How to Fix / Troubleshooting

Safety: Allow the machine to cool before working near the brew head.

  • Clean drip-stop: Remove the filter basket and inspect the drip-stop mechanism. Clean all moving parts with warm water and a brush.
  • Check spring action: Ensure the drip-stop moves freely and returns to the closed position when the carafe or cup is removed.
  • Descale brew path: Run a descaling cycle to remove scale that may prevent proper sealing.
  • Replace valve: If the drip-stop or internal brew valve seal is damaged or deformed, replace the valve assembly or seal kit.
