1 - INTRODUCTION
The objective is simple : the matter is to make the dirty dishes clean. The quantity, nature, dirt level of the dishes, the cleaning product used, or even the water hardness may act against the expected result.
So far, all these parameters have been left to the assessment of the consumer, who alone assumed the responsibility for poor wash. Increasingly, the new ATLANTIS dishwasher consider all these factors.
The intelligent use of some sensors enables the electronics to adapt the run of its auto-programs, in order to guarantee the result while trying to save water, energy and time, and this, whatever the load or dirt rate is.
The new ATLANTIS dishwasher provides reduction in water, energy consumption, and cycle times while assuring A level in washing and drying.
To perform the dishwasher maintenance, the technician has to identify the cause(s) at the origin of the consumer's claim. To do so, he has to make a precise diagnostic in order to adopt the appropriate for the encountered problem.
The new ATLANTIS dishwasher proposes a programme of aid to diagnostic intended for the after-sales department. Only the rigorous and systematic implementation of this programme can definitely assure the action reliability.
A properly performed after-sales action should favour the development of customer’s loyalty to the sales outlet, to the sign and also to the trademark concerned.

2 - THE ENERGY LABEL
2.1. - What you must know
Washing machine, dryer and dishwasher are three appliances likely to weigh heavy on the electricity invoice if you choose model poorly classified from the energetic point of view. Washing machine and dishwasher each consume about 250 kWh a year. For a few years, the manufacturers have made efforts on the water consumption, which has a direct effect on the power consumption at the moment of the heating.
Initiated by the European Community, this labelling is now compulsory in France for most household electrical appliances. The classification from A (the most economical) to G (the most avid on electricity), enables the consumer to locate at a glance, the various models proposed. For washing machines, an additional indication concerning the wash and spin, complements the information concerning the power consumed.
This mention must appear compulsorily on all the dishwashers marketed from the 1
st
of January 2000.
The “Bio” programme is selected to laboratory tests.

3.2. - The advantages of the dishwasher
A family of four persons devotes 55 minutes a day on average to do dishes, against 20 minutes when it has a dishwasher. The cost of a dishwasher is written off in only 3 years and its estimated lifetime is approximately 10 years. Washing up in machine is much more hygienic because dishes are perfectly washed and dried without contact with external elements (towels, hands or work surface), which often convey a number of bacterias.

3.3. - The sound level
Noise remains a selection criterion essential despite the fact that indicating it on the "Energy Label" is not compulsory.
For the ATLANTIS dishwasher, the level is comprised between 45 and 51 decibels (dB). It must be known that a variation by 3 decibels multiplies by two the sound volume and this is only below 50 decibels that the dishwasher can be operated late at night. To achieve this result, several improvements have been made to the ATLANTIS dishwasher :
PTC and double auxiliary winding for certain asynchronous cycling pumps
Reinforced acoustics (double-thickness bitumen, felts, phonic seals)
Passage of the entire spraying circuit in the tank.
3.4. - The drying
The drying result is an important point that appears on the "Energy Label".
The ATLANTIS dishwasher proposes 3 marks for the drying (A/B/C), according to the dishwasher level of equipment.

