Miele CM6 says Too much ground coffee

The CM6 Too much ground coffee message appears when the chute receives more than the permitted spoonful, preventing the brew unit closing correctly.

Manufacturer sources consulted

The CM6 Too much ground coffee message appears when the chute receives more than the permitted spoonful, preventing the brew unit closing correctly. Treat the display or symptom as a clue, not as proof that a pump, grinder or board must be replaced. Change one user-accessible condition at a time and let every shutdown finish. A heaped spoon, multiple spoonfuls or powder already left in the chute overloads the pre-ground chamber. This message follows use of the ground-coffee chute; it does not mean the bean grinder has produced too much coffee. Let the machine discard the excess, empty the grounds container, then add one level scoop only to the clean, dry chute and select ground coffee once. Prepare one cup. If the message returns with one level scoop and a clear chute, stop adding powder and ask Miele to inspect the brew path.

Models covered

Safety first

  • Keep water out of the bean hopper, grinder and electrical openings. Never reach inside a running grinder or force a hot, pressurised component.

What to distinguishThis message follows use of the ground-coffee chute; it does not mean the bean grinder has produced too much coffee.

Checks in the right order

  1. Confirm the pattern

    A heaped spoon, multiple spoonfuls or powder already left in the chute overloads the pre-ground chamber.

  2. Prepare safely

    Finish the automatic shutdown, unplug the machine and let hot surfaces cool. Remove only the tank, tray, brew group or cleaning accessory named by the manufacturer.

  3. Apply the official check

    Let the machine discard the excess, empty the grounds container, then add one level scoop only to the clean, dry chute and select ground coffee once.

  4. Retest once

    Prepare one cup. If the message returns with one level scoop and a clear chute, stop adding powder and ask Miele to inspect the brew path.

Stop and get qualified help when

  • Stop for a harsh grinder noise, repeated electrical error, uncontrolled leak, burning smell or a symptom that returns after the one official retest.

Next step

Repair, replace a part, or arrange a diagnosis?

Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.

Resolve it without buying anything

Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.

Replace only the confirmed part

If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.

This guide does not identify a replacement part. Do not order a generic component from the symptom alone.

Arrange a diagnosis before replacing the appliance

Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
