Flashing bean symbols after grinding on Avanza or Solo Perfect Milk point to bean delivery, grind setting or an interrupted brewing preparation rather than an empty water circuit. Observe whether the grinder actually turns, whether beans bridge above its inlet and whether dry ground coffee reaches the brew unit. Change the grind only while the grinder is running and one step at a time. A hard metallic noise or a grinder that remains stalled is a stop condition, not a reason to keep retrying. [object Object]

Safety first
- Keep water out of the bean hopper, grinder and electrical openings. Never force a brew unit, valve, grinder control or hot steam part.
What the symptom may indicate
Checks in the right order
- Confirm the model and signal
Confirm that the displayed or observed condition exactly matches “bean symbols flash after grinding” before changing anything.
- Prepare the appliance safely
Complete the normal shutdown, unplug the machine, let hot parts cool and empty the drip tray before removing user-accessible parts.
- Carry out the official user check
Add suitable dry beans, wipe only the dry hopper walls and tap the container lightly so beans feed toward the grinder, then grind once.
- Interpret one controlled retest
Reassemble every part in its documented position and run one short rinse or one beverage. A repeated signal after the stated check requires service rather than repeated resets.
Stop and get qualified help when
- Stop and contact the manufacturer if the same signal returns after one correct cycle, a grinder contains a foreign object, a hot-water leak appears or the machine trips power.
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.
