Kenmore Residue from Manufacturing or Internal Plastics

Brewed coffee has a plastic or chemical taste, especially on a newer Kenmore coffee maker.

Possible Causes

Residue in water reservoir and tubing, New plastic components off-gassing, Use of harsh cleaners not fully rinsed

Safety first: Unplug when not running a cycle.

Initial cleaning: Before first use and if taste persists, run 2–3 full reservoirs of water-only cycles.
Vinegar rinse: Run a cycle with a 1:1 vinegar-water mix, then follow with 2–3 water-only cycles to flush.
Avoid scented cleaners: Do not use scented detergents or soaps inside the reservoir or brew path.
Use filtered water: Using filtered water can reduce off-flavors and improve taste.
