Plug the power cord into a grounded 120V AC outlet.

WARNING! Ensure the brewer is on a stable, heat-resistant surface. Keep away from water sources and do not immerse in liquid.

First-Time Use

Prime the brewing system before first use.

Ensure the water reservoir is filled and the carafe is in place on the warming plate.

Care & Cleaning

Weekly: Wipe exterior with a damp cloth. Clean the drip tray and pod holder assembly. Remove the brew basket and rinse under warm water.
Monthly: Descale the brewer when the DESCALE light comes on (see next section).

CAUTION! Unplug brewer before cleaning. Do not use abrasive cleaners or scouring pads. Never immerse the brewer base, cord, or plug in water.

Descaling

Place a large carafe or container (at least 12 cups) on the warming plate.
Press POWER, then press and hold the 6oz and 12oz buttons simultaneously for 3 seconds to start the descale cycle.
The brewer will run the solution through in intervals. It may take 30-45 minutes. Empty the container as needed.
When the cycle is complete, discard the vinegar solution. Rinse the water reservoir thoroughly.
Refill the reservoir with fresh water. Run multiple 12-oz brew cycles (without a K-Cup) until the vinegar smell is gone.
