Coffee tastes weak even when using normal amounts of coffee.

Safety first: Use caution when handling hot components.

• Adjust coffee and grind: Use a medium grind and increase the coffee dose slightly to see if taste improves.
• Check brew strength setting: If your Wolf Gourmet model has a strength selector, set it to a stronger setting.
• Clean showerhead: Remove the brew basket and inspect the water outlet/showerhead above it. Wipe away any scale or coffee residue with a damp cloth or soft brush.
• Descale: Run a descaling cycle to restore proper brew temperature and flow characteristics.
• If coffee remains consistently weak: The heating block may not be reaching optimal temperature due to a failing thermostat or sensor, requiring professional diagnosis.