3.5. - Operating principle
Dirt adheres to dishes with a certain energy that is to be overcome to get rid of it. It is, therefore, necessary to implement the following actions:
The mechanical action (aspersion)
Its purpose is to project the detergent bath onto dishes to remove and drag the dirt. The ATLANTIS dishwasher is provided with 4 spraying levels:
Two that spray the lower and upper baskets
A third one, multidirectional (small shower) attached to the tank ceiling prevents residues from
depositing on the tank ceiling and falling during drying
A fourth one, carried out using a rotary nozzle assembled to the lower winch in certain models, is
used to better clean the bottom of saucepans (it is associated to a specific program).
Spraying the dishes is performed by the winches, which turn simultaneously or not (alternate spraying) under action of the water pressure in spraying nozzles. The water thus projected onto dishes falls in the tank bottom where it is purified by flowing through four filters. These filters perform continuous recycling of the detergent solution until cycle end. The water is then returned, pressurised, by the circulation pump (approximately 50 litres / minute) into the spraying arms. Such a circulation and the low volume of the cycling unit volume (1.85 litres) are used to have a total water consumption relatively low (12 litres), as each piece of dishes is washed by only one volume of water (approximately 4 litres). After wash, the wastewater is evacuated, the clear water, cold for the first rinse rinses dishes, and then a second rinse, hot, precedes the drying.
The thermal action
The progressive temperature rise and the achievement of an enzymatic dwell at 50°C are used to obtain the best conditions of elimination of all the types of dirt. Actually, the action of the various components of detergent products varies according to the bath temperature.
The chemical action
When dishes are done in machine, the mechanical action is limited (as compared with dishes done by hand), and must therefore be compensated for by a more powerful chemical action. To the mechanical and thermal energy of the machine are added the physical-chemical and biological actions of the detergent. As the nature of dirt is very varied, it is not always eliminated in the same way. This is the reason why detergents contain very different components and, in particular, enzymes.
The duration.
All is not as simple. If we detail the operation, we remark that an essential element is missing : the water. Actually, without water, there is no wash! The water will, with the support of active principles of the detergent, destroy, eradicate, dissolve and emulsify the dirt present on dishes. It will do so all the better since the machine will water the dishes and heat the water. The wash result depends, therefore, simultaneously on 4 factors :
The washing product
The water
The temperature
The mechanics
A good wash result can, therefore, only be obtained if all these conditions are respected.
Spraying arms project onto dishes (mechanical action) a solution of detergent products (chemical action) progressively heated by a resistor (thermal action)

THE WATER
- 10 -
LA3-ATLANTIS-002UK-04/04
4 - THE WATER
The water covers, in the nature, a cycle due to its continuous evaporation under the action of the sun heat; this vapour is condensed into fine droplets to produce clouds, which are transformed into rain when they meet a cold air draft.
It is possible to assert practically that this is from the moment where the rain starts falling that it begins to lose its purity. Actually, during its fall, the rain meets in the atmosphere a certain number of impurities of variable nature, among which carbon gas with which it is combined to make up very slightly acid soft water.
This water, when it arrives on earth, flows by streaming and infiltrates the cracks to reach the groundwater tables and artesian tables that feed sources and wells. In both cases, this water dissolves and carries with it a part of the mineral salts it meets (limestone, magnesium, etc.); this is this last process, which causes its mineralisation. The more the water is mineralised, the harder it is !
The water hardness is expressed in degrees TH.
1 French degree TH corresponds to 10 mg of CO
3
Ca per litre of water.
from 0° to 5° TH very soft water
from 5° to 15° TH soft water
from 15° to 30° TH half-hard water
from 30° to 45° TH hard water
More than 45° TH very hard water
4.1. - The noxious effects of limestone
Any water contains traces of minerals, mainly limestone, magnesium and iron originating from the ground. The higher the content is, the harder the water is. These minerals reinforce the dirt catch to fabric fibres, and the eliminated one tends to be fastened again to them. Limestone reduces the efficiency of the washing product, makes the laundry rough, makes whites turn grey, fades colours and accelerates the laundry wear.
4.2. - The effects of too soft a water
Too soft a water also reduces the washing efficiency (reduction in mechanical action), causes foam overflows, leaks and accelerates the appliance ageing (the water is more aggressive).

