Warning and Safety instructions This machine complies with all relevant local and national safety requirements. Incorrect use can, however, lead to personal injury and damage to property. Read the operating instructions carefully before starting to use this machine. This way you will avoid the risk of accidents and damage to the 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 care when handling liquid agents and additives. These may contain irritant or corrosive ingredients.
Warning and Safety instructions Only use low-foaming cleaning agents which have been approved by Miele. Foam can have an adverse effect on the cleaning process. Where a chemical additive is recommended on technical application grounds (e.g. a cleaning agent), this does not imply that the manufacturer of the machine takes liability for the effect of the chemical on the items being cleaned. Please be aware that changes in formulation, storage conditions etc.
Warning and Safety instructions Using accessories Only use genuine Miele accessories with this machine. Consult Miele on the type and application of such equipment. Disposing of your old machine Before disposing of your old machine first make it unusable. Disconnect from the mains, cut off the cable near the machine and any plug from the cable. For environmental and safety reasons ensure the machine is completely drained of any residual water and cleaning agent.
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 recycled.
Before using for the first time Before using for the first time please pay special attention to the following points. Detailed information on these points can be found in the relevant sections of these Operating Instructions. Water softener For machines without an integral water softener, a separate water softener is recommended in areas with a water hardness ü 3 °d (0.5 mmol/l). Only use cleaning and rinsing agents formulated for use in this type of machine.
Water softener Everything you need to know about the water softener The water needs to be softened to avoid calcium deposits building up on utensils and in the machine itself. To ensure a steady supply of soft water the water softener unit must always be: 1. correctly programmed and 2. the salt reservoir must be filled. If the water hardness level is below 3 °d - German scale (0.5 mmol/l) the reservoir does not need to be filled with reactivation salt.

Water softener Programming the water softener On machines with integral water softeners, programme the water softener as follows. ^ Press the [ control to switch the machine off. ^ Press and hold controls 4, { and §, and whilst doing so press [ to switch the machine on. P 19 will appear in the top display and the total water hardness level will appear in the bottom display in °d (25 in the display equates to 25°d or 4.5 mmol/l). ^ Press § or ° until the required hardness level shows in the bottom display.
Water softener Adding reactivation salt ,Only put reactivation salt in the salt dispenser. Inadvertently filling the salt reservoir with cleaning agent will damage the water softener. Before filling the salt reservoir make sure that you have selected reactivation salt to put in it! ^ Remove the basket from the machine. ^ Remove the basket carrier from the machine. ^ Unscrew the salt reservoir cap. ^ Fill the salt reservoir to the brim with fresh water (only necessary the first time of using).
Water softener Salt indicator light When the k indicator lights up in the display, the reactivation salt will need to be replenished. See "Adding reactivation salt". The water woftener runs automatically during a programme.
Crockery and baskets Preparing the load for washing, and loading the machine Preparing the load ^ Empty all containers and scrape residual food from crockery before loading into the machine. Inadequate pre-cleaning will block the filters and reduce the washing efficiency of the machine. Please note: ^ Load items so that water will come into contact with all surfaces. This ensures that they will be properly cleaned. Select baskets and inserts which are appropriate for the application.
Crockery and baskets Loading examples The dishwasher can be supplied with a standard range of baskets, or with baskets to suit your individual requirements. The diversity of inserts and baskets is so great that it is not possible to illustrate them all or give detailed instructions on their use here. For further information contact your supplier. The following illustrations show the most popular baskets with examples of loading plates, cups and cutlery.
Crockery and baskets Fitting the basket carrier The basket carrier is adjustable. The rails for the baskets can be fitted to the optional console, universal or feed-in table, so that the baskets can travel through the machine in a straight line or through it at a right angle. ^ Remove the basket carrier from its mounting. ^ Underneath the basket carrier you will find two screws at either end of one of the rails. The other rail is not removable. ^ Loosen the screws. ^ Remove the rail.

Cleaning agent can be dispensed in powder form using the filter basket, or in liquid form using an optional DOS module dispensing unit. Adding powder cleaning agents manually Do not add the powder cleaning agent until the water in the tank has reached the correct temperature.
