7.3 Water filling time
The maximum time that the fill solenoid stays open is subdivided over the various sub-phases in the
fill cycle.
7.3.1 Static filling time
S.T. = max 90 seconds:
this is the maximum time allowed for the pressure switch to switch to
FULL. If the switch does not move to FULL within the established time, the electronic control system signals
an alarm [
1 0
] and interrupts the washing cycle.
7.3.2 Dynamic filling time
D.T. = S.T. x 3:
this is the maximum time allowed for the pressure switch to switch to FULL during
the entire fill phase.
•
If the pressure switch does not switch to FULL within the time allowed (
S.T. x 3
) the electronic control
system shuts off the fill solenoid and the heating element (if it is on), and then completes the washing
cycle. When this occurs, alarm [
F0
] is stored internally but is not shown to the user. The alarm can only
be displayed to the service technician through a specific procedure.
•
During dynamic filling at 2800 RPM, if the pressure switch fails to switch to the FULL during the first 60
seconds, the electronic control system signals an alarm [
1 0
] and interrupts the washing cycle.
7.3.3 Interruption
of
water
filling
If the fill cycle is interrupted by opening the door or by a power failure, the elapsed time up to that
point is stored. When the door is closed or power is restored, water filling resumes from the point of
interruption and the operating time from that point is added to the previous time.
7.4
Washing
system
This appliance features the conventional washing system in
which mechanical washing action is obtained from the wash pump,
which circulates water through the water circuit and rotates the two
spray arms simultaneously.
The wash pump, which is equipped with a tachometric
generator, is powered by an asynchronous motor equipped with a
starting capacitor (3µF – 450V).
The motor rotates anti-clockwise (as seen from the side of the impeller).
To optimise washing performance, this appliance offers two different washing systems:
«
ctrl
»
Washing at a constant motor speed of 2800 RPM.(max. motor speed).
«
PW
»
Variable-speed (pulse) washing at 1600 > 2800 RPM. This system is controlled by the
electronic control system, which sequentially activates the washing motor at two different
speeds (a minimum and maximum speed) for brief intervals.
MOTOR SPEED
PERIOD OF TIME

1600 RPM

The motor speeds for «ctrl» and «PW» can be programmed; for further information, see the table of cycles
for the specific model.
