Emptying Your Keurig Coffee Maker: A Quick Tutorial

Quick answer

• You don’t “empty” a Keurig in the traditional sense like a drip coffee maker.
• The main point is draining any residual water from the reservoir and internal lines.
• This is crucial for storage, travel, or preventing mineral buildup.
• Most Keurigs have a simple process involving running cycles without a pod.
• Always unplug the machine before any manual draining or deep cleaning.
• Check your specific model’s manual for exact instructions.

What this problem usually is (and is not)

• This isn’t about emptying grounds or a carafe. Keurigs use pods.
• It’s about getting the water out of the system. Think of it like winterizing an RV.
• You’re not trying to get every single drop out, just the bulk of it.
• This process is generally safe and straightforward. No need for specialized tools.
• It’s not a daily task, but good to know for specific situations.

Likely causes (triage list)

Water Reservoir

• Cause: Water left in the reservoir.
• Confirm: Visually inspect the reservoir. Is it full or partially full?

Internal Water Lines

• Cause: Water trapped in the heating element and brewing mechanism.
• Confirm: After draining the reservoir, run a few brew cycles with no pod. Water should still come out.

Machine Setup

• Cause: Machine is plugged in and ready to brew.
• Confirm: Ensure the machine is powered on when running drain cycles.

Scale and Cleaning

• Cause: Mineral buildup can sometimes restrict water flow, making draining harder.
• Confirm: If draining is unusually slow or sputtering, scale might be a factor.

Fix it step-by-step (brew workflow)

1. Unplug the machine.

• What to do: Disconnect the power cord from the wall outlet.
• What “good” looks like: The machine is completely inert. No lights, no sounds.
• Common mistake: Forgetting this step. It’s a safety basic. Always unplug before fiddling.

2. Remove the water reservoir.

• What to do: Lift the reservoir straight up and off the base.
• What “good” looks like: The reservoir is detached cleanly.
• Common mistake: Forcing it. Some reservoirs have clips or need a slight wiggle.

3. Empty the reservoir.

• What to do: Pour out any remaining water into a sink or drain.
• What “good” looks like: The reservoir is completely empty.
• Common mistake: Leaving a little water. Just get the bulk out.

4. Place the reservoir back on the base.

• What to do: Align the reservoir and press it down firmly until it clicks into place.
• What “good” looks like: The reservoir is securely seated.
• Common mistake: Not seating it properly. The machine won’t run without a secure reservoir.

5. Ensure no K-Cup pod is in the holder.

• What to do: Lift the handle and visually check that the pod holder is empty.
• What “good” looks like: The pod holder is clear.
• Common mistake: Accidentally leaving a pod in. This will interrupt the drain cycle.

6. Plug the machine back in.

• What to do: Reconnect the power cord to the wall outlet.
• What “good” looks like: The machine powers on, lights up.
• Common mistake: Forgetting to plug it back in. You need power to run the pump.

7. Place a mug on the drip tray.

• What to do: Position a sturdy mug or container to catch the water.
• What “good” looks like: The mug is centered under the dispenser.
• Common mistake: Using a flimsy cup that could tip. You’ll have a mess.

8. Run a brew cycle (without a pod).

• What to do: Select a small brew size (e.g., 6 oz) and press the brew button.
• What “good” looks like: Water flows into the mug. You’ll hear the pump working.
• Common mistake: Not running enough cycles. You need to flush the lines.

9. Repeat brew cycles until no more water comes out.

• What to do: Continue running 6 oz cycles, emptying the mug each time.
• What “good” looks like: The cycles eventually stop producing water, or only a few sputtering drops come out.
• Common mistake: Stopping too soon. Give it at least 3-5 cycles, maybe more.

10. Run a final rinse cycle (optional but recommended).

• What to do: After draining, fill the reservoir with fresh water and run one last cycle.
• What “good” looks like: Clean water dispenses, rinsing any lingering residue.
• Common mistake: Skipping this if you plan to brew coffee immediately after draining.

11. Unplug the machine again.

• What to do: Disconnect the power cord.
• What “good” looks like: Machine is off and safe for storage or transport.
• Common mistake: Leaving it plugged in if storing long-term.

Prevent it next time

• Clean regularly: Wipe down the exterior and drip tray after each use.
• Descale often: Follow manufacturer recommendations, usually every 3-6 months.
• Use filtered water: Reduces mineral buildup significantly.
• Don’t let water sit: If you won’t use the machine for a few days, drain the reservoir.
• Check the pod: Ensure K-Cups are properly seated and not damaged.
• Inspect the needle: Occasionally check the exit needle for clogs.
• Listen to your machine: Unusual noises can signal issues.
• Keep it dry: If storing, ensure it’s fully drained and dry.
• Read the manual: Your specific model might have unique features.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Not unplugging before draining	Risk of electrical shock or accidental brewing	Always unplug. Check the manual for safety.
Leaving water in the reservoir	Stagnant water can grow bacteria or mold	Drain reservoir completely.
Not running enough drain cycles	Water remains in internal lines	Run 3-5 cycles, or until sputtering stops.
Forgetting to re-seat the reservoir	Machine won’t operate	Ensure reservoir clicks firmly into place.
Using tap water without filtering	Faster scale buildup, affects taste	Use filtered or bottled water.
Ignoring descaling prompts/schedule	Reduced brewing speed, weak coffee, machine failure	Descale according to manual instructions.
Storing a wet machine	Mold, mildew, potential damage	Ensure machine is completely dry before storing.
Not checking for a pod before draining	Brew cycle interrupted, water may not drain fully	Always confirm the pod holder is empty.
Using a small, unstable mug	Spills, mess, potential burns	Use a sturdy, appropriately sized mug.
Not cleaning the drip tray	Grime buildup, potential clogs	Clean drip tray regularly.

Decision rules (simple if/then)

• If you’re storing the Keurig for winter or travel, then drain it completely because you want to prevent freezing damage and water stagnation.
• If the machine has been sitting unused for over a week, then consider draining the reservoir because fresh water is always best for taste and hygiene.
• If you notice a sputtering sound or slow brew time, then it’s likely time to descale because mineral buildup is restricting water flow.
• If you see any visible mold or slime in the reservoir, then empty it immediately and run several cleaning cycles with a descaling solution because it’s a hygiene issue.
• If you’re moving the Keurig to a new location, then drain it thoroughly because you don’t want sloshing water during transit.
• If the machine is making unusual noises during a brew cycle, then check the water level and ensure the reservoir is seated correctly because these are common causes.
• If you’re experiencing weak or watery coffee, then first check your K-Cup and brew size, but also consider if a descaling is due because scale affects extraction.
• If you’re unsure about a specific step for your model, then consult your owner’s manual because it has the most accurate information.
• If you plan to use the machine again shortly after draining, then run a rinse cycle with fresh water to ensure the taste is clean.
• If you notice any leaks, then immediately unplug the machine and inspect the reservoir seal and connections because leaks can indicate a damaged part.

FAQ

Q: Do I need to empty my Keurig every day?

A: No, not unless you want to. It’s generally fine to leave water in the reservoir for a few days. However, for best taste and hygiene, draining it if you’ll be away for a week or more is a good idea.
