Coffee Machine Coffee Grounds In Cup

Finding coffee grounds in your cup usually means the filter basket, brew group, or shower screen is letting ground coffee through.

⚡ TL;DR — Quick Answer

Clean the brew group and shower screen, check the paper filter for tears, and make sure the grind setting is not too fine.

Understanding Coffee Grounds In Cup

Grounds in the cup are almost always a mechanical bypass: a torn or misaligned filter, an overfilled basket, or a worn seal in the brew group. Very fine grind can also push particles through the filter. The problem worsens when the brew group is not cleaned regularly.

Universal Troubleshooting Steps

These steps work across all major brands:

  1. Empty and inspect the filter basket: replace it if torn or deformed.
  2. Clean the shower screen and brew group under running water, removing old coffee residue.
  3. Check the grind size; if it is very fine, coarsen it one step.
  4. Do not overfill the basket; use the included scoop and level the coffee.

Remove it according to the manual and rinse with lukewarm water, no soap on the moving parts, then dry and refit.

The basket may be overfilled or the filter is the wrong size. Use the correct size and level the coffee bed.

Only if it is visibly worn or clogged beyond cleaning. Soaking in descaling solution usually restores it.
