Warning and Safety instructions
This machine conforms to current safety requirements. Inappropriate 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 future reference.
Correct usage
This machine is designed for commercial use and for specialised ap-
plications only, as described in these Operating Instructions. Using it for purposes other than those for which it was designed would be unauthorised and could cause harm.
The manufacturer cannot be held responsible for damage caused by improper use.
Please pay attention to the following notes, to maintain safe procedures.
The machine should be commissioned and then maintained only by
the Miele Service Department, an authorised Miele Service Dealer or other approved competent person.
Do not install the machine in an area where a danger of explosion
may be present, or sub-zero temperatures may occur.
Children and untrained personnel should not be allowed access to
the machine or its controls.
The electrical safety of this machine can only be guaranteed if
connected to a correctly installed earthing system on site. It is most important that this basic safety requirement is met and complies with local and national regulations. It should be checked by an expert if necessary.
The manufacturer cannot be held responsible for damage such as electric shock caused by missing or defective earthing.
A damaged machine is dangerous. Switch off at the mains im-
mediately and call an authorised Miele service dealer, or suitably competent engineer.
Any repair work may only be carried out by a suitably competent
person authorized by Miele. Repairs by unqualified persons could be dangerous for the user.
Take care when handling liquids such as detergents, wetting
agents, or neutralising agents. These may contain irritant or corrosive ingredients, acids or alkalis. On no account use any organic solvent, as there may be the danger of an explosion occurring. Follow the chemical manufacturer’s instructions and relevant safety procedures carefully. Wear protective gloves and goggles.
Avoid inhalation of powder cleaners. Irritant ingredients can
cause burning in the mouth and throat is swallowed, or inhibit breathing.
The water in the machine must not be used as drinking water.
5
Warning and Safety instructions
Do not sit or lean on the open door, or rest objects on it. This could
cause the machine to tip and be damaged.
Be careful when sorting items with sharp pointed ends and positioning them in the machine so that you do
not hurt yourself or create danger for other operators.
When using this machine at higher temperatures be especially careful
not to scald or burn yourself. Baskets and inserts must first cool down. Any water which may remain in containers will be very hot and must be emptied into the wash cabinet.
Do not touch the heating elements during or directly after the end of a
programme. You could burn yourself.
Never use an ordinary or a high pressure hose on or in the vicinity
of the machine.
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 withdrawing the mains fuse.
The following points should be observed to maintain standards, and avoid damage to the machine and the loads being cleaned.
Only use cleaning agents formulated for special processes and ap-
proved by Miele for use with this machine. Use of unsuitable cleaning agents could adversely affect the load and the machine.
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.
Where a chemical additive is recommended on technical applica-
tion grounds (for example with a cleaning agent), this does not imply that the manufacturer of the machine takes responsibility for the effect of the chemical on the material of 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.
Always follow the instructions of the chemical manufacturer when
using cleaning agents and special application chemicals. 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 only for operation with water and additive
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).
6
Warning and Safety instructions
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 are discussed with the Miele Application Technology specialists.
If the cleaning result is subject to these particularly stringent require-
ments (e.g. chemical analysis, specialised processes), a regular quality control test should be carried out by the user to ensure that required standards of cleanliness are being achieved.
Use special inserts in accordance with the instructions provided.
Empty any containers or utensils before arranging them in the ma-
chine.
Do not allow any remains of acids or solvents, 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).
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.
Follow both the installation instructions in this booklet, and also the
separate instructions with diagrams.
Accessories
The only accessories to be used with the special commercial machine must be those supplied or ap-
proved by MIELE for the specific application. Consult your dealer or the Miele Professional department for advice.
Disposal of an old machine
When disposing of an old machine first make it unusable. Disconnect, cut off the cable and any plug from the
cable. For environmental and safety reasons ensure the machine is completely drained of any residue 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. The simplest way to do this is to remove the locking pin (2 cross-slotted screws above the door). Make appropriate arrangements for the safe disposal of the machine.
For tank system machines ensure that any water is emptied out of the tank.
In countries where there are areas which may be subject to infestation by cockroaches or other vermin, pay particular attention to keeping the machine 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 machine guarantee.
The manufacturer cannot be held responsible for any damage caused through non-observance of these Warning and Safety instructions.

Description of the machine
This machine is a front-loading commercial dishwasher with very short batch times especially suitable for washing up in guest houses, cafés, fast food outlets, boarding houses, etc.
This machine is fitted with a water softener as standard.
8
Setting the water softener
To avoid the build-up of calcium deposits on crockery and in the dishwasher the water needs to be softened, if it is harder than 107 ppm.
To ensure a steady supply of soft water the water softener unit must be:
–correctly set, and
–the salt reservoir in the floor of the wash cabinet must be topped up with dishwasher reactivating salt as soon as the k light comes on.
The water softener must always be set to correspond with the water hardness the first time the machine is used.
Your local water authority will advise you on the water hardness in your area.
Setting the water softener
The hardness range is divided into 18 time settings and a zero position. The dishwasher is set at the factory for a water hardness setting "8", corresponding to 339 ppm.
If your water supply is harder or softer than this, then:
Use the touchpads on the control panel to change the setting, (see table).

Loading the dishwasher
Loading the dishwasher
Preparation
Empty loose remains from crockery prior to loading.
Notes
Load the crockery so that water will come into contact with all surfaces. This ensures that they will be properly cleaned.
Do not place crockery and cutlery inside other pieces where they may be concealed.
Hollow items such as cups, glasses, pots, etc, must be inverted in the basket, so the water can run off freely.
Deep-based items should be placed at such an angle that water runs off them freely.
Tall, narrow, hollow pieces should be placed in the centre of the basket to ensure good coverage of water.
Normally place cups and small pieces on the cup racks, but do not obsure them by larger items beneath. If necessary place bowls on the top rack and cups below them so that water reaches all pieces.
Do not cover the funnel to the spray arm in the middle of the upper basket.
The spray arms must not be blocked by items which are too high for the basket or which hang down in its path. If necessary, manually rotate the arm to test it.
Loading the upper basket
The upper basket accommodates small, light items such as cups, saucers, glasses, dessert bowls, small bowls and heat-resistant plasticware.
Loading the bottom basket
The bottom basket accommodates bigger items such as plates, serving platters,saucepans, bowls. Glasses may only be cleaned in the bottom basket if it is fitted with a special glassware insert.
Cutlery
Unsorted cutlery should be placed in the cutlery basket, handles pointing downwards.
For loading examples see next page.
