Possible Causes

Grind set too coarse on Miele grinder, worn grinder burrs, low coffee dose setting in menu, brew unit pressure valve leaking

How to Fix / Troubleshooting

User adjustments:

  • Adjust the grind setting on the Miele grinder one step finer (while the grinder is running) and test again.
  • Increase the coffee strength or quantity in the user settings menu.
  • Use fresh, high-quality beans; avoid oily or very light roasts that can affect extraction.

Technical checks:

  • Inspect the grinder burrs for wear; if edges are rounded, replace the burr set or complete grinder.
  • Clean the brew unit thoroughly, including the filter screen, to restore proper pressure.
  • If coffee pucks are very wet and loose, check the brew unit pressure valve and seals; replace if leaking.
