Possible Causes

Scale buildup in flow path, Flow sensor misreading volume, Incorrect cup size selection, Clogged pod or filter

How to Fix / Troubleshooting

Safety first: Unplug before descaling or cleaning.

  • Verify settings: Confirm the selected cup size on the display matches your desired volume.
  • Descale: Run a full descaling cycle to clear scale from the flow sensor and internal tubing.
  • Clean pod holder: Ensure the pod holder and needles are free of clogs that could restrict flow.
  • Test with water only: Brew without a pod and measure the output. If still low, the flow sensor or pump may be failing.
