Coffee tastes weak or watery even when using normal amounts of coffee.

Safety first: Unplug before cleaning internal surfaces.

• Adjust coffee grind and dose: Use a medium grind suitable for drip coffee and increase the amount of coffee slightly if needed.
• Disable 1–4 cup mode: Ensure you are not accidentally using a special mode that changes brew strength on a full pot.
• Clean showerhead: Remove the brew basket and clean the showerhead or water outlet holes with a soft brush to ensure even water distribution.
• Descale: Run a descale cycle to restore proper brew temperature and flow.
• Check temperature: If coffee is lukewarm right after brewing, the heater may not be reaching proper temperature, requiring professional service.
