Strong plastic or chemical smell/taste from new or recently serviced machine

Safety: Ensure the unit is unplugged when handling internal parts.

• Initial cleaning: Wash the water reservoir, brew basket, and carafe with warm soapy water and rinse thoroughly.
• Flush cycles: Run 3–4 full reservoirs of clean water through the machine without coffee to flush internal components.
• Check hoses and gaskets: If parts were recently replaced, confirm that only food-safe, Moccamaster-approved silicone hoses and gaskets were used.
• Remove descaler residue: If you recently descaled, run additional plain water cycles to remove any remaining chemical taste.
• Replace suspect parts: If odor persists from a specific component (e.g., carafe lid gasket), replace that part with an OEM Moccamaster component.
