Possible Causes

Brew group seal failure, Cracked brew chamber, Loose hose on coffee outlet, Blocked coffee spout causing backflow

How to Fix / Troubleshooting

Safety first: Unplug the machine and allow it to cool. Hot water may be present inside.

  • Check coffee spout: Clean the Kenwood coffee outlet thoroughly with a brush and run a rinse cycle to clear blockages.
  • Inspect brew group (bean-to-cup): Remove and rinse the brew group. Check the large O-ring seals for damage or flattening.
  • Monitor drip tray: If large amounts of clear water collect in the tray during brewing, an internal leak or bypass is likely.
  • Service needed: Internal seals or hoses may need replacement, which requires disassembly by a technician.
