Coffee is very weak or watery even at maximum strength setting; pucks are thin and fall apart easily.

Safety first: Unplug the machine before adjusting internal components; grind adjustment can be done while running.

Step-by-step checks:

• Adjust grind finer: While the grinder is running during a coffee cycle, turn the grind knob one step finer. Test and repeat as needed, allowing a few cups between adjustments.
• Increase strength: Set the coffee strength or aroma setting to a higher level in the menu.
• Use fresh beans: Replace old or stale beans with fresh, medium-roast beans.
• Service brew group: Remove, clean, and lubricate the brew group. Inspect seals and O-rings; if they are flattened or cracked, have them replaced.

When to call a technician: If coffee remains weak despite adjustments, the grinder burrs or brew group seals may be worn and should be replaced by a service professional.
