Use straight cleaning vinegar 6%. If you're still not dispensing water try switching to the single server side, let it complete the cycle, then refill the reservoir, then switch to cups and run a cycle. Doing this I would get a red light on the cups button after a min. Then I switched back to the OZ side and kept repeating this. Also try using a injection syringe without the needle and put in at the water valve in the reservoir and pull the syringe in and out while it's cycling. This will help remove deposits on check valves and help the pump. After you get it to brew a full pot, full the tank with vinegar and run an 8 cup cycle until it starts to heat the water (that bubbling sound) then unplug it. All vinegar will stay in the cycle. Let it sit for 30 min and brew pots until no more vinegar smell or taste. Then from now on do the brew vinegar and pull the plug method once a month. Congrats you have hard water. Lol

We're a family of 5 adults and 2 children. We got this as gift 2years ago and the descale light never came on. We started noticing the water/coffee amounts were short by 1/2cup (or more). Thanks for the video, I'll be trying this soon!

I took mine apart like yours cleaned every tube the tank then threw it all back together 1 hr and it's brand new. Who needs vinegar when you have IFix IT !!!!!

Ok, so this is my follow up comment from about 3 hours earlier. This WORKED! My machine now brews a full pot of coffee! My husband and I were jumping up and down! LOL!! I had to do this procedure about 3 times. So in other words, filled up the tank 3 times, half and half water and vinegar! I rotated brews between a single cup and the full pot. The single cup was never really an issue, but the pot would only brew like 1 to 2 cups at most and then stop. Each time I ran a pot of the vinegar mixture it brewed a little more. The 'letting it sit for 30 minutes' was key!! This is when it descaled! How brilliant! I did exactly what this video said, just 3 times over. My Keurig K Duo Essential is now like perfect. Also, just an fyi... I did go out and buy the Keurig K Duo, but not the 'essentials' to replace this one when I thought it was broken. And that one wouldn't brew what I selected. I think the calibration was off or something. If we chose 8, it would brew 5. If we chose 12, it would barely make 10. This is with brewing a Pot - again, on this one - the single cup was working fine. So, we traded it in for another just like it, thinking we just got a lemon, and it did the same dang thing! Sooo- we are returning it tomorrow, and now we don't have to worry about buying another one. Ours is like new now, thanks to this video! I'm so happy!

EXCELLENT video!! Very informative, easy to listen to, follow and explained thoroughly!

Great job on this video. Thank you.

Good to know I have been doing this correctly. Personally, the machine I have has never worked correctly on the pot side, straight out of the box. Descale light comes on after 1 use and rarely does a full pot of coffee in one try. Pretty much an overpriced single cup machine. Thank you for the video.

Thank you for this video. I was completely confused as to why only one bottle of fresh water to the descaler solution. I am going to follow your video, so thank you for posting this video it's a lot more in depth to understand.

Thanks so much going to try it today!

Very good and helpful video. Thanks for sharing. 🎉😊

Thanks for the video. Good tip to let it stew in the heating coil. Still trying to figure out that dang descale light. Mine hasn't been lighting up, but hope it's still not counting away even though I just cleaned.

Very helpful. Thanks for the information ❤️🙏🏻👍🏻

Thank you! Very helpful.

Excellent video. Thank you 😊

Thanks! You definitely can tell yer a Dad and a mechanic. Great video! Appreciate the tutorial. 🤍🩵💙🤙🏼

Thnx for all the useful help!!!!!👉🏻🤘🏻

Great video

thanks. yeah my issue is the light is solid, so from your explanation that means it needs descaling. However, I just bought this machine, brand new, and when I hit the Oz button then the 8 (or any other size), nothing happens. I hear some clicking then nothing

I use filtered well water and it took a year of daily use for the descale light to come on. Great video.

I just purchased a used duo Kerrigan and I am trying to clean it…I was able to clean the pod side but can’t seem to get the coffee pot side to fill up with the solution..what am I doing wrong???so frustrated

Thanks for this video. My "Descale" light stays on constantly. I've used vinegar, it will heat up, run the vinegar through allowing about 2 ounces of vinegar/water then shuts down. Is it too late for my machine? Should I keep trying?

