CHAPTER 5: COMPONENTS

The Base:

The base is in plastic and contains all the functional-parts of the dishwasher as well as acting as support for the wash-basin.

Built-in dishwashers are provided with three legs that are for the purpose of levelling out the machine: two are on the fore-front

and one at the back in the middle of the machine which is equipped with an adjustable-nut.

One of the advantages provided by the new type of base is that it facilitates access to the motor-room from the front-door

opening via two locking-hooks.

The small Basin placed under the dishwasher, may be removed by unfastening further two hooks and extracting it towards the

front part of the machine.

NB: Should the hooks that lock the front-door of the base or the basin be damaged, the base has been equipped with

self-rivetting screws, which will seal the components well and so avoid having to replace the entire base.

Adjustable Legs:

Three legs serve to adjust the height of the machine and to level it out horizontally. The front-panels must be adjusted directly by

the leg. The back-leg of the dishwasher may be adjusted by means of a hexagonal screw placed in the middle front part of the

machine, under the connecting Hardware-key hole.

"Brushless" Motorpump for Washing-cycle (BLDC):

Introduced on machines in the top range. The main feature is its silent motor.

Another specific feature of this motor is given by the fact that it is possible to keep control of the rotational speed thus modifying

the water-pressure favouring the additionof other options as on this model eg. GOOD NIGHT AND SHORTIME.

Alternate Washing Motor

Its principle function is to control the washing in both drives. It pushes the water only towards the upper syphon, and then on the

lower one and so forth and so on.

If the programme is to last less than an hour, both rotors are made to work simltaneously in order to ensure high quality in the

performance.

It also permits the User to choose just one rack to wash the dishes in.

Water Heater:

The water-heater has been mounted on the Archimedian water-pump.To disconnect or replace the water-heater, one needs only

to rotate the Water-heater/motor in an anti-clockwise direction and to draw it out.

The "O-Ring" serves to prevent any water-leakages from taking place; so care must be taken when fixing it back into place again

and it must often be checked for water-leakages.

Water Stop:

Placed at the beginning of the water-pump, it serves to check the inflow of water into the dishwasher, as well as preventing any

water from flowing in should there be an anomaly on the machine.

The fill-capacity has been reduced to 2.5 litres a minute, thus the filling-time has been prolonged favouring less noise. It is

controlled by an eletronic-board by means of a triac.)

Airbreak:

The Airbreak is placed on the left-hand side of the machine and its functions are:

1.To prevent the water from going back into the water-supply system once it has entered the machine.

2.Airbreak (venthole)

3.To allow at least 3% unsweentened water to be introduced which will prevent excessive formation of foam.

4.To contain the Turbine Litre-count

As compared to the former one, this Airbreak does not store any water. It must be remembered that the regeneration-cycle of the

resines on this model, differs to the previous one.
