How to Reset Keurig Coffee Maker: Power, Descale and Purge

Quick answer: How to reset Keurig coffee maker models is mostly a power cycle, because Keurig’s Use & Care Guides don’t list a reset button. Turn the brewer off, unplug it, wait, and plug it back in. After a stalled descale, Keurig says to leave it unplugged for at least 30 minutes. A stuck descale light only clears after a full descale.

“Reset” means different things on a Keurig. Sometimes it’s a dead screen. Sometimes it’s a light that won’t go off.

I’d figure out which one you have first. Each fix is different, and none involves a hidden button.

Does a Keurig Have a Reset Button?

Not on the models covered here. The guides for the K-Supreme Plus, K-Elite and K-Duo show no dedicated reset button. Their troubleshooting relies on powering off, unplugging, running the right maintenance program, or calling Customer Service.

Seen “hold these two buttons to reset” tips online? Check them against your own manual first. Button combinations do real things on these machines: on a K-Supreme Plus, holding 8oz and 12oz together starts Descale Mode.

Why It Happens

Most common first:

1. No power, or it shuts itself off. Often an auto-off timer or an overloaded outlet.
2. Won’t brew, or pours a partial cup. Low water, a clogged exit needle, a reservoir lifted mid-brew, or scale.
3. The descale light stays on. It’s waiting for a complete descale.
4. Odd light patterns. Some mean “do this,” others mean “call Keurig.”

Problem	Reset move	Model in the guide
Frozen or unresponsive	Power off, unplug, wait, plug in	All
Turns off on its own	Check auto-off timing	K-Supreme Plus, K-Duo (5 min), K-Elite (2 hours)
Short cups	Brew + 12oz for 5 seconds from off	K-Supreme Plus
All size lights on	Lift handle, remove pod, mug, press power	K-Elite
Stalled during descale	Unplug at least 30 minutes, then rinse	All three
Descale light stays on	Complete the full descale	K-Supreme Plus

How to Reset Keurig Coffee Maker Step by Step

Step 1: Power Cycle

1. Press power to switch off.
2. Unplug from the wall.
3. Wait a few minutes (my suggestion; Keurig doesn’t give a number).
4. Plug into its own grounded outlet, press power, and run a brew without a pod.

Keurig’s guides say the brewer should sit on its own circuit, away from other appliances, because an overloaded circuit can stop it working properly. Sharing a strip with a toaster? I’d fix that first.

Step 2: Rule Out Auto-Off

A machine that “keeps turning off” may just be saving energy. The K-Supreme Plus and K-Duo shut down 5 minutes after the last brew, per their guides. The K-Elite defaults to 2 hours, adjustable in 15 minute steps.

When you see a dark screen, press power to wake it. With the button on and a working outlet but still no power, Keurig says to contact Customer Service.

Step 3: Purge a Short Cup (K-Supreme Plus)

Its guide gives a specific purge:

1. Power off.
2. Hold the brew button and 12oz button together for 5 seconds, until water starts dispensing.
3. Release, let it purge, and tip the water into the sink.
4. Press power to restart.

Cups still short? Clear the exit needle with a straightened paper clip and wash the pod holder, as the guide describes. In practice, a needle packed with grounds is the cause I’d bet on first for a machine that’s otherwise fine.

Step 4: All Lights On (K-Elite)

When the 4, 6, 8, 10, 12oz and ICED lights all glow at once, the K-Elite guide says to lift the handle, remove any pod, close it, set a large mug on the drip tray and press power once. Hot water may come out.

Don’t confuse that with blinking. If those size lights all blink together, Keurig says to contact Customer Service, and the K-Duo guide says the same when all its buttons blink at once.

Step 5: Recover From a Stalled Descale

Heavily scaled machines sometimes choke on descaling solution: little or no output, then the sound of air blowing out. Keurig’s fix:

1. Turn off and unplug.
2. Pour out any solution left in the reservoir, rinse it and refill with fresh water.
3. Plug back in, power on, and repeat the fresh water rinse.
4. Still stuck? Leave it unplugged for at least 30 minutes, then continue rinsing.

How to Clear the Keurig Descale Light

There’s no shortcut, and honestly I’d stop looking for one. The K-Supreme Plus guide says the notification turns off only after the full descaling procedure:

1. Empty the whole bottle of Keurig Descaling Solution into the reservoir, then refill the bottle with water and add that.
2. With the machine plugged in and switched off, hold 8oz and 12oz together for 3 seconds to enter Descale Mode.
3. When it flashes, press brew and dump each mugful in the sink. Repeat until ADD WATER lights up.
4. Rinse the reservoir, fill to MAX, and keep running rinse brews until DESCALE goes dark.

Budget 15 to 20 minutes on the K-Supreme Plus. The K-Elite takes around 45 minutes and the K-Duo about 75, per their guides, since their rinse routines are longer; the K-Elite wants at least 12 rinsing brews.

Mistakes to Avoid

• Paper cups. Keurig specifies a large ceramic mug for descaling.
• A pod left in the holder during a purge or descale.
• Brewing straight after cold storage. Below freezing? Keurig says let it warm at room temperature for at least 2 hours.
• Distilled water. Keurig suggests bottled or filtered water if your tap tastes off, but says not to use distilled.

When to Call Keurig

Call Customer Service if every size light blinks together, if there’s no power on a dedicated outlet, if ADD WATER stays lit after refilling and reseating the reservoir, or if partial cups survive two descales. The guides list the line as 1-866-901-2739.

Beyond cleaning and descaling, the K-Supreme Plus guide is plain: “this brewer is not user serviceable.” My advice is to take that literally.

Frequently Asked Questions

Does a Keurig have a reset button?

Not on the K-Supreme Plus, K-Elite or K-Duo, according to their guides. You reset by powering off, unplugging and running the right maintenance step.

How long should I unplug my Keurig to reset it?

Keurig gives no figure for a simple power cycle, so a few minutes is my default. For a stalled descale, Keurig says at least 30 minutes.

How do I reset my Keurig after descaling?

Keep running fresh water rinses until the descale light goes out. On a K-Supreme Plus, that’s what exits Descale Mode.

Why won’t my Keurig turn on after unplugging it?

Use a dedicated grounded outlet, not a crowded strip. No power even then? Call Customer Service.

Why is my Keurig only brewing half a cup?

Usually a clogged exit needle, a reservoir lifted mid-brew, or scale. Clean the needle, run a rinse without a pod, and descale if needed.
