Used coffee grounds are very wet and sludgy in the filter or brew group.

Safety first: Allow the machine to finish brewing and cool before handling grounds.

• Clean filters: Thoroughly clean the Kenwood filter basket, brew screen, and any metal filters.
• Descale: Run a descaling cycle to restore proper water flow and pressure.
• Check grind: For espresso or bean-to-cup, avoid extremely fine grinds that can cause channeling and sludge.
