
The motor/wiring is faulty.
►
Detach the motor connector from the main board.
Check the wiring and the motor for a short circuit,
beginning with the connector.
The main board is faulty.
►
Replace the board.
4) Grinder left blocked
5) Grinder right blocked
After the message "Grinder current" is
cancelled three times, the "Grinder left/
right blocked" message appears.
See the description of the "Grinder current" display
message for more information.
The "Grinder left blocked" message is
displayed for 10 minutes. During this
time, the grinder cannot be used.
►
The 10- min resting period can be shortened by
switching the machine off and on.
Faulty grinding discs.
►
Empty the grinder and check the grinding discs.
The grinder is blocked by a foreign
body.
►
Empty the grinder and remove the foreign body
from the grinder.
6) Grinder current
Measure whether there is a short cir-
cuit in the motor including in the wiring
to the motor.
An overcurrent of 0.6 A is detected although no brew-
ing unit movement has been triggered.
The motor/wiring is faulty.
►
Detach the motor connector from the main board.
►
Check the wiring and the motor for a short circuit,
beginning with the connector.
The main board is faulty.
►
Replace the board.
7) Coffee sensor defect
8) Hot water sensor defect
9) Steam sensor defect
10) Sensor steamwand defect
11) Booster sensor defect
The main board does not detect a re-
sistance. Dispensing of beverages is
blocked.
►
Check the electrical connections between the
sensor and main board.
►
Measure the resistance of the NTC sensor.
The following resistances must be measured at the
sensors at the corresponding temperatures:
•
25°C = 10,000 ohm
•
90°C = 910 Ohm
•
100°C = 678 ohm
►
Replace the sensor if the value does not corre-
spond to the values above.
12) Timeout coffee heater
13) Hot water heater timeout
14) Steam heater timeout
Although the heating is switched on,
the set temperature was not reached
within 5 min.
The "Klixon" safety equipment was trig-
gered due to overheating.
►
Reset the "Klixon" safety equipment by acknowl-
edging, or replace it if faulty.
The board is faulty (relay/thyristor).
►
Replace the board.
Poor contact.
►
Check the wiring and connections of the boiler.
The heating is faulty.
►
Measure the heating resistance and replace the
heating if faulty.
Phase missing in a 3-phase connec-
tion.
►
Measure the voltages between the phases and
correct missing phases if necessary.
