To avoid the risk of accidents or damage to the appliance it is essential to read these instructions before it is installed and used for the first time.

Disposal of the packing material

The packaging is designed to protect the machine from damage during transportation. The packaging materials used are selected from materials which are environmentally friendly for disposal and should be recycled.

Recycling the packaging reduces the use of raw materials in the manufacturing process and also reduces the amount of waste in landfill sites.

Disposing of your old machine

Electrical and electronic machines often contain valuable materials. They also 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 machine. Please do not therefore dispose of it with your household waste.

This coffee machine complies with current safety requirements. Improper use can, however, present a risk of both personal injury and material damage.

To avoid the risk of accidents and damage to the machine, please read these instructions carefully before using it for the first time.

They contain important notes on installation, safety, use and maintenance.

Miele cannot be held liable for damage caused by non-compliance with these instructions.

Keep these instructions in a safe place and pass them on to any future owner.

Correct application

This coffee machine is intended for use in domestic households and similar working and residential environments.

Examples of a working or residential environment include

– shops, offices and other working environments,

– small businesses, showrooms etc.,

- where the coffee machine is being used by customers in hotels, motels, bed and breakfast and other similar establishments.

This coffee machine is not intended for outdoor use.

It must only be used as a domestic appliance to make espresso, cappuccino, latte macchiato etc. Any other use is not permitted.

This coffee machine can only be used by people with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, if they are supervised whilst using it, or have been shown how to use it in a safe way and recognise and understand the consequences of incorrect operation.

Safety with children

⚠️ Aution! Danger of burning and scalding on the dispensing spouts.

Children's skin is far more sensitive to high temperatures than that of adults.

Ensure children do not touch hot surfaces of the coffee machine or place parts of their body under the dispensing spouts.

▶ Install the coffee machine where it is out of the reach of children.
Children under 8 years of age must be kept away from the machine unless they are constantly supervised.
Children 8 years and older may only use the coffee machine unsupervised if they have been shown how to use it safely and recognise and understand the consequences of incorrect operation.
▶ Please supervise children in the vicinity of the coffee machine and do not allow them to play with it.
Children must not be allowed to clean the coffee machine unsupervised.
Remember that coffee and espresso are not suitable drinks for children.
▶ Danger of suffocation.

Packaging, e.g. plastic wrappings, must be kept out of the reach of babies and children. Whilst playing, they could become entangled in packaging or pull it over their head and suffocate.

Technical safety

▶ Installation and repairs may only be carried out by a Miele authorised service technician. Installation, repairs and other work by unqualified persons can cause considerable danger to users.
A damaged coffee machine could be dangerous. Before building in the machine, check it for any externally visible damage. Do not use a damaged machine.
To avoid the risk of damage to the machine, make sure the connection data (voltage and frequency) on the data plate corresponds to the household supply, before connecting the machine to the mains supply. Consult a qualified electrician if in any doubt.
The electrical safety of this coffee machine can only be guaranteed when correctly earthed. It is essential that this standard safety requirement is met. If in any doubt please have the electrical installation tested by a qualified electrician.
▶ Reliable and safe operation of the coffee machine can only be guaranteed if it is connected to the mains electrical supply.
Do not connect the machine to the mains electricity supply by a multi-socket adapter or an extension lead. These are a fire hazard and do not guarantee the required safety of the appliance.
The coffee machine must not be used in a non-stationary location (e.g. on a ship).
For safety reasons, this machine may only be used when it has been built in.
If the coffee machine is to be built in above another appliance, there must be a full-width, closed shelf between them.
▶ Only use the coffee machine in rooms where the ambient temperature is between +10 °C and +38 °C.

▶ Do not cover or block the ventilation gaps.

This would prevent adequate ventilation. Condensation can damage the coffee machine or the furniture housing unit.

▶ Ensure that there is sufficient ventilation around the coffee machine. The ventilation gaps in the furniture housing unit and the gap between the top of the housing unit and the ceiling must be at least 200 cm ^2 . Otherwise condensation can build up and damage the machine or the housing unit.

If the coffee machine is built-in behind a kitchen furniture door, it may only be used with the furniture door open. This will prevent the formation of heat and humidity and subsequent damage to the machine and/or furniture unit. Do not close the furniture door while the coffee machine is in use. Ensure the coffee machine has cooled down completely before closing the furniture door.

