First Steps
Unpack the machine and remove all packaging materials.
Place the coffee maker on a flat, stable surface near a power outlet.
Ensure the water reservoir, filter basket, and carafe are clean before first use. Rinse them with warm water to remove any dust or manufacturing residues.
Step-by-Step Brewing Instructions
Step 1: Fill the Water Reservoir
Open the water reservoir lid located on the top of the machine.
Using the built-in water reservoir marks, fill with cold, clean water corresponding to the number of cups you want to brew (up to 12 cups).
Avoid exceeding the MAX fill line to prevent overflow.
Step 2: Prepare the Coffee Grounds
Remove the filter basket from the machine.
Insert a standard #4 cone-shaped paper filter or use the included washable filter.
Add the desired amount of ground coffee into the filter. The general guideline is 1 to 2 tablespoons of coffee per 6 ounces of water depending on your preferred strength.
Level the coffee grounds for even extraction.
Step 3: Insert the Filter Basket
Place the filter basket back into the coffee maker securely.
Ensure the basket lid closes properly to avoid spills.
Step 4: Place the Carafe
Position the glass carafe firmly on the warming plate beneath the filter basket.
Confirm the carafe lid is on and properly sealed to keep coffee fresh.
Step 5: Start Brewing
Press the Power button located on the front panel.
The brewing process will begin immediately, and the indicator light will illuminate.
The coffee maker will brew the selected amount of coffee; this usually takes about 8-10 minutes for a full pot.
The Ninja CE251 features a Pause & Serve function allowing you to remove the carafe mid-brew to pour a cup without spilling.

Maintenance and Cleaning Guide
Proper maintenance is crucial for the longevity and performance of your Ninja CE251 coffee maker. Regular cleaning prevents buildup of coffee oils, mineral deposits, and bacteria, ensuring every cup tastes fresh.
Daily Cleaning
Turn off and unplug the coffee maker.
Remove the carafe and wash it with warm, soapy water. Rinse thoroughly.
Take out the filter basket and discard used grounds and paper filter.
Rinse the filter basket with warm water.
Wipe down the exterior of the coffee maker with a damp cloth.
Dry all parts thoroughly before reassembling.
Weekly Cleaning
Clean the water reservoir by wiping the inside with a damp cloth.
If you notice residue or mineral buildup, use a solution of equal parts water and white vinegar to wipe the interior. Rinse well after.
Monthly Deep Cleaning (Descaling)
Over time, minerals from water can accumulate inside your coffee maker. Descaling removes these deposits and keeps your machine running smoothly.
Descaling Steps:
Fill the water reservoir with a mixture of half white vinegar and half water up to the MAX fill line.
Run a brew cycle without coffee grounds.
Halfway through, pause the machine and let the vinegar solution sit for 30 minutes to an hour.
Complete the brew cycle.
Run two to three cycles of clean water to rinse out the vinegar taste.
Wipe the carafe and filter basket before the next use.
