How to Fix / Troubleshooting

Safety first: Allow the unit to cool before descaling.

Standardize operation:

  • Select a brew size and do not change settings once brewing starts.

Clean and descale:

  • Clean the brew basket and drip stop.
  • Run a full descale cycle to normalize flow.

If volume remains erratic, the flow sensor or control board may be faulty and require service.
