Warning and Safety instructions This machine complies with all relevant local and national safety requirements. Incorrect use can lead to personal injury and damage to property. To avoid the risk of accidents and damage to the machine please read these instructions carefully before starting to use this machine. Keep these instructions in a safe place for reference, and pass them on to any future user.
Warning and Safety instructions Personnel operating the machine should be trained regularly. Untrained personnel should not be allowed access to the machine or its controls. This machine is not a toy. Do not allow children to play in or around it or to operate it. There is a danger that they could injure themselves or get into the machine and lock themselves in. Take great care when handling liquid agents and additives. These may contain irritant or corrosive ingredients.
Warning and Safety instructions The following points should be observed to assist in maintaining quality standards, to protect users, and to avoid damage to the machine and items being cleaned. Only use cleaning agents designed for use in this type of machine. Using unsuitable cleaning agents could adversely affect the machine, as well as items being cleaned. Only use low-foaming cleaning agents. Incorrect cleaning agents, as well as some types of soiling, can cause a build-up of foam in the drum.
Warning and Safety instructions Do not allow any remains of acids or solvents, and in particular hydrochloric acid or chloride solutions, to get into the wash cabinet. Similarly avoid any materials with a corrosive effect. The presence in compounds of any solvents should be minimal (especially those in hazard class A1). To avoid any corrosion damage, ensure that solutions or steam containing hydrochloric acid do not come into contact with the steel outer casing of the machine.
Caring for the environment Disposal of the packing material The transport and protective packing has been selected from materials which are environmentally friendly for disposal and can normally be recycled. Ensure that any plastic wrappings, bags etc. are disposed of safely and kept out of the reach of babies and young children. Danger of suffocation! Rather than just throwing these materials away, please ensure that they are offered for recycling.
Before using for the first time Before using the machine for the first time you require: – approx. 2 litres of water, – approx. 2 kg dishwasher reactivation salt, – dishwasher detergent, – rinse aid. Every dishwasher is tested at the factory. There will be residual water in the machine from this test. It is not an indication that it has been used previously.
Before using for the first time To open the door Child safety lock The yellow key for the child safety lock is on one of the spikes at the front of the upper basket. Remove the key before switching on the dishwasher and keep it in a safe place away from the dishwasher. ^ Press the release catch inside the door grip and pull forward. If the door is opened during operation all functions are automatically interrupted.
Before using for the first time Water softener In order to achieve good cleaning results, the dishwasher needs to operate with soft water. Hard water results in the build-up of calcium deposits on crockery and in the dishwasher. Mains water with a hardness level higher than 0.7 mmol/l (4° d – German scale) needs to be softened. This takes place automatically in the integrated water softener. – The water softener requires dishwasher reactivation salt.
Before using for the first time Programming the water hardness level ^ Switch the dishwasher off with the On/Off button I-0. ^ Press the +c and h/f buttons in and whilst holding them in switch the dishwasher on with the On/Off button I-0. Then release these buttons. The "Main wash/Rinses" l indicator light will come on and the "Salt" k indicator light will flash. ^ Use the programme selector buttons %$ to select the value that corresponds to your water hardness level (see chart on the right).
Before using for the first time Value displayed °d German scale mmol/l °f 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36-70 0.2 0.4 0.5 0.7 0.9 1.1 1.3 1.4 1.6 1.8 2.0 2.2 2.3 2.5 2.7 2.9 3.1 3.2 3.4 3.6 3.8 4.0 4.1 4.3 4.5 4.7 4.9 5.0 5.2 5.4 5.6 5.8 5.9 6.1 6.3 6.5-12.
Before using for the first time Filling the salt reservoir In order to achieve good cleaning results, the dishwasher needs to operate with soft water. Hard water results in the build-up of calcium deposits on crockery and in the dishwasher. Mains water with a hardness level higher than 0.7 mmol/l (4° d – German scale) needs to be softened. This takes place automatically in the integrated softener unit. The softener unit requires dishwasher salt.
Before using for the first time As the salt reservoir is filled, displaced water will overflow. ^ Clean any excess salt from around the reservoir opening and then screw the cap on again firmly. ^ Run the COLD I programme immediately to remove any traces of salt water from the cabinet. Salt indicator The salt indicator light comes on to notify you that the reservoir is empty. Note If the water in your area is very soft and constantly lower than 0.7 mmol (4 °d) you do not need to add salt to the reservoir.
