Coffee tastes weak or watery even when using the same amount of coffee as before.

Safety first: Unplug before any internal inspection.

• Check coffee and filter: Use medium grind coffee and ensure the filter is properly seated.
• Descale: Mineral buildup can affect temperature and flow. Run a full descaling cycle with vinegar and water, then rinse with clean water.
• Inspect spray head: Remove and clean the spray head to ensure all holes are open, promoting even saturation of the grounds.
• Evaluate temperature: If coffee is lukewarm right after brewing, the heater may not be reaching proper temperature, indicating a failing heating element or thermostat.
• Adjust ratio: If hardware is functioning, increase the coffee-to-water ratio slightly to compensate.