▶ Repairs may only be carried out by a Miele authorised service technician. Repairs by unqualified persons can cause considerable danger to the user.

The coffee machine must be disconnected from the electricity supply during repair work.

While the machine is under guarantee, repairs should only be undertaken by a Miele authorised service technician. Otherwise the guarantee is invalidated.

▶ Faulty components must only be replaced by genuine Miele Original spare parts. The manufacturer can only guarantee the safety of the machine when Miele replacement parts are used.

▶ Never open the outer casing of the machine. Tampering with electrical connections or components and mechanical parts is highly dangerous to the user and can cause operational faults or electric shock.

Only use genuine original Miele accessories with this machine. Using spare parts or accessories from other manufacturers will invalidate the guarantee, and Miele cannot accept liability.

Plumbed in water connection

Do not connect the coffee machine to a hot water supply.
The stopcock must be easily accessible after the coffee machine has been built in.
The protective sleeve of the water inlet hose must not be damaged or become kinked.
The integrated water protection system offers protection from water damage, provided the following conditions are met:
- the coffee machine is correctly installed, connected to the electricity supply and plumbed in.
- if a fault is identified, the machine must be repaired immediately.
- the stopcock is turned off when the machine is not used for a longer period of time (e.g during holidays).

Correct use

⚠️ The spouts present a danger of burning or scalding. The liquids and steam dispensed are very hot.

▶ Please note:

  • Keep well away from the area underneath the spouts when hot liquids and steam are being dispensed.
  • Do not touch hot components.
  • Hot liquid or steam could spatter from the spouts. Ensure that the central spout is clean and fitted correctly.
  • Water in the drip tray can also be very hot. Take care when emptying it.

⚠️ Never look directly at the lighting or use optical instruments to look at it.

▶ Please note the following regarding water:

  • When using the water container: Only use cold, fresh tap water to fill the water container. Warm or hot water or other liquids can damage the coffee machine.
  • Change the water every day to prevent a build-up of bacteria. If the machine is connected to the mains water supply: Empty the water container once a day.
  • Do not use mineral water. Mineral water will cause serious limescale deposits to build up in your machine and damage it.
  • Do not use water from a reverse osmosis unit in this machine. This would damage it.

▶ Only fill the bean container with roasted espresso/coffee beans. Do not fill the bean container with coffee beans which have been treated with additives or with ground coffee.

Do not fill the bean container with any type of liquid.

Do not use green (unroasted) coffee beans or mixtures of coffee beans which contain green coffee beans. Green coffee beans are very hard and still contain a certain amount of residual moisture. These can damage the coffee machine grinder as soon as grinding begins.
Do not use coffee beans which have been treated with caramel, sugar or other substances including sugary liquids. Sugar will damage the coffee machine.
▶ Only add ground coffee or the Miele cleaning tablets for degreasing the brew unit to the ground coffee chute.
Do not use any caramelised ready ground coffee. The sugar in the coffee will stick to and block the brew unit of the coffee machine. The cleaning tablets for degreasing the brew unit will not remove this type of deposit.
▶ Only use milk without additives. Additives in milk usually contain sugar and this will stick to the milk pipework.
If using dairy milk make sure that it has been pasteurised.
Do not place any alcohol mixtures which are alight underneath the central spout. The flames could ignite plastic components and cause them to melt.
Do not swing from or hang anything on the machine front when it is open as this could damage the hinges on the coffee machine.
The central spout connector cap is lubricated with silicone grease. Take care not to get this on your clothes when removing or replacing the containers or other components.
The machine must not be used for cleaning objects.

Cleaning and care

The coffee machine must be disconnected from the electricity supply before cleaning or maintenance.
Clean the coffee machine and the milk flask thoroughly before using for the first time (see "Cleaning and care").
All parts of the milk system need to be cleaned thoroughly and regularly. Milk contains bacteria which proliferate rapidly with inadequate cleaning.
Do not use a steam cleaner to clean this machine. Steam could reach electrical components and cause a short circuit.
▶ Descale the coffee machine regularly depending on the water hardness level in your area. Descale the machine more frequently in areas with very hard water. Miele cannot be held liable for damage arising from insufficient descaling, the use of incorrect descaling agent or the use of descaling agent which is not of the appropriate concentration.
▶ Degrease the brew unit regularly with Miele cleaning tablets. Depending on the natural oil content of the coffee used, the brew unit can become blocked quite quickly.
▶ Used coffee grounds should be disposed of with the organic rubbish or on the compost heap. Do not empty them down the sink, as they could block it.

