1. Water intakes in all programmes are realized by water level sensor. Whether
or not the water level has dropped below levels determined according to the
steps is checked by the water level sensor. If the water level has dropped,
water will be intaken against checking the the water level sensor.
2. Top closure algorithm is applied during programme startup.
TOP CLOSURE ALGORITHM
Is main wash at the
beginning of the step?
Take water from
CV1 for 6 seconds
Yes
Drain for 1 second
Wait for 2 seconds
No water test
Wait for 10
seconds

3. Later water intakes are realized according to the levels determined according
to the programmes. If the selected programme temperature is 60C or higher
than 60C, water intakes are made via hot water valve. Otherwise, water is
taken through cold water valve.
4. Amount of load in the machine is determined according to number of valve
opening in this step. Max. water intake number may change according to
energy declaration target.
Depending on the low, medium or high load, washing parameters such
as heating step time, rinse water amount are changed.
5. When water level drops below Psafety (Pg) level in washing steps during and
after heating, heater is turned off. Water is taken from the main wash valve.
Top closure algorithm is not applied
under following conditions:

If previous programme is
cancelled and a new programme
started, top closure algorithm is
not applied in the newly selected
programme.
