The amount of detergent poured into the bowl depends on the amount of water consumed by the machine
during each rinse cycle.
The amount required may range between 0.8 and 2.5 grams/litre depending on the detergent type and
concentration.
11.2
OPERATION
Since the control is parallel to the load/rinse solenoid valve, when the machine is filled with water, the
dispenser adds the detergent according to the amount established by the manufacturer.
When the rinse cycle starts, the load/rinse solenoid valve allows the dispenser to replenish the detergent in
the bowl.
N.B. The setting of the operation of the dispenser must find a balance between the initial loading and
replenishing, by adjusting the operating time in relation to the intervals.
One second of dispenser operation corresponds to the input of one gram of product
11.3 HOW TO REGULATE THE DETERGENT DISPENSER
The regulator was designed to allow the dosage of detergent that normally flows through the dispensing
pumps.
Specifically this regulator carefully balances the two amounts of detergent (the initial and replenish ones)
which periodically are loaded into the machine.
By fully turning the timer anticlockwise the pump is always off, whereas by turning fully it clockwise the pump
is always on.
The intermediate settings of interval/operation are exemplified in the diagram below:
11.4 EXAMPLE OF HOW TO SET THE AMOUNT OF DETERGENT REQUIRED
Measure the water consumption of each rinse cycle by referring to the technical sheet of the appliance.
For example, let us assume that the consumption is equal to 2 litres:
2 lt of water x 1.5g (hypothetical amount of detergent recommended by the manufacturer for every litre of
wash water, taken from the product technical sheet) = 3 (gr. of detergent).
Given that 1 gr. = 1 cc. of detergent takes up 8 cm. of the transparent supply tublet of the dispenser, this
leads to: 3 (gr. of detergent) x 8 (cm. of tublet) = 24 (cm. of tublet corresponding to the volume of required
detergent).
The setting must be carried out so that the appliance produces an amount of detergent equal to 24 cm. in
length of the supply tublet, for every rinse cycle.
By following the same criteria, the consumption of every other dishwasher model can be calculated.
N.B. The data provided above refers to a standard supply tublet with a diameter of 5 mm
The amount of detergent is right when the crockery is free from any food residues at the end of the wash
cycle.
An excessive amount of detergent can give rise to the build-up of foam in the bowl and leave white streaks
on the crockery.
Insert the overflow in its housing and carry out some trial cycles.
Perfect wash results can be guaranteed by gradual setting.
N.B. Extra care must be taken in achieving a perfect balance between the amount of rinse aid and
the amount of detergent.
Do not immerse your hands in the wash lye. Should this happen rinse immediately with plenty of water.
Place the dishes with the cavity facing upwards and the cups and glasses upside down.
Place the saucers in the appropriate rack support and the knives and tea spoons in the cutlery basket with
the point facing downwards.
Do not place silver and stainless steel cutlery in the same container as this may cause silver to burnish and
stainless steel to corrode. If possible, wash glasses and glass dishes before the wash cycle.
Place the various types of crockery into the appropriate baskets (plates, glasses, mugs and cups, saucers,
cutlery etc.).
