Zwilling Brew Group Compression / Drainage Problem

Used coffee pucks are very wet and sludgy, or the grounds container fills with loose wet grounds.

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

Brew group not compressing grounds properly, Blocked brew group drainage path, Worn brew piston seals

Safety: Unplug the machine before removing the brew group.

Clean brew group: Remove the brew group and rinse thoroughly. Pay attention to the piston and screens.
Lubricate moving parts: Apply food-safe silicone grease to the brew group rails and piston seals.
Check drainage holes: Ensure the brew group drainage channels and holes are not blocked with coffee residue.
Inspect seals: If piston seals are worn or cracked, replace them or the entire brew group assembly.
