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 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. Do not use organic solvents as these could cause an explosion. Follow all relevant safety procedures carefully. Wear protective gloves and goggles. With all chemical agents, the manufacturer’s safety conditions must be observed.
Avoid inhalation of powder
cleaners. They can cause burning in the mouth and throat if swallowed, and can inhibit breathing.
The water in the machine must not
be used as drinking water.
Do not sit or lean on an open door.
The machine could tip up and be damaged, or cause an injury.
Be careful when sorting items with
sharp pointed ends and positioning them in the machine that you do not hurt yourself or create a danger for others. Sharp knives etc. should be placed in the baskets with the pointed end facing downwards.
When using this machine in the
higher temperature ranges be
especially careful not to scald or burn yourself when opening the door. Baskets and inserts must be allowed to cool down before they are unloaded. Any water remaining in containers could still be very hot. Empty them into the wash cabinet before taking them out.
Do not touch the heating elements
if you open the door during or directly after the end of a programme: you could burn yourself. They remain hot for some time after the end of the programme.
Never clean the machine or near
vicinity with a water hose or a high pressure hose.
Before any maintenance or repair
work is carried out, the machine must be disconnected from the mains supply by switching off at the mains isolator or withdrawing the mains fuse.
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 Miele approved cleaning
agents in this machine. Use of unsuitable cleaning agents could adversely affect the components of the machine as well as items being cleaned.
Foam can have an adverse effect
on the cleaning process. Only use low-foaming cleaning agents which have been approved by Miele. Some types of soiling can also cause foaming to occur.

Warning and Safety instructions
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 accepts liability for the effect of the chemical on the items being cleaned. Please be aware that changes in formulation, storage conditions etc. which may not be publicised by the chemical manufacturer, can have a negative effect on the cleaning result.
When using cleaning agents and
special application products, it is essential that the manufacturer’s instructions are followed. Only use such products for the purpose and in the situation specifed to avoid such dangers as chemical reactions and material damage.
The machine is designed for
operation with water and additive cleaning agents only. Organic solvents must not be used in this machine, as there is the danger under certain circumstances of fire or 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 agents, water quality etc., are discussed with the Miele Application Technology specialists.
If cleaning and rinsing results are
subject to particularly stringent requirements (e.g. chemical analysis, specialised industrial 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 hydrochloric acid or chloride solutions, to get into the wash cabinet. Similarly avoid any materials with a corrosive effect. The presence of solvents exceeding trace levels should not be present in soiling (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.
Please follow the advice on
installation in these instructions and the separate Installation Instructions.

Disposal 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. (Observe safety regulations and wear safety goggles and gloves). Make the door lock inoperative, so that children cannot accidentally shut themselves in. Then make appropriate arrangements for the safe disposal of the machine.
The manufacturer cannot be held liable for damage caused by non-compliance with these Warning and Safety instructions.

Water softener
The water needs to be softened to avoid calcium deposits building up on instruments and utensils and in the machine itself.
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
0.7 mmol/l (4 °d - German scale) the reservoir does not need to be filled with reactivation salt.)
The machine is set at the factory for a water hardness level of 3.4 mmol/l (19 °d).
If the water supply is harder or softer than this (including below 0.7 mmol/l or 4 °d) the factory setting will need to be changed following the instructions in "Setting the water softener". See chart on the next page for settings.
Your local water authority will advise you on the water hardness in your area.
For fluctuating levels (e.g. 1.4 - 3.1 mmol/l or 8 - 17 °d) set the water softener to the highest setting (in this example to 3.1 mmol/l or 17 °d).
Important The built-in water softener has settings from 0.2 - 10.8 mmol/l or 1 °d - 60 °d.
