How To Safely Drain Your Keurig Coffee Maker

Quick answer

• Turn off and unplug your Keurig. Safety first, always.
• Remove the water reservoir. Dump any leftover water.
• Run a brew cycle with no pod. This clears the internal lines.
• Let it sit empty for a bit. Air drying helps.
• Check your specific model manual. They can vary slightly.
• Store it somewhere dry. Protect it from the elements.

Who this is for

• Anyone moving their Keurig to a new spot. Gotta get that water out.
• People storing their Keurig for the off-season. Winterizing, anyone?
• Folks troubleshooting a clogged machine. Sometimes a good drain is all it needs.

What to check first

Brewer type and filter type

Your Keurig model is key. Is it a K-Classic, K-Elite, K-Slim, or something else? The general process is similar, but some models might have specific release valves or steps. If you use a reusable K-Cup filter, remove that too.

Water quality and temperature

While draining, you’re not brewing, so water temp isn’t a huge concern. However, if you’ve been using hard water, mineral buildup is more likely. This is a good reminder to descale regularly. For draining, just make sure the machine is cool to the touch.

Grind size and coffee freshness

Not applicable when draining. You’re not brewing coffee, so no grounds are involved. Focus on getting the water out.

Coffee-to-water ratio

Again, not relevant for draining. We’re just emptying the water. No coffee means no ratio to worry about.

Cleanliness/descale status

This is actually a good time to think about it. If you’re draining your Keurig because it’s been sitting for a while or you’re moving it, make sure it’s clean before you store it or put it back into service. A good descale now means better coffee later.

Step-by-step (brew workflow)

1. Unplug the Keurig.

• What “good” looks like: The power light is off, and the machine is completely dead. No humming, no lights.
• Common mistake: Forgetting to unplug it. Electricity and water are a bad mix, folks. Always disconnect power first.

2. Remove the water reservoir.

• What “good” looks like: The reservoir lifts off easily, and you can see the opening where it connects to the machine.
• Common mistake: Yanking too hard. Some reservoirs have clips or guides. Gentle pressure is usually best.

3. Empty the water reservoir.

• What “good” looks like: The reservoir is completely empty, with no residual water sloshing around.
• Common mistake: Not getting all the water out. A little bit left can still cause issues if it freezes or stagnates.

4. Locate the drip tray and any removable parts.

• What “good” looks like: You can see the drip tray and any other small pieces that are designed to come off.
• Common mistake: Forgetting about the drip tray. It holds water too, and needs to be emptied.

5. Remove the drip tray.

• What “good” looks like: The drip tray slides or lifts out cleanly.
• Common mistake: Trying to drain the machine with the drip tray still in place. You’ll just make a mess.

6. Empty the drip tray.

• What “good” looks like: The drip tray is dry and clean.
• Common mistake: Leaving old coffee drips in the tray. Gross, and can lead to mold.

7. Place the brewer over a sink or basin.

• What “good” looks like: The Keurig is positioned so any remaining water will flow directly into the sink, not onto your counter.
• Common mistake: Draining it on the counter. Trust me, you don’t want a soggy countertop.

8. Run a brew cycle (no pod).

• What “good” looks like: Water flows from the needle assembly into the sink. You might hear a gurgling sound as the internal lines empty.
• Common mistake: Putting a K-Cup back in. You’re trying to drain it, not brew.

9. Repeat the brew cycle a couple of times.

• What “good” looks like: Less and less water comes out with each cycle, until it’s just a trickle or nothing at all.
• Common mistake: Stopping after one cycle. You need to ensure the internal pump and lines are cleared.

10. Allow the machine to air dry.

• What “good” looks like: The reservoir is off, the drip tray is out, and the machine is open to the air.
• Common mistake: Putting the reservoir back on immediately. Give it a chance to dry out fully.

