Ground too fine on a Dinamica Plus means water crosses the coffee too slowly; adjustment must be made only while grinding. 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. Fine particles, a restricted water path or an unprimed filter can make the brew pressure rise and slow delivery. Check whether hot water flows normally; normal water with slow coffee isolates grind and dose, while no water suggests the circuit. During active grinding, move the dial one step coarser, then prepare two or three coffees before judging the change. The message should clear and delivery become continuous; never turn several steps at once or adjust a stopped grinder.
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 the symptom may indicate
Checks in the right order
- Confirm the pattern
Fine particles, a restricted water path or an unprimed filter can make the brew pressure rise and slow delivery.
- 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.
- Apply the official check
During active grinding, move the dial one step coarser, then prepare two or three coffees before judging the change.
- Retest once
The message should clear and delivery become continuous; never turn several steps at once or adjust a stopped grinder.
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.
