15. SETTING IN OPERATION:
1. Supply voltage through the main switch upstream from the appliance.
2. Turn the water tap on.
3. Make sure that the filter and the overflow are placed in the correct position.
4. Shut the door and press switch (2); the machine starts filling up with water and detergent.
5. Once the machine has been loaded (from 1 to 4 minutes depending on the type of machine and the
supply pressure) the boiler heating elements automatically come into effect followed by the bowl
heating element once the boiler temperature (85°C) has been reached.
If it is necessary to open the door when the machine is running
AVOID DOING IT TOO QUICKLY.
Although the appliance is equipped with a safety switch to prevent the door from opening suddenly, spurts of
water could still reach the user in the event of a hasty manoeuvre.
The machine is equipped with a programmer which switches on by briefly pressing the cycle (3) start up button
NORMAL OPERATING CYCLE:
O
nce the machine is ready to operate as per the “SETTING IN OPERATION” paragraph, follow the
instructions below to run the desired wash cycles :
❑ Insert the rack with the soiled crockery and shut the door;
❑ Select the long or quick cycle switch (6) press the cycle (3) start-up button. The indicator light (4) will
illuminate when the machine has started the selected wash cycle.
In case of accidental door opening the washing cycle will stop and the pilot light (4) will flash at intervals (1
sec.). Once the door will be closed again, the cycle will restart from where it has been interrupted.
Once the cycle has finished, the indicator light (4) will switch off.
Open the door, extract the rack with the clean crockery and insert another rack, which has been previously
loaded, into the dishwasher for the next wash cycle.
N.B. : If the instructions have been followed correctly the crockery will be perfectly clean, dry and
hygienically safe. In order to avoid wasting these efforts, make sure that crockery is stored in
areas having the same requisites.
16. DECALCIFICATION AND REGENERATION OF RESINS
Some dishwasher models are equipped with a system for water decalcification and the regeneration of ion
exchange resins in salt water.
DECALCIFICATION :
the system is designed for decalcifying the inlet water that runs through the boiler
(without any external intervention).
REGENERATION OF RESINS: a regeneration of ion exchange resins in the water softener is required at
regular intervals depending on the hardness of the inlet water (see table) and must be carried out as follows:
The machine is set to do the regen program every 50 washing cycles; the warning light (4) will start to blink
when the regen program is requested. You can only stop the blinking by starting the regen program.
a) Switch off the machine by pressing switch (2)
b) Remove the overflow to drain the bowl (for equipment with drain pump press the button (7) the
draining and regeneration will start on sequence.
c) Once the bowl is empty, unscrew the threaded cap (located inside at the bottom of the bowl) and
pour in 1 kg of sodium chloride (large-grained kitchen salt). One load is generally sufficient for ¾
regeneration.
d) Shut the door and press button (7) until indicator light (8) remains on. In case of accidental door
opening the regenerating cycle will stop and the pilot light (8) will flash at intervals (1 sec.). Once the
door will be closed again, the cycle will restart from where it has been interrupted.
e) After approximately 20 minutes indicator light (8) switches off signalling that the regeneration cycle
has terminated.
f)
Normal operation can be resumed by following the instructions at paragraph “SETTING IN
OPERATION
”
N.B. : It is advisable to perform the regeneration process during periods in which the machine is not used.
Failure to carry out the regeneration process according to pre-defined intervals will cause
the decalcifyer to clog up and the amount of water supplied to the rinse jets to decrease.