Thanks 😊

Hi, can denture cleaner tabs be utilized to descale/clean the machine? Purchased Jan 2023. I only brew a full carafe about 1-2x/week (summer), but do utilize the kcup side daily (fall/winter (coffee temp/flavor preferences). I have SUPER hard water, so I’ve been using the denture cleaner tabs(2)about 1-2x/month (summer) and about 1x/week (fall/winter). I try to avoid vinegar (smell/taste), heard the tabs were an alternative. Am I overkilling it? 🤦🏻‍♀️

I have never descaled ours - had it for 2 years! It does not have a descale light. So now, when we brew a pot, it brews a little then stops. The single cup is still working. I'm so excited to try this. If it works - I will let you know! Either way, it was a very helpful video, thanks for taking the time to do it!

What do I do when it stops brewing after less than 2 cups when I have the water reservoir is full?

What if the machine wont let any water out? Like itll make the sound and you can tell it is trying, but it wont brew anything.

I just descaled my supreme plus and it no longer powers up and doesn’t work after completing the descaling. What have I done wrong. Looks like need a new one but worried about it happening again.

Help lol…our descaling light came on and we followed it great direction. But it won’t run through with the single or carafe fully. Barely in the single and only 4ish cups in the carafe. It worked fine yesterday?!

Any ideas on how to get it to make half more than half of the carafe?

My Keurig Duo is new (just like one in viedo) I have tried multiple times to correct my problem. I have followed your steps, step by step and still no luck. Descale/Add H2O light on and 12 cup light appears to possibly be laminating from it rather than actually on. I have a couple pics, if you could help me with attaching them or how to send them. Excellent video!!!Thanks

What if the machine is pouring out MORE water for each cup? 🤷🏻‍♀️ My machine’s descale light isn’t on but should I do it anyway?

My will run the cleaning solution through the kcup side but only a small amount on the carafe side. Won't do the full 8 cups

Hey so my 8 10 and 12 buttons won't stop blinking and nothing is showing me how to fix that what do I do?

How do i know when to descale my model with the programmable? Do i have to remember every 3 to 4 months, does my model notify me? Thank you for your videos

Hi! I have this exact machine! This doesn’t contain or need the old Keurig filter pods does it?

I cannot get lights to flash and therefore am unable to flush vinegar or solution through. I was able to run several cups of vinegar through but now am unable to. Help.

We never used the carafe side (I think ever?) And today we finally used it (8 cups selected) only for it to not even brew halfway before shutting off completely (didn't even kick in the hot plate) Went to try the kcup side - fearing the worst - and sure enough as soon as I clicked the kcup button it all lit up with that solid blue light for descaling Now I'm running as this video instructs and I got through the 8oz part, but now the carafe side is pumping out nothing at all (but it's clearly trying) Any ideas?

The last couple times I’ve run descale cycles, it won’t brew a whole pot at once. After trying several times, I decided to let it rest. Is it possible that it’s just so full of deposit that I will have to do it several times letting it rest between each until the tank empties? It only trickles a little bit before stopping

Can you post a video of how to take the back off?

How do get the light to turn off? Is there a reset? I did do the descaling?

Thanks for the info. My problem is it's not making a full pot. It brews more like only 10 cups. Wondering if this would fix the problem I'm having.

I have a different issue, same machine. The kcup button is lit up GREEN and won't do anything??? It's only a year old. Any suggestions??

What water would you suggest? I have well water. Thanks.

My Kerrigan dual doesn’t have a descal light

My it's not ever turn the descale light but it started to give me less than 12 cups on the brew part 😢 using this hoping it work

My light is on but not doing anything not running water is not letting me clean it

I think I added too much vinegar,my coffee pot won't run now..any suggestions??

Keuric deo add water light keeps flashing

Did I miss where you said how to get Descale sign off?

Trying to descale but water wont even come out on the cup side.

My Cup lights are Not on, so water won't run

Mine just has a tiny drip 😢

Nice video but no idea how to take the back off

I tore mine apart and I had calcium buildup inside the tubing!

Descaling my keurig the way it said and it ruined my pot.

What's craft

I’ve descaled several times and still the light won’t turn off…. I’m a little annoyed to be honest. I need my coffeee but I don’t want to spend money on a new one! 😫😂 #coffeeaddictproblems

Best water to use is RO it has nothing in it and you’ll never have to descale it

World after only 40 days of using this machine, I got frustrated, I have watched a lot of videos and nothing I solved. If you clean your machine as indicated, try the method to eliminate flaking. After Elena, just clean the needle that pierces the capsule and that's it, gentlemen. With love I hope it works for you. Do not manipulate the machine as this could damage it even more. Thank you Blessings! 🙏✌️🫶
