The manufacturer cannot be held liable for damage caused by improper or incorrect use of the machine.

should be trained regularly. Untrained personnel should not be allowed access to the machine or its controls.

The special inserts should only be

used for their specific application.

Technical safety

Before setting up the machine

check it for any externally visible damage. Under no circumstances should you use a damaged dishwasher. A damaged dishwasher may be dangerous.

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 present and regularly tested, and where there is any doubt the on-site wiring system should be inspected by a qualified electrician. The manufacturer cannot be held liable for damage or injury caused by the lack of or inadequacy of an effective earthing system (e.g. electric shock).

This machine is not intended for use

by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the machine by a person responsible for their safety.

Warning and safety instructions

Please follow the advice on

installation in these instructions and the separate Installation drawing.

Before connecting the machine to

the mains supply, make sure the rating on the data plate corresponds to the voltage and frequency of the on-site supply. Consult a qualified electrician if in any doubt.

A damaged machine is dangerous.

Switch off at the mains immediately and call the Miele Service Department or an authorised Miele Service Dealer.

Installation, maintenance and

repairs should only be carried out by a suitably qualified and competent person in accordance with local and national safety regulations. Repairs and other work by unqualified persons could be dangerous and the manufacturer will not be held liable.

Ensure current is not supplied to the machine until after installation, maintenance or repair work has been carried out.

If the connection cable is damaged,

the new cable must be fitted by a Miele approved service technician.

This machine should be

commissioned and then maintained by a Miele authorised and trained service technician or other suitably qualified and competent approved person. Repairs and other work by unqualified persons could be dangerous.

The machine must be disconnected

from the mains electricity supply before any maintenance or repair work is carried out. Do not reconnect it until the maintenance or repair work has been successfully completed.

For safety reasons, this machine

may only be used when it has been fully installed.

Never open the housing of the

machine. Tampering with electrical connections or components and mechanical parts is highly dangerous to the user and can cause operational faults.

Faulty components must only be

replaced by genuine Miele original parts. The manufacturer can only guarantee the safety of the appliance when Miele replacement parts are used.

Do not connect the machine to the

mains electricity supply by a multi-socket unit or an extension lead. These do not guarantee the required safety of the machine (e.g. danger of overheating).

In countries where there are areas

which may be subject to infestation 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 guarantee.

Warning and safety instructions

During installation, maintenance and

repair work, the machine must be disconnected from the mains electricity supply. It is only completely isolated from the electricity supply when:

the mains fuse is disconnected,

–

the screw-out fuse is removed (in

–

countries where this is applicable),

or it is switched off at the isolator.

–

Ensure that current is not supplied to the appliance until after maintenance or repair work has been carried out.

Correct use

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 instructions must be observed.

The water in the machine must not

be used as drinking water.

Only use detergents formulated for

commercial dishwashers. Do not use washing up liquid. The use of unsuitable cleaning agents could adversely affect the components of the machine, as well as items being cleaned.

Only use low-foaming cleaning

agents. Incorrect cleaning agents, as well as some types of soiling can cause a build-up of foam in the machine. Foam can have an adverse effect on the cleaning process.

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 such chemicals for the purpose and in the situation specifed, to the exclusion of other chemicals, to avoid such dangers as chemical reactions and material damage.

Warning and safety instructions

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 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).

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).

Never clean the machine or near

vicinity with a water hose or pressure washer.

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.

After any plumbing work, the water

pipework to the machine will need to be vented. If this is not done, the softener system could suffer damage.

While the appliance is under

guarantee, repairs should only be undertaken by a service technician authorised by the manufacturer. Otherwise the guarantee will be invalidated.

Do not sit or lean on the opened

door. This could cause the machine to 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, forks etc. should be placed in baskets with the pointed ends 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

or the heated surfaces on the wash cabinet floor 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.

Empty any containers or utensils

before arranging them in the machine.