11. Reassemble (if storing) or set aside.

• What “good” looks like: If you’re storing it, put the reservoir and drip tray back on. If you’re moving it, just make sure everything is dry.
• Common mistake: Leaving parts loose if you’re moving it. They can get lost.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Not unplugging the Keurig	Risk of electric shock. Seriously, don’t do this.	Always disconnect power before doing any maintenance.
Forgetting to remove the water reservoir	Water remains trapped inside, potentially leading to mold or freezing damage.	Remove the reservoir first and empty it completely.
Not emptying the drip tray	Stagnant water, potential for mold and an unpleasant smell.	Remove and thoroughly empty the drip tray.
Not running enough brew cycles	Internal lines and pump still contain water, risking freezing or clogs.	Run 2-3 brew cycles (without a pod) until water flow stops.
Storing a wet machine	Mold growth, unpleasant odors, potential for internal component damage.	Ensure all parts are completely dry before reassembling or storing.
Forcing parts that are stuck	Breaking plastic components, rendering the machine unusable.	Check your specific model’s manual or online guides for proper removal techniques.
Using harsh chemicals for draining	Damage to internal seals and plastic components, potential for contamination.	Stick to plain water for draining. Use descaling solution only as recommended by the manufacturer.
Not checking the manual	Missing model-specific steps or warnings, leading to damage or inefficiency.	Consult your Keurig’s user manual for precise instructions.
Leaving a pod in during draining	Incomplete draining, potential for grounds to clog the system.	Always ensure no K-Cup or reusable filter is in the brewer.
Draining on a counter	Water spills, potential for electrical hazards if water gets into vents.	Position the brewer over a sink or a large basin.

Decision rules (simple if/then)

• If you are moving your Keurig, then you must drain it because you don’t want water sloshing around during transport.
• If you are storing your Keurig for an extended period, then you should drain it thoroughly because stagnant water can breed mold and bacteria.
• If you notice a strange smell coming from your Keurig, then draining and cleaning it might help because old water can go rank.
• If your Keurig seems to be brewing slowly or inconsistently, then draining and running a descaling cycle might be the fix because mineral buildup is a common culprit.
• If you’ve just moved and are setting up your Keurig, then draining it first is a good idea because it ensures no residual water from the move is sitting in the machine.
• If you are unsure about a specific step for your model, then consult your owner’s manual because Keurigs can have minor variations.
• If you hear unusual noises during the draining process, then stop and check for blockages because something might be lodged in the system.
• If you’re draining your Keurig in a cold environment, then be extra sure it’s completely dry because freezing water can expand and damage components.
• If you are troubleshooting a leak, then draining the machine can help you inspect components without water obscuring the issue.
• If you’ve just finished a descaling cycle, then draining the machine afterward is a good practice because it flushes out any loosened mineral deposits.
• If you plan to use your Keurig again soon after draining, then a quick rinse cycle with fresh water is a good idea because it ensures no lingering stale water is used for your first brew.

FAQ

How often should I drain my Keurig?

You don’t need to drain it routinely unless you’re moving it, storing it, or troubleshooting. For daily use, regular descaling is more important.

Can I just leave water in the reservoir if I’m not using it for a few days?

It’s best to empty the reservoir if you’ll be away for more than a day or two. Stagnant water can become a breeding ground for bacteria and algae.

What if my Keurig doesn’t seem to drain completely?

Try running a few more brew cycles. If it still seems blocked, check your manual for specific troubleshooting steps related to clogs or pump issues.

Is it safe to drain my Keurig in freezing temperatures?

No. If you must drain it in cold weather, ensure it’s completely dry afterward, or bring it inside to warm up before draining to avoid freezing damage.

Do I need to descale before draining?

Not necessarily. You can drain it anytime. However, if you’re draining it for storage, descaling first is a good idea to start fresh later.

Will draining affect my Keurig’s settings?

No, draining the water won’t reset any of your saved preferences or brew settings.

What’s the best way to store a drained Keurig?

Store it in a clean, dry place. Reassemble the reservoir and drip tray to keep dust out.

Can I use a syringe to get the last bit of water out?

While you might be tempted, it’s usually unnecessary and could potentially damage internal seals. Running extra brew cycles is the recommended method.
