Coffee is too strong or bitter even with normal coffee amounts.

Safety first: Allow the unit to cool before handling the filter basket.

• Use correct filter: Ensure you are using the recommended filter type and not reusing paper filters.
• Adjust grind: On grind-and-brew models, choose a slightly coarser grind.
• Clean basket outlet: Wash the filter basket thoroughly and clear any coffee oils or residue from the outlet holes.
• Descale: Perform a descaling cycle to normalize flow rate.