Warning and safety instructions

Installation

This machine may only be used in

mobile installations such as ships, caravans, aircraft etc. if a risk assessment of the installation has been carried out by a suitably qualified engineer.

Do not install the machine in an area

where there is any danger of explosion or of freezing conditions.

Safety with children

This machine is not a toy! Keep

children away from it at all times and supervise them whilst you are using it. They will not understand the potential dangers posed by it. For instance, whilst playing they could inadvertently shut themselves inside it.

Older children should only be

allowed to use it unsupervised if its operation has been clearly explained to them and they are able to use it safely, recognising the dangers of misuse.

Accessories

Only use genuine Miele spare parts

and accessories with this machine. If spare parts or accessories from other manufacturers are used, this will invalidate the guarantee, and Miele cannot accept liability.

They must be suitable for the

purpose they are being used for. Consult Miele for advice.

Warning and safety instructions

Disposing of an old dishwasher

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 inoperable, so that children cannot accidentally shut themselves in. Then make appropriate arrangements for the safe disposal of the machine. For tank system machines ensure that any water is emptied out of the tank.

The manufacturer cannot be held liable for damage caused by non-compliance with these Warning and safety instructions.

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 offered for recycling.

Disposal of your old machine

Electrical and electronic appliances / machines 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 or machine. Please do not therefore dispose of your old machine or appliance 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.

Before using the machine for the first time, the following steps must be carrried out. Each step is described in more detail in the appropriate section further on in the booklet.

Before using for the first time

Only use detergents formulated for commercial dishwashers

Do not use washing up liquid or detergents formulated for domestic dishwashers.

Adding cleaning agent

Load the machine carefully

Arrange the load so that water will come into contact with all surfaces. Concealed surfaces will not be cleaned. The rinse and spray arms must not be blocked by any items.

Follow the cleaning agent manufacturer's recommendations on dosage.

The amount required will depend on the type of cleaning agent used and the programme selected.

Cleaning results may vary from brand to brand. If you are not satisfied with the results from one brand, try another quality glass cleaner for commercial dishwashers before contacting Miele for advice.

The filter combination in the floor of the wash cabinet and also the rinse and spray arms must be kept clean. It is therefore absolutely essential to check and clean them regularly.

Opening and closing the door

To open the door

Grasp the handle and open the door.

The door should only be opened during operation for emergencies, e.g. if articles are knocking together or if a programme fault is indicated in the display (see "Cancelling a programme").

Do not touch the inside of the

cabinet or the heated surfaces 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.

To close the door

Lift the door upwards and push until

it clicks shut.

Adding rinsing agent

Rinsing agent is necessary to ensure water does not cling and leave marks on items during the drying phase, and to help items dry faster after they have been washed.

Rinsing agent is poured into the storage container, and the amount set is dispensed automatically in the final rinse.

Preferably, use rinsing agent for commercial dishwashers that is specially formulated for glassware.

This dishwasher is fitted as standard with a built-in dispensing pump and rinsing agent container.

The container is located inside the right hand side of the service panel. It holds approx. 250 ml.

The rinsing agent level indicator is in the right-hand viewing window on the outside of the service panel.

Rinsing agent level indicator

Fill the rinsing agent container when the indicator on the right of the service panel shows there is insufficient rinsing agent.

Adding rinsing agent

Grasp the service panel handle and

open the panel.

^ Take the red cap off the filler spout.

^ Fill the container with rinsing agent,

using the funnel supplied.

^ Replace the red cap and close the

service panel.

^ Rinse out the funnel.

External rinsing agent container (optional extra)

A Miele service technician can retrospectively fit an external rinsing agent container to this dishwasher by means of a siphon tube.

The rinsing agent level indicator for the external container is on the control panel.

Place the rinsing agent container on

the floor next to the commercial dishwasher, or in a nearby cupboard or on a wall bracket.

The wall bracket is available from the Miele Spare Parts Department.
