Level 3:
If you have not been using your machine intensively,
when it may be quite normal for the motor to overheat
and trigger the thermal relay and/or overload
protector:
- If the test indicates that the thermal relay is faulty,
check that the latter is correctly set (automatic
position and current intensity in accordance with
the diagram);
- If the test indicates that the motor overload
protector is faulty, check the latter's wiring;
- If a «voltage» or «Phase + Frequ» error message
is displayed, check that the machine is supplied
with the correct voltage. Also check that the plug
is correctly wired.
- If a «Jumpers + KFR» error message is displayed,
check that the location of the configuration jumpers
on the board corresponds to that indicated in the
electrical diagram, according to the mains supply.
* If the latter problems persist, the control board must
be changed.

The flashing of the green light indicates which
element needs to be checked.
A rapidly flashing light indicates that either the base
(ISBC) or the lid (ISCO) presence sensor is posing a
problem. Press button I to determine which of these
two components needs to be checked. If the light
continues to flash the same way as before when you
press button I, check the lid arm sensor.
If, on the other hand, the light starts to flash more
slowly and asymmetrically (longer off than on),
check the lid sensor.
Asymmetrical flashing (longer on than off) means
that the bowl sensor needs to be checked (ISCU).
Slow flashing means that either the contact of the
STOP button (BPA) or the motor protector (PTO) is
posing a problem. Press button T to determine which
of these two components needs to be checked. If the
flashing does not change when you press button T,
check the contact of the STOP button.
If, on the other hand, the flashing becomes
asymmetrical (longer on than off), check the motor
overload protector.
For further details about the tests, see the previous
paragraph on dual-speed models.
