Do not use cracked/scratched carafe or one with loose handle. Do not drink directly from carafe (may be very hot). Return carafe if removed during brewing to prevent spills. Never open brew basket during use. Do not remove carafe during clean cycle. Ensure carafe is empty before cycles to avoid overflow. Do not brew without carafe in place.
