Miele CVA4080 milk not foaming, just hot milk
Hi Aenne. This sounds like a blockage.
Milk needs the introduction of air in order to foam/froth milk. Automatic espresso machines usually use a Venturi system which is a basic syphon method of introducing air into the steam milk mixture. This comes in the shape of a small manual valve with a fine hole in it. My recommendation would be to clean or change the complete foaming/frothing system manually. Generally there is a small airvalve/expander baffle with a fine hole that has most likely become blocked. You will need to make sure this is clear and that you can blow through it. Also ensure the foamer head is completely clear and runs some milk cleaning solution through
it. This should solve the issue....
If there is no manual air valve, then maybe the machine uses an automatic milk pump to inject the air which may be failing. This may require a technician to replace. I doubt that this will be the case. I hope this helps.

I have a Miele CV 4080. The waste that is discharged from the brewing unit to the waste container has become a runny mess recently, it used to discharge a solid pellet.
Have you changed your type of coffee beans or grind setting recently? First of all I would recommend removing and cleaning the brew unit thoroughly (as per cleaning instructions) to eliminate any cleaning issue here...
This is sounds like the flush valve is not working correctly. The flush valve ensures that all unused liquid in tubes is flushed into the driptray and that all solid coffee (dry pellet) goes from the brew chamber into the waste container. At the end of the coffee cycle when the pump stops running, the piston in the brew unit usually moves one last cycle and squeezes the coffee pellet in the chamber one last time and the flush valve operates so that all waste liquid is flushed from the coffee pellet to the drip tray. If your pellet is wet, then this final flush is not working. There may be a blockage in your flush tube or the flush valve may be blocked. These usually block up if you don't run a cleaning tablet through the machine regularly.
My advice is to remove the driptray grill and check that the tubes running into the tray from the brew unit are not accidentally squeezed closed or blocked. Good luck.

Miele coffee system cva 615.
More then likely there is nothing wrong with the water seal but simply the tank was not placed properly over the seal and water was bypassed to the reservoir. If a significant amount of water sits in the reservoir the "Water System Fault" trouble will appear and stop operation. The easiest way to remove the water from the reservoir is with an inexpensive ($5) siphon tool available at any auto parts store. Once the water has been removed and you can operate the machine and it goes through the "Warming" sequence you will receive a "Air in water System" alert. Follow the simple directions in the manual to correct this trouble and your system is back to normal. I have heard people have been charged by technicians up to $600 to fix this trouble and told the seal had to be replaced. Just take care when placing a full water tank back into place and enjoy : )
