Possible Causes

Partially blocked flow path, Limescale in flow meter or tubing, Incorrect barcode reading, User stopping cycle early

How to Fix / Troubleshooting

Safety first: Let the machine cool before cleaning.

  • Allow full cycle: Do not press the start/stop button again during brewing, as this can prematurely end the cycle.
  • Clean T DISC holder and outlet: Rinse thoroughly to remove any blockages.
  • Clean barcode reader: Wipe the scanner window to ensure accurate volume programming.
  • Descale: Run a descaling cycle to restore full flow.
  • If underfill continues: The flow meter may be misreading and require replacement.
