Brewer emits a plastic or chemical smell in the coffee.

Safety first: Do not ingest coffee that smells strongly of chemicals.

• Flush the system: Run multiple full reservoirs of plain water through the brewer without pods.
• Avoid harsh cleaners: Only use mild dish soap on removable parts and rinse thoroughly.
• Replace water filter: If your model uses a charcoal filter, replace it and soak per instructions before use.
• Persistent odor after thorough flushing: Contact Keurig support; internal plastic components may be defective.