For machines with stainless steel surfaces:

Do not use sticky notes, transparent adhesive tape, masking tape or other types of adhesive on stainless steel surfaces. These damage the surface, causing it to lose its dirt repellent protective coating.
The finish on stainless steel surfaces is susceptible to scratching. Even magnets can cause scratching.

Change the water every day to nt a build-up of bacteria.

If the coffee machine is plumbed into the mains drinking water supply, the water container will fill automatically as soon as the machine is switched on.

The inlet device in the lid ensures that the water is taken in slowly.

If the coffee machine has not been used to make any drinks for a long time there will be water left in the inlet hose.

This can impair the taste of the coffee.

Discard the first full container of water.

You can also fill the container manually if you are not using the plumbed in water supply (see "Settings - Mains water connection")

If filling the water container manually: Only use fresh, cold tap water.

Hot or warm water or other liquids can damage the coffee machine.

Do not use mineral water. Mineral water will cause serious limescale deposits to build up in your machine and damage it.

You can cancel the process at any time by:

■ duching OK or □.

Making coffee with ground coffee

To make coffee using ready ground coffee, add a portion of ground coffee to the ground coffee chute.

This gives you the option of making a

cup of decaffeinated coffee, for example, even though the coffee bean container is filled with roasted coffee beans.

The coffee machine will recognise automatically that ready ground coffee has been added to the ground coffee chute.

Only one portion of coffee or espresso can be made at a time when using ground coffee.

Adding ground coffee

Do not add more than one level scoop of ground coffee to the coffee chute. If too much is added, the brew unit will not be able to process the coffee.

The coffee machine will use all the ground coffee which has been added to the chute to make the next coffee.

Coffee the way you like it

To set the coffee machine up for the type of coffee you are using, you can

  • change the grinder setting,
  • change the amount of coffee,
  • set the brewing temperature, or
  • pre-brew the ground coffee.

Grinder setting

When the beans are ground correctly, the coffee or espresso will flow evenly into the cup with a good crema.

The crema should have an even nut-brown colour.

The grinder setting you select will be used for all coffee drinks.

There are various ways to tell whether the coffee grinder is set correctly.

The coffee has been too coarsely ground if:

  • Espresso or coffee flows into the cup too quickly.
  • The crema is very pale and uneven.

Set a finer grinder setting.

The coffee has been too finely ground if:

- Espresso or coffee only trickles into the cup.

- The crema is dark brown.

Set a coarser grinder setting.

To avoid damaging the grinder, please note the following: Only adjust the grinder one setting at a time. Grind the coffee beans again if you want to adjust the grinder to the next setting.

■ Open the font of the coffee machine.

MIELE CVA 6405 - Grinder setting - 1

■ Rsh the slide control one setting to the left (for finer grinding) or one setting to the right (for coarser grinding).
- Close the front.
■ Make one cup of coffee.

Adjust the grinder setting again.

The altered grinder setting will not be used until after the second coffee has been dispensed.

Displaying and changing the parameters of a drink

■ ðuch Ⓞ.
■ Select the drink you want and touch OK.

The current settings for the amount of coffee, brewing temperature and pre-brewing will be displayed for this drink.

Amount of coffee

The coffee machine can grind and brew 6-14 g of coffee beans per cup. The greater the quantity, the stronger the coffee.

There are various ways to tell whether the amount of coffee is set correctly.

The amount of coffee is too low if:

  • Espresso or coffee flows into the cup too quickly.
    – The crema is very pale and uneven.
  • The espresso or coffee lacks body.

Increase the amount of coffee so that more ground coffee is brewed.

The amount of coffee is too high if:

  • Espresso or coffee only trickles into the cup.
  • The crema is dark brown.
  • The espresso or coffee tastes bitter.

Decrease the amount of coffee so that less ground coffee is brewed.

■ Select Amount of coffee and then touch OK.
■ Use the arrow sensors ∧∨ to change the amount. Touch OK.

The setting is now saved.

Tip: If the coffee is too strong for you or it tastes bitter, try a different type of bean.

