If you prepare coffee every day, make these simple checks part of your routine.

• Empty the drip tray before it becomes full.
  
• Empty the coffee grounds container.
  
• Refill the water tank with fresh drinking water.
  
• Allow the automatic rinse programme to complete.
  
• Rinse the milk system after every milk drink.
  
• Wipe the coffee spouts and exterior with a soft damp cloth.
  

These simple tasks help prevent coffee residue, stale water and milk deposits from building up inside the machine.

Once each week, carry out a more thorough clean.

• Wash the drip tray and grounds container with warm soapy water.
  
• Clean the water tank.
  
• Remove and clean the brew unit if your model allows removal.
  
• Clean the coffee dispensing area.
  
• Wipe inside the service compartment.
  
• Clean the bean hopper lid and surrounding surfaces.
  

Keeping these areas clean helps ensure smooth operation and consistent coffee quality.

Milk residue is one of the most common causes of poor milk frothing and blocked pipework.

To keep your milk system working correctly:

• Run the automatic milk cleaning programme when prompted.
  
• Rinse the milk pipework after preparing milk drinks.
  
• Wash the milk flask or milk container regularly.
  
• Clean milk nozzles and connectors thoroughly.
  
• Use a suitable milk system cleaner when recommended.
  

Regular cleaning helps maintain smooth milk foam while reducing hygiene issues and unpleasant odours.

Your Miele coffee machine will periodically request a cleaning cycle.

When prompted:

• Use the recommended coffee machine cleaning tablets.
  
• Follow the on-screen instructions.
  
• Allow the cleaning programme to complete without interruption.
  
• Empty and rinse the drip tray afterwards if required.
  

Cleaning programmes remove coffee oils from the brewing system that cannot be reached through manual cleaning alone.

Limescale gradually forms inside every coffee machine, particularly in hard water areas.

When your Miele machine requests descaling:

• Use a suitable descaling product recommended for coffee machines.
  
• Start the descaling programme from the maintenance menu.
  
• Follow each step shown on the display.
  
• Do not switch the machine off during the process.
  

Regular descaling helps maintain brewing temperature, improves water flow and protects internal heating components.

If your machine uses a water filter, replacing it at the recommended interval helps reduce limescale while improving coffee flavour.

Benefits of replacing the filter regularly include:

• Better tasting coffee.
  
• Reduced limescale build-up.
  
• Improved water flow.
  
• Longer intervals between descaling.
  
• Better protection for internal components.
  

Always activate a new filter through the machine menu if your model requires it.

The grinder performs best when using quality coffee beans.

For reliable operation:

• Use dry roasted coffee beans.
  
• Avoid flavoured or sugar-coated beans.
  
• Avoid excessively oily beans where possible.
  
• Keep the bean hopper clean and dry.
  
• Adjust the grind setting gradually while the grinder is operating.
  

Good bean selection reduces grinder blockages and helps produce consistent coffee extraction.

Many common coffee machine faults can be avoided with regular care.

Routine maintenance helps prevent:

• Poor coffee flow.
  
• Weak coffee.
  
• Milk frothing problems.
  
• Water leaks.
  
• Blocked brewing systems.
  
• Limescale build-up.
  
• Grinder issues.
  
• Unnecessary fault messages.
  

Keeping your machine clean not only improves reliability but also ensures every cup tastes as it should.
