8
Warning and Safety instructions
When running a disinfecting programme in accordance with
official regulations on the control of epidemics, the programme must not be interrupted once it has been started (see Cancelling a programme in an emergency).
The standard of disinfection in the disinfection programmes must be
routinely confirmed by the user. The process should be regularly monitored using thermo-electrical, chemical or bio-indicators, and this should be fully documented.
Disinfection programmes must not be interrupted as this can have a
limiting effect on the disinfection result. If interruption is unavoidable, however, the complete programme must be repeated.
For thermal disinfection, use temperatures and temperature
holding times to achieve the required infection prophylaxis in accordance with current health and safety regulations.
Only use Miele approved cleaning agents in this machine. Using
unsuitable cleaning agents could adversely affect the components of the machine, as well as items being cleaned.
For pre-treatment and/or cleaning, only use low-foaming cleaning and
disinfecting agents which have been approved by Miele. Foam can have an adverse effect on the disinfection and 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 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 chemicals, it is
essential that the manufacturer’s instructions are followed. Only use such chemicals for the purpose and in the situation specified, to the exclusion of other chemicals, 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 agent, water quality etc. are discussed with the Miele Application Technology specialists.
9
Warning and Safety instructions
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.
Hollow instruments must be thoroughly cleaned, internally and externally.
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 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.
Please follow the advice on installation in these instructions
and the separate Installation Instructions.
Using accessories
Only use genuine Miele accessories with this machine.
Consult Miele on the type and application of such equipment.
Only use Miele mobile units, baskets and inserts in this
machine. Using accessories made by other manufacturers, or making modifications to Miele accessories can result in unsatisfactory cleaning and disinfecting results, for which Miele cannot be held liable. Any resultant damage would also invalidate the machine guarantee.
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.
10
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.
Disposal of your old appliance
Electrical and electronic appliances often contain materials which, if handled or disposed of incorrectly, could be potentially hazardous to human health and to the environment. They are, however, essential for the correct functioning of your appliance. Please do not therefore dispose of it with your household waste.
Please dispose of it at your local community waste collection / recycling centre and ensure that it presents no danger to children while being stored for disposal.
It should be unplugged or disconnected from the mains electricity supply by a competent person. Any plug must be rendered useless and the cable cut off directly behind it to prevent misuse. See the "Warning and Safety" section of this booklet for further details.

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.

Filling the salt reservoir
Please only use special coarse grained reactivation salt with granules of approx. 1-4 mm. Do not use other types of salt, e.g. table salt, agricultural or gritting salt. These could contain components which are insoluble in water which could result in damage to the water softener. If in doubt consult your Miele Professional Department.
The salt reservoir holds approx. 2.5 kg of salt.
,Inadvertently filling the salt reservoir with cleaning agent will damage the water softener.
Before filling the salt reservoir make sure that you have picked up the right packet of reactivation salt.
^Remove the bottom basket from the machine.
^Unscrew the salt reservoir cap.
Before filling the salt reservoir with reactivation 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).
^Wipe any residual salt off the screw threads on the socket.
^Screw the cap on firmly.
^Immediately after this: Run the PRE-RINSE programme D to remove any traces of salt from the cabinet.
Important: If after starting the PRE-RINSE programme D the machine does not start for a few minutes this is not a fault. The water softener is being reactivated.
