Water leaks from the front of the machine around the brew head or portafilter during brewing.

Safety: Hot water can burn. Allow the machine to cool before touching the brew head.

• Check portafilter/basket: Ensure it is properly locked into place and not overfilled with coffee.
• Clean gasket area: Use a brush to clean coffee oils and grounds from the brew head and gasket groove.
• Inspect gasket: Look for cracks, flattening, or hardening of the rubber gasket. If worn, it must be replaced.
• Replace gasket: Pry out the old gasket with a blunt tool, clean the groove, and press in a new Zwilling-compatible brew head gasket. Test for leaks.
