Oxo 12 Cup Coffee Maker

Place the OXO 12-Cup on a level surface. Fill the glass water tank (up to 60oz for a full 12-cup brew) with cold, filtered water — the glass tank makes water level easy to read at a glance. Plug in.

For a full carafe: use the full-size flat-bottom brew basket. Insert a flat-bottom basket paper filter. Add medium-ground coffee (approximately 6–8g per 5oz cup desired). Select your brew size on the front control and press brew.

For single-cup or small batches: insert the included single-cup basket insert. Use a Kalita Wave 155 paper filter (sold separately). Brew directly into a mug or travel cup. The single-cup mode adjusts temperature and flow for smaller volumes.

Auto-on programming: set the desired start time via the display for automatic morning brewing. Pre-load water and coffee the night before.

Full Carafe vs. Single Cup

The dual-basket design is the OXO 12-Cup's key differentiator — the same machine brews a full 60oz pot or a single mug-sized portion using the included basket insert and a Kalita 155 filter. This flexibility makes it practical for households where needs vary day to day.

SCA Gold Cup Brewing

The full-saturation shower head distributes water evenly across the grounds for extraction. Brewing at 198–204°F for the correct time produces Gold Cup-certified results. Use a medium grind — neither too fine (over-extraction) nor too coarse (under-extraction).

Auto-On

The auto-on clock feature allows scheduling. Note: for best flavor, grind beans immediately before brewing. If using whole beans, grind the night before and store in an airtight container until morning.

After Each Use

Discard filter and grounds. Rinse the brew basket. Wash the glass carafe and lid by hand or dishwasher. Wipe the exterior.

Monthly — Descaling

Run a descaling cycle every 1–2 months or when prompted. Citric acid solution: 1 tsp per cup of water in the tank. Run a full cycle, then rinse with 2–3 clean water cycles.

Single-Cup Mode Not Working

Ensure the Kalita 155 filter is properly seated in the single-cup insert. If using the wrong filter size or type (e.g., a cone filter), drainage will be impaired.

Brewing Slowly

Descale the machine. Clean the shower head by removing and rinsing.
