AEG Brew Circuit Blockage

No coffee comes out, but you can hear the grinder and pump running.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Clogged brew unit filter, Blocked coffee spout, Stuck ceramic valve, Severe limescale in hydraulic block

Safety: Unplug and allow to cool before opening.

Clean brew unit: Remove the brew group, rinse thoroughly, and clean the filter screen with a brush.
Clean spouts: Remove the coffee spout assembly and flush with hot water. Use a toothpick or fine brush to clear narrow channels.
Descale thoroughly: Run at least one full descaling cycle. If flow is still blocked, a second cycle may be needed.
Inspect ceramic valve: If accessible, check the ceramic diverter valve for scale and replace if seized.