Brewing temperature

The ideal brewing temperature will depend on

– the type of coffee being used,
- whether an espresso or a coffee is being made, and
– the altitude of the region.

If the coffee machine is located at more than 2000 metres above sea level, the brewing temperature needs to be set lower due to the change in pressure. This is because the boiling point for water at a high altitude above sea level is lower than the boiling point for water at sea level.

Tip: Not all types of coffee can withstand high temperatures. Certain types are too delicate - the crema on top would not be as good and the taste would be impaired.

The coffee machine has five brewing temperatures.

■ Select Brew temperature and then touch OK.
■ Select the required temperature and touch OK.

The setting is now saved.

Pre-brewing the coffee

When the pre-brewing function is switched on, the freshly ground coffee is first moistened with a little hot water. Then the remaining water is forced through the moistened coffee at high pressure. This helps release the flavour of the coffee.

You can set pre-brewing for a short or long length of time, or deselect "Pre-brewing" altogether.

The machine is supplied with the "Pre-brewing" function switched off.

■ Õuch the arrow sensors ∧∨ until Pre-brewing is highlighted. Touch OK.

The pre-brewing option which is currently selected will be marked with a tick √.

■ Õuch the arrow sensors ∧∨ until the setting you want is highlighted. Touch OK.

The setting is now saved.

The flavour of the coffee produced depends not just on the type of coffee used, but also on the amount of water used. You can programme the amount of water to suit the size of your cups and the type of coffee you are using.

For coffee drinks that use milk, in addition to the amount of espresso or coffee, you can also set the amount of milk or milk froth to be dispensed. You can also set the portion sizes for hot milk and milk froth separately.

Each type of drink has a maximum portion size that can be programmed into the machine. The coffee machine halts preparation of the coffee once this portion size has been reached. The maximum possible portion size for this type of drink is then saved in the machine.

The changed portion size is always saved in the current Profile. The name of the current profile appears in the top left-hand side of the display.

There are two ways to start programming the portion amount:

  • Either by touching the drink sensor when you are making a coffee, or
  • By selecting Portion size in the Parameters Ⓞ menu.

Tip: You can cancel the portion size programming as long as Stop is visible in the display.

If the water container becomes empty whilst making a drink, the machine will stop programming the portion size. The portion size will not be saved.

Changing the portion size while making a drink

You can change and save the portion size for Espresso 📋, Coffee 📋, Cappuccino 📋 and Latte macchiato 📋 while making these drinks.

■ Place cup under the central spout.
■ Õuch the sensor for the drink you want until Change appears in the display.

Problems when heating up or frothing milk

Problem Cause and remedy
The milk sputters when it is dispensed. Hissing noises can be heard when milk is being heated up or frothed. Although the milk should be frothed, only hot milk is dispensed from the central spout.The milk temperature is too high. Good milk froth can only be achieved when cold milk (< 10 °C) is used.■ Check the temperature in the milk flask.
The milk flask has not been fitted correctly and so air as well as milk is being sucked in.■ Rush the milk flask in until it clicks into position.
The central spout is not fitted correctly.■ Check whether the central spout has been assembled correctly.
The milk pipework in the milk flask lid is dirty.■ Dismantle the milk flask lid and clean it with the cleaning brush (see "Cleaning and care – Milk flask").■ Cleanthe central spout and the milk valve with the cleaning brush (see "Central spout" and "Maintenance of the milk valve").
The angled connector is blocked and must be replaced.■ Replace the angled connector (see "Replacing the angled connector").
Fill and insert milk flask appears in the display even though the milk flask has been filled and inserted in the machine.The milk flask lid could be dirty and this has prevented the sensing function from working properly.■ Clean the milk flask lid and the milk flask thoroughly. Dismantle the lid and clean it with the cleaning brush supplied (see "Cleaning and care – Milk flask and lid").

Replacing the angled connector

If instead of being frothed the milk is only being heated up, check the following first:

  • Is the milk in the milk flask cold (< 10 °C)?
  • Have the central spout and the milk flask lid been cleaned carefully?
  • Is the central spout correctly fitted?

If after checking the above, milk still cannot be frothed, replace the angled connector as follows:

■ Canect the stainless steel hose to the stopcock.

Use the stainless steel hose supplied with the machine. Old or used hoses must not be connected to the coffee machine.

■ Ensure that it is screwed into position correctly.
■ Turn on the stopcock slowly and check for leaks. Correct the position of the seal and union, if necessary.

