Possible Causes

Clogged needles, Scale buildup in lines, Faulty flow meter, User-selected strong/bold mode reducing volume

How to Fix / Troubleshooting

Safety first: Unplug before cleaning needles.

  • Clean needles and K-Cup holder: Use a paper clip and rinse thoroughly.
  • Descale: Run a full descale to restore normal flow.
  • Check settings: Ensure you are not in a special mode (e.g., strong) that may alter volume.
  • Measure output: Brew into a measuring cup to confirm actual volume vs. selected size.
  • If volume remains low after cleaning: The flow meter may be misreading and require replacement.
