The error code is detected during the wash phase in which the washing motor is ac-
tive.

If no change of state is detected at any time during the program when the electronic 
module activates the motor distributor in order to change the position status of the 
motor distributor, this will be indicated by the error code F9.

The change of state will be determined by a change of positioning of the distributor, 
which is detected by the cam; this is detected in turn by the electrical contact, which 
informs the electronic module of this change.

If this type of malfunction occurs, the dishwasher will stop and the buzzer will sound 
as follows:

9 beeps 

 Pause  7 sec. 

9 beeps 

pause 7 sec………

and so on, successively.