Before using for the first time Rinse aid Adding rinse aid Rinse aid is necessary to ensure water does not cling and leave marks on crockery during the drying phase and helps crockery dry faster after it has been washed. Rinse aid is poured into the storage reservoir and the amount set is dispensed automatically. ,Inadvertently filling the rinse aid reservoir with powder or liquid detergent always causes serious damage to the reservoir. Only pour rinse aid formulated for dishwashers into the reservoir.
Before using for the first time Rinse aid indicator When the light comes on the reservoir contains sufficient rinse aid for 2 - 3 programmes only. ^ Add rinse aid only until it is visible on the surface of the filter in the opening. The rinse aid reservoir holds approx. 130 ml. ^ Add rinse aid in plenty of time. ^ Close the flap firmly so that it clicks into place. Otherwise water would enter the rinse aid reservoir during a programme. ^ Wipe up any spilled rinse aid.
Before using for the first time Setting the rinse aid dosage The dosage selector has settings from 1-6. It is set to "3" (3 ml) at the factory. Approx. 3 ml of rinse aid are then used per programme. This is a recommended setting. If spots appear on crockery and glassware: ^ Use a higher setting. If clouding or smearing appears on crockery and glassware: ^ Use a lower setting.
Loading the machine Preparing the load ^ Remove coarse residues and empty all containers before loading into the machine. Please note ^ Load items so that water will come into contact with all surfaces. This ensures that they will be properly cleaned. ^ Do not place items to be cleaned inside other pieces where they may be concealed. ^ Hollow items such as cups, glasses, pots etc. should be inverted and placed in the correct inserts. The water must be able to access them unhindered.
Loading the machine Items not suitable for dishwashers: – Wooden cutlery and crockery or items with wooden parts: these may discolour and fade. The glue used in these items is not dishwasher-proof and wooden handles may come loose after being washed in a dishwasher. – Craft items, antiques, valuable vases and decorative glassware are also not suitable for dishwashers. – Plastic items which are not heat resistant. The high temperatures in the dishwasher may cause them to melt or lose shape.
Loading the machine Upper basket Hinged cup rack For small, lightweight, delicate items such as cups, saucers, glasses, dessert bowls, etc. Shallow pans or casserole dishes can also be placed in the upper basket. To make room for tall items, raise the rack upwards. Long items such as soup ladles, mixing spoons and long knives should be placed lying down across the front of the upper basket.
Loading the machine Adjusting the upper basket In order to gain more space for taller pieces of crockery in the bottom or upper basket, the upper basket can be adjusted on three levels with 2 cm between each level. The upper basket can also be set at an angle with one side high and the other side low. Ensure, however, that the basket can be inserted smoothly into the cabinet. It is better to adjust the basket before loading it. ^ Pull out the upper basket.
Loading the machine Lower basket Height limitation For larger and heavier items such as plates, serving platters, saucepans, bowls, etc. Glasses and small items such as saucers can also be placed in the lower basket. Do not place thin, delicate glassware in the lower basket. The stay at the front of the upper basket determines the maximum height permissible for items placed in the lower basket to ensure they do not impede the movement of the middle spray arm.
Loading the machine Lower basket inserts A variety of inserts for washing crockery in the lower basket are available to order. To remove an insert ^ Pull upwards by the handle as shown. To refit it ^ Fit the insert into the lower basket with the hooks going under the long cross piece as illustrated. ^ Press down on the handle until the insert is securely held in position.
Operation Detergent ,Only use detergents formulated for dishwashers. Do not use washing up liquid. Do not use tablet detergent as the short programme durations will not allow the tablets to dissolve properly. ^ Use conventional powder detergent. Refer to the dosing instructions given by the manufacturer on the packaging. If you wish to use liquid detergent, you will need to purchase a DOS G 60 dispensing module. (See "Programming special functions, Dispensing system settings").
Operation Adding detergent ,Avoid inhalation of powder detergents and do not ingest dishwasher detergent. Dishwasher detergents contain irritant or corrosive ingredients. They can cause burning in the nose, mouth and throat if swallowed, or inhibit breathing. Consult a doctor immediately if detergent has been swallowed or inhaled. Keep detergent and other cleaning agents out of the reach of children at all times. Keep children away from the dishwasher when the door is open.
Operation Switching on Starting a programme ^ Make sure the spray arms are not obstructed. ^ Please refer to the programme chart before selecting a programme. ^ Close the door. ^ Then use the programme selector buttons %$ to select the programme you wish to use. ^ Open the stopcock, if it is closed. ^ Press the On/Off button I-0.
