programme, you could burn yourself. They remain hot for a while after the end of a programme.
Never clean the machine or close vicinity with a water hose or a high
pressure hose.
Before any maintenance or repair work is undertaken, the machine must be disconnected from the mains
supply by switching off at the mains isolator or switching off the mains fuse.
The following notes should help to avoid material damage.
Only use detergents formulated for special processes and
approved by Miele for use with this machine. Use of unsuitable detergents could adversely affect the components of the machine as well as items being cleaned.
For pre-treatment and / or cleaning only use low-foaming detergents
and disinfecting agents which have been approved by Miele. Foam can have an adverse effect on the disinfection and cleaning process.
7
Warning and safety instructions
Where a chemical additive is recommended on technical grounds
(e.g. with a cleaning agent), this does not imply that the manufacturer of the machine takes responsibility for the compatibility with the items being cleaned.
Please be aware that changes in formulation, storage conditions etc., which may not be publicised by the chemical producer, can have a negative effect on the cleaning result.
When using cleaning agents and specialised products, it is essential
that the manufacturer’s instructions are followed. Only use the product for the application described by the manufacturer, to avoid any material damage or the occurrence of strong chemical reactions.
The machine is designed only for operation with water and cleaning agents. Organic solvents must not be
used in the machine, as there is the danger under certain circumstances of explosion. (Although this is not the case with all organic solvents, other problems could arise with their use, for example damage to rubber and synthetic materials).
In critical applications where very stringent requirements have to be
met, it is strongly recommended that all the relevant factors for the process, such as cleaning agent, quality of water, etc. are discussed with the Miele Application Technology specialists.
If the cleaning result is subject to particularly stringent requirements
(e.g. chemical analysis, specialised processes, etc.), a regular quality control test must be carried out by the user to ensure that required standards of cleanliness are being achieved.
The special inserts should only be used for their specific application.
Empty any containers or utensils before arranging them in the machine.
Do not allow any remains of acids or solvents, and in particular hydro-
chloric acid or chloride solutions to access 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).
Ensure that solutions or steam containing acid salts do not come into
contact with the steel outer casing of the machine, to avoid any corrosion damage.
Please follow the advice on installation in these instructions and in the
separate Installation Instructions.
In countries where there are areas which may be subject to infesta-
tion by cockroaches or other vermin, pay particular attention to keeping the appliance and its surroundings in a clean condition at all times. Any damage which may be caused by cockroaches or other vermin will not be covered by the appliance guarantee.

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 section of the Operating Instructions.
Setting the water softener.
The water softener unit must be set to deal with the water hardness level in your area.
The salt reservoir must also first be filled with water and then with dishwasher reactivation salt.
Important
Filling the salt reservoir with detergent by mistake will cause serious damage to the water softener.
Please check every time before refilling that the package contains dishwasher reactivation salt.
Adding rinse aid.
Inadvertently filling the reservoir for rinse aid with powder or liquid detergent, or washing up liquid, will cause serious damage to the reservoir.
Only use designated cleaning agents for special applications.
Do not use detergents formulated for use in domestic dishwashers.
Loading the crockery correctly.
Arrange the load so that water will come into contact with all the surfaces. This ensures that they will be properly cleaned.
The spray arms must not be blocked by any items.
Adding the correct amount of cleaning agent.
Follow the detergent manufacturer’s recommendations. Using less than advised can adversely affect cleaning results.
The amount dispensed will depend on the type of detergent used and the programme selected.
Read the notes on dosage given in the programme chart.
Cleaning results may vary from brand to brand. If you are not satisfied with the results from one brand, try another quality brand before contacting the Customer Service Department for advice.
The filter combination in the base of the wash cabinet and the spray arms must be kept clean.
Regular checking and cleaning are essential.
11
Opening and closing the door
Electric door lock
The machine is equipped with an electric door lock.
The door can only be opened when:
the machine is connected electrically
the main switch I-0 is on.
To open the door a
Press the door button in fully and at the same time pull open the door.
Do not touch the heating elements if you open the door during or directly after the end of a programme. The heating elements remain hot for some time after the end of a programme.
To close the door
Lift the door upwards until it clicks into position. Do not push in the door release button as you do so.

The door remains locked until the end of the programme, when it can be opened again.
Cancelling a programme
If a programme has to be cancelled in extreme cases, e.g. when articles in the machine jostle against each other or the programme is interrupted with a fault indication, the door must be opened (deliberate intervention):
Turn the programme selector switch to f (the programme is cancelled after approx. 2 secs.).
Important: Further procedures are described in the section “Switching on and off” under “Cancelling a programme”.
Opening the door with the emergency release
The emergency release should only be used when the door cannot be opened normally (e.g. power failure).
Turn the programme selector switch to f.
Switch off the machine (I-0 switch). Pull down the emergency release behind the door outer panel.
12
Water softener
To avoid the build-up of calcium deposits on items being cleaned and in the machine the water needs to be softened.
To ensure a steady supply of soft water the water softener unit must always be:
1.correctly set (programmed) and
2.the salt reservoir must be filled.
(If the water hardness level is below 70 mg/l (4°d) the water does not need to be softened.)
The machine is set at the factory for a water hardness level of 340 mg/l
(19 °d).
If the water supply is harder or softer than this (including below 70 mg/l or 4°d) the factory setting will need to be changed following the instructions in the section “Setting the water softener”. For settings, see chart on the next page.
Your local water authority will advise you on the water hardness in your area.
For fluctuating levels (e.g. 140 - 310 mg/l or 8 - 17°d) set the water softener to the highest setting (in this example to 310 mg/l or 17°d).
Important
The built-in water softener has settings from 20 mg/l to 1080 mg/l or 1°d - 60°d.
For future servicing it is useful to make a note of your water hardness level.
Enter details of your water hardness level here: °d / mg/l

15
Water softener
Filling the salt reservoir
Please only use specialised reactivation salt, if possible coarse grained reactivation salt, with granules of approximately 1- 4 mm. Under no circumstances must other salts be used, e.g. table salt, or gritting salt. These could contain components which are insoluble in water which could result in damage to the water softener.
The salt reservoir holds about 2.5 kg of salt.
Inadvertently filling the salt reservoir with dishwasher detergent always causes serious damage to the water softener.
Make sure that you have picked up the right packet of reactivation salt before filling the salt reservoir.
Remove the bottom basket.
Unscrew the salt reservoir cap.
Before filling the salt reservoir with salt for the first time, fill it with approx. 2.5 litres of water.
Place the funnel provided in place.
Fill carefully with salt, (as it is filled displaced water will run out).
Clean salt from the screw threads of the socket.
Screw the cap on firmly.
Run the “COLD” programme D immediately to remove any traces of salt water from the cabinet.
Important:
If, after switching on, the D (COLD) programme start is delayed for a few minutes this is not a fault. The water softener is being reactivated.
16
Water softener
Salt indicator
When the salt reservoir is empty the k indicator light c comes on. The reservoir should be refilled with dishwasher salt for reactivation.
The reactivation programme runs automatically during a programme.
The indicator light k b on the programme sequence display lights up during this process.
