7.4.6 MOTOR INOPERATIVE
This control system is operative during the entire washing cycle.
Ä Jamming of the motor is detected by the tachimetric sensor; this also makes it possible to check
for a faulty tachimetric sensor using the following procedure.
Ä When the motor is switched on, it must reach a speed of 2000 rpm within 5 seconds; if this does
not occur, an alarm condition is generated.
Possible causes:
a. Motor winding interrupted / short-circuited
b. Motor jammed (foreign bodies / pump unit)
c. Electrical connections broken / loose
d. Capacitor interrupted/short-circuited
e. Tachimetric sensor broken / short-circuited
To check that the tachimetric sensor functions correctly:
Ä Check that the voltage across the terminals of the sensor is higher than 7V AC.
7.4.7 WASH MOTOR TRIAC SHORT-CIRCUITED ALARM [A L 8]
This control system is operative during the entire washing cycle.
Ä The electronic control system identifies that the motor is correctly powered and detects the
reason for a malfunction.
Ä If the microprocessor identifies a signal from the tachimetric sensor indicating that the motor is in
operation when it should be switched off, an alarm condition is generated.
Possible causes:
a. TRIAC on control board short-circuited
Ä Replace the control board.