LA3-ATLANTIS-002UK-04/04
4.3. - The water softening : a vital function
The system water contains soluble calcium hydrogen carbonate. Hot, the calcium hydrogen carbonate decomposes and gives insoluble calcium carbonate (fur). The water softening is, therefore, a vital function. This is the reason why all dishwashers are fitted, from the origin, with water softeners. Softening is, in fact, the substitution of calcium ions contained in the system water by sodium ions contained in the salt. To perform this substitution, the water is circulated in the heart of the softener that contains small balls of synthetic resin. Combined with sodium, this resin sets the limestone particles (calcium or magnesium) contained in the system water. To do so, the resin exchanges its sodium ions for the calcium ions. After a certain number of fillings, resins are more or less saturated with limestone and start becoming ineffective to soften the water. It is then necessary to regenerate them.
4.4. - The regeneration
To regenerate the resins, it is necessary to eliminate the limestone from them with sodium (salt).
This regeneration, automatic and "floating" on "all electronic" ATLANTIS dishwashers, is initiated by the board according to the adjustment performed on the putting into service and to the number of filling baths already performed.

4.5. - The pH (hydrogen potential)
Maybe, you have already remarked on labels of cleaning products or drinks the pH indication followed by a number. Maybe, you know that the pH is related to the acidity of a solution, sometimes verifiable by its taste. If you taste successively lemon juice, coffee and water, you will be able without any difficulty to rank these three liquids by level of acidity.

The pH paper is used for approximate, simple and rapid determination of the pH of a solution. This paper, which does not provide exact determination of a value of pH, rather gives an idea of the pH range of the solution, namely:
Acid for a pH smaller than 7
Neutral for a pH equal to 7
Basic or alkaline for a pH greater than 7
Water, mineralised or not (and, therefore, salt water) has a pH very close to 7.
A few acids
Vinegar (acetic acid)
Aspirin (acetylsalicylic acid)
Lemon juice (citric acid)
Coffee
Vitamin C (ascorbic acid)

A few bases

Alkaline pH is necessary for the washing bath to ensure maximum efficiency.
4.5.1. - Analysis of traces or deposits on dishes
Replacing a component supposed defective does not constitute the essentials of the maintenance of a dishwasher. A dishwasher, for which the consumer signals a bad wash result, cannot be repaired so easily. Actually, to solve this type of claim, it will always be necessary to precisely identify the nature of the trace or residue present on the piece of dishes. Only this precise identification can indicate us the probable cause at the origin of the defect. The matter is not to precisely measure the pH but simply to detect the origin of the white traces or of the residues. So, when the paper turns red we are in the presence of an acid solution (rinsing product for example), if it turns blue, then it is an alkaline solution (washing product).

5 - THE DETERGENTS
5.1. - The products
5.1.1. - The detergents
Contrary to many received ideas, all detergents are not identical. They contain specific ingredients. So each type of detergent has its own features and will be particularly suited to such or such type of wash or of dishes.
Detergent products are alkaline.
They have, therefore, a pH comprised between 9 and 11.
They are classified IRRITATING.
The powder
It is perfectly efficient under difficult wash conditions (very hard water or very dirty dishes) and is suitable for washing silver and decorated glasses.
The tabs
The dosage ease certainly explains the development of their market share. The dissolution time can vary from 10 seconds to over 10 minutes. When selecting a fast or short program, it's better to use powder.
The liquids
It is particularly more suitable for fragile dishes and respects the decoration.
5.1.2. - The rinsing product
It enables water to flow more rapidly and more completely from dishes, so preventing the formation of traces during drying. It neutralises alkaline residues of the detergent during the final rinse and favours the drying of dishes. Its acid pH is comprised between 1 and 3. It must be compatible with the detergent (it is preferable to keep the same product trademark).
5.1.3. - The regenerating salt
It is used to regularly regenerate the water softener resins. It protects the appliance and dishes from layers of sediment. Its pH is neutral and equal to 7.
5.1.4. - The "all-in-one" products
New products integrate in one and the same dose the 3 functions essential to the right operation of the dishwasher:
The wash function
The salt function
The rinse function
In cases of hard and very hard water (hardness greater than 35°TH), it is indispensable to use regenerating salt. Some manufacturers specify that the wash must be done at 50°C maximum under penalty of freeing too early the various actions of the product and altering the final result, or even damaging some pieces of dishes.
