LIMPIEZA-STANDBY-PARPADEAN
Melitta LIMPIEZA-STANDBY-PARPADEAN on Solo: brewing unit unlocked
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On the Melitta Solo, if the cleaning symbol and the standby (or ready) symbol flash alternately, the brewing unit is probably not locked correctly. Unlock it and lock it again; if it continues, remove it, refit it and lock it once more.

Unlock and lock again
- Who:
- you, no tools.
- How:
- reach the brewing unit as the manual shows, unlock it and lock it again fully, without removing it.
- Result that matters:
- the symbols no longer flashing alternately.
- If they stop flashing:
- it only needed locking properly.
- If they keep flashing:
- remove the unit and refit it.
- Evidence to keep:
- a photo of the engaged lock.

Remove, refit and lock
- Who:
- you, with the machine switched off.
- How:
- remove the brewing unit, check there is no residue in the housing, reinsert it straight and lock it.
- Result that matters:
- a properly seated unit and the warning off.
- If the warning goes:
- it was not seated properly.
- If the unit will not go in:
- reposition the drive.
- Evidence to keep:
- a photo of the empty housing.

Reposition the drive
- Who:
- you.
- How:
- check the tank has water and the drip tray is in place; switch the machine off and on and hold the coffee and steam buttons together for more than 2 seconds so the drive repositions; then insert and lock the unit.
- Result that matters:
- the unit going in and locking.
- If it goes in and the warning clears:
- the drive was out of position.
- If it still will not go in or the warning returns:
- do not force it; contact Melitta service.
- Evidence to keep:
- a note of what the machine was doing before the warning.

What it means
Melitta explains that the cleaning symbol flashing alternately with the standby symbol, or with the ready symbol depending on the version, means the brewing unit is possibly not locked correctly. The brewing unit is the removable part where the coffee is pressed. Melitta asks you to unlock and relock it and, if it continues, remove, reinsert and lock it again. If the unit will not go back in, the drive may be out of position, and Melitta gives a sequence to reposition it. The warning does not prove the unit is broken.
