What should I do if the MIELE CVA 7845 displays fault code F1, F2, F74, F77, F80, F82, or F225-F354?
These codes indicate an internal fault.
• For F1, F2, F80, F82, F353, F354: Switch the coffee machine off. Wait for approximately 1 hour before switching the machine back on again.
• For F74, F77, F225, F226, F235, F353, F354: Switch the coffee machine off. Wait for approximately 2 minutes before switching the machine back on again.
If the error message appears again after restarting, contact Miele Technical Service.
What should I do if the MIELE CVA 7845 displays “F73” or “Check the brew unit”?
This means the brew unit cannot be positioned correctly or is soiled.
1. Check if you can remove the brew unit. If you can, rinse it under running water.
2. Push the coffee ejector of the brew unit into the correct position (the flap inside should be down).
3. Replace the water container and close the door. Do not insert the brew unit yet. Switch the machine on to initialize the motor.
4. When “Insert the brew unit” appears on the display, put the brew unit back in.
5. If you cannot remove the brew unit, switch the machine off. Wait approximately 2 minutes before switching it back on.
Why did my MIELE CVA 7845 stop a manual maintenance program prematurely?
This usually happens because the water container has not been filled and inserted correctly, or the wrong fill level was used.
• Check that you have selected the correct mark. The symbols on the water container indicate the amount of water required: for Descale Appliance and for Clean the milk pipework.
• Ensure the container is pushed in until it engages.
• Fill the water container up to the relevant mark and restart the process.
Why doesn’t the MIELE CVA 7845 display respond or why does it turn off suddenly?
Display remains dark when turned on:
• The On/Off button () was not held long enough. Tap and hold it for at least 3 seconds.
• The plug is not properly inserted into the electrical socket.
• The fuse has tripped. Check the fuse and contact an electrician or Technical Service if needed.
Coffee machine turns off suddenly:
• The factory-set switch-off time (20 minutes) or a programmed time has been reached. You can change this in “Settings – Timer”.
• The plug may not be properly plugged in.
Sensor buttons do not respond:
There may be an internal fault. Disconnect the coffee machine from the power supply by removing the plug or switching off the circuit breaker, then reconnect it.
Why can’t I remove or re-insert the brew unit on my MIELE CVA 7845?
The brew unit drive is not positioned correctly. To reset it:
1. If the brew unit is out, ensure its handle is in the correct start position.
2. Close the appliance door.
3. Switch the coffee machine off.
4. Wait approximately 1 minute before switching the coffee machine back on.
5. This will initialize the brew unit drive and move it into the correct start position, allowing you to insert or remove the brew unit.
Why is coffee dispensing repeatedly interrupted on my MIELE CVA 7845?
This is not a fault. The brew unit has not detected enough ground coffee. This can happen with certain coffee types, especially if the grinder is set too fine and the amount of coffee is set to minimum.
• Confirm the message “Fill the bean container” with OK.
• If it happens with all coffee types, set the grinder to a coarser setting and select a larger amount of coffee in the drink parameters.
• If it happens only with specific drinks, check the “Amount of coffee” parameter for that drink and select a larger amount. You may also need a coarser grinder setting.
Why is the coffee from my MIELE CVA 7845 not hot enough?
There are several possible reasons for this:
• The cup has not been pre-heated. The smaller the cup and thicker its walls, the more important it is to pre-heat it. Pre-heat the cup with hot water.
• The brewing temperature is set too low. Go to the drink’s Parameters and set a higher brewing temperature.
• The filters in the brew unit are blocked. Remove the brew unit, clean it by hand, and run the “Degrease the brew unit” maintenance program.
Why does the coffee taste weak, or why are the grounds sludgy?
This is likely because an insufficient amount of coffee beans are getting into the grinder, resulting in less coffee being brewed.
• Dark roast coffee beans are often oily and can cling to the walls of the bean containers, hindering flow. Clean the bean containers more often if using oily beans.
• Very large or different-sized beans can get wedged and form “bean bridges”. Try pulling the bean containers out slightly and giving them a shake.
• If the issue persists, try using a different type of coffee.
Why is the milk froth consistency unsatisfactory from my MIELE CVA 7845?
There are two common causes for poor milk froth:
• The milk temperature is too high. Good milk froth can only be achieved with cold milk (below 50°F/10°C). Check the temperature of the milk in the milk flask.
• The milk pipework is blocked and/or the milk valve is soiled. Remove and clean the milk valve thoroughly.
What are the installation dimensions for the MIELE CVA 7845 coffee system?
When installing the MIELE CVA 7845 in a tall cabinet, maintain a minimum installation height of 33 7/16″ (850 mm).
The cabinet niche dimensions are:
• Niche Height: 17 15/16″ (455.5 mm)
• Niche Width: 22 1/8″ (562 mm)
• Niche Depth: at least 23 5/8″ (600 mm)
The overall appliance dimensions are:

• Width: 23 7/16″ (595 mm)
• Depth: 17 1/2″ (444 mm) without door, 24 15/16″ (≥ 633 mm) with door open
How do I build the MIELE CVA 7845 into the cabinet?
You will need a TX 20 screwdriver for installation.
1. Connect the machine to the water and electricity supplies before building it in.
2. Remove the red silicone shipping plug from the screw hole on the appliance door frame by pulling it firmly.
3. Push the coffee machine all the way into the niche, ensuring the electrical and water connections do not get trapped.
4. Check that the machine is sitting centrally and is level.
5. Open the appliance door. You will see screw holes on the side frames.
6. Secure the coffee machine to the side walls of the cabinet using the two supplied TX20 (25 mm) screws. Tighten both screws by hand.
How can I remove the door opening limiters on the MIELE CVA 7845?
The door hinges are equipped with limiters that restrict the opening angle to approx. 120°. Removing them increases the angle to approx. 170°, making it easier to access components like the bean containers.
Warning: Before removing, make sure there is sufficient space and that the door will not hit an adjacent wall.
To remove the limiters, carefully prize them out from the hinges using a tool like a screwdriver.