Proceed with building in the coffee machine (see "Installation").

All electrical work should be carried out by a suitably qualified and competent person only, in strict accordance with current national and local safety regulations (BS 7671 in the UK). Installation, repairs and other work by unqualified persons could be dangerous. The manufacturer cannot be held liable for unauthorised work.

The voltage and frequency are given on the data plate located inside the machine. Please ensure these match the household mains supply. This data must correspond in order to avoid damage to the machine. The fuse rating is quoted on the plug.

The coffee machine is supplied with a mains cable with moulded plug for connection to a 50 Hz, 220-240 V mains supply.

The fuse rating must be at least 13 A.

Connection should be made via a fused plug and suitable switched socket which is easily accessible after installation. If the mains socket is not accessible after the appliance has been built in, a separator for each terminal must be present. There must be an all-pole contact gap of at least 3 mm in the switch (including switch, fuses and relays according to EN 60335).

Do not connect the machine to an inverter such as those used with an autonomous energy source e.g. solar power. When switched on, peak loads in the system can cause the safety switch off mechanism to be triggered. This can damage the electronic unit.

The coffee machine must not be used with so-called energy saving devices either. These reduce the amount of energy supplied to the machine causing it to overheat.

Building-in and combination options

The machine is designed to be built into a tall unit.

It can also be combined with other Miele built-in appliances. If the coffee machine is to be built in above another appliance, there must be a full-width, closed shelf between them (except when it is combined with a suitable Miele built-in plate or food warming drawer).

Ventilation

Condensate can damage the coffee machine or the housing unit.

The ventilation gaps given must be observed.

Do not cover or block the ventilation gaps.

Dust the ventilation gaps regularly.

Steam which is created when water is heated up can condense on the interior and the inside of the front of the coffee machine.

When installing the coffee machine ensure that there is sufficient ventilation at the rear of the machine to allow steam and heated air to escape without hindrance.

The housing unit should be configured as follows:

MIELE CVA 6405 - Ventilation - 1

text_image ≥200cm² 500mm ② 40mm ①

- Air intake ① occurs via the plinth at the bottom of the machine and the air escapes at the top ② at the rear of the housing unit.

  • A ventilation gap of at least 40 mm depth must be allowed for behind the machine for air to circulate.
  • The ventilation cross-sections in the plinth, housing unit and below the room ceiling must amount to at least 200 ~cm^2 to ensure that air can circulate without hindrance.

Top ventilation gap

The ventilation gap at the top of the machine can be constructed in different ways:

② in between the housing unit and the ceiling
③ through a suspended ceiling.

Building in the coffee machine

Before installation make sure that there is no power supply to the machine. This also applies should it ever need to be taken out of its housing unit.

The machine may only be operated when built-in and in an ambient temperature range between +10 °C to +38 °C.

You will need two Allen keys (size 3 and 5) for installing the machine.

To align the machine front with the furniture front ensure that there is a sealing strip provided all the way around the building-in niche or around the coffee machine.

If the housing unit niche is not fitted with a sealing strip you should fit a Miele sealing strip to the machine before installing it. This is fitted from the back of the machine.

The sealing strip is available to order from Miele.

Tip: It is useful to have somewhere at the height of the niche to place the machine on. This makes electrical connection and connection to the plumbed in water supply easier.

■ Using the large allen key, unscrew all four feet out by about 2 mm.

The feet can be unscrewed by up to approx. 10 mm.

■ Plumb the machine into the mains water supply (see "Plumbed in water connection").

■ Connect the machine to the electrical supply.

Take care not to damage the electrical connection or the plumbing connection when pushing the coffee machine into the niche.

■ Rsh the coffee machine all the way into the niche until you feel a resistance.

■ Check the height of the coffee machine to make sure that it is sitting centrally in the niche and that it is level. If this is not the case, realign the machine using the four feet.

Four M5 socket screws are supplied for aligning and securing the machine in its niche.

■ Open the font of the machine and loosely fit the screws at either side.
■ Carefully turn the lower socket screws to centre the machine in the niche.
■ tighten both upper socket screws by hand to secure the machine in the unit. Do not overtighten them.

Adjusting the hinges

If the machine front becomes difficult to open or close after installation, you can adjust the hinges to realign it (TX 20):
