Keurig Not Pumping Water After Descaling? What to Do Fast?
You just finished descaling your Keurig, hoping it would run like new again. But now it’s not pumping water at all. That can be really frustrating. I’ve been there too, and I found out what works. The most common reason your Keurig won’t pump water after descaling is a clog or trapped air bubble. The good news is — you can fix it easily at home without tools. In this article, I’ll show you exactly how to fix it, step by step, with easy-to-follow guides anyone can do.
Check the Water Reservoir and Make Sure It Is Seated Properly
Sometimes the problem is something very simple. The first thing to check is your Keurig’s water reservoir. After descaling, it’s easy to forget how things were placed before. If your reservoir is not sitting in the right spot, your Keurig might not pull water.
It won’t be able to start the brew cycle because it doesn’t feel the water is available. This happens often, especially with older models or if you moved the machine while cleaning.
Take the water tank out and look at the base. Make sure the little metal contacts or plastic connectors that touch the machine are clean. If there’s any white scale, wipe it with a soft damp cloth. Sometimes descaling liquid can leave behind leftover powder or white chunks. If they’re stuck around the bottom of the tank or inside the connection area, it can block the flow. Clean that area well.
After cleaning, fill the tank with clean water (not too full, just the normal line) and snap it back into place. Press down gently to make sure it sits perfectly. If the tank is a little loose or tilted, the machine may think it’s empty.
Wait a few seconds, then try starting the brew again — without putting in a pod, just to see if it pulls water. If it does, you’ve fixed it.
- Always clean the base where the tank connects
- Make sure no scale or debris is blocking the water lines
- Press down firmly when reattaching the tank
- Try a water-only brew test before inserting a pod
- Don’t overfill the tank when testing
Run Water Only Brew Cycles Without a Pod
Your Keurig may just need to flush out the leftover descaler. After descaling, many people forget to rinse the machine properly. That can leave the inside of your Keurig full of vinegar or descaling solution. The machine might stop working because it doesn’t like that liquid inside the pipes. It needs fresh water.
Turn on your Keurig and open the lid as if you’re going to put a pod in. Don’t put one in. Just close it again. Now press the brew button to start a water-only cycle.
Do this about 4 to 6 times. Use a large mug or cup and keep pouring the water out. You’ll probably smell vinegar or cleaning solution at first. That’s normal. The goal is to get all of that out of the pipes and pump.
Sometimes your Keurig will make noise but still not push water. If that happens, turn it off, unplug it, wait 1 minute, and try again. This gives the machine time to reset. You might also want to remove and reinsert the water tank again.
If your Keurig starts working after doing this a few times, you’ll know the problem was just leftover cleaner.
- Always run rinse cycles after descaling
- Use clean water and no pods for this process
- Repeat 4 to 6 times to flush the system
- Turn off and unplug the machine if water does not come out
- Recheck the tank placement during rinsing
Clear Any Air Bubbles That Are Trapped Inside
Air bubbles are a sneaky problem that can stop your Keurig from pulling water. This usually happens when you empty and refill the water tank. Air gets inside the water lines and blocks the pump. It makes the machine act like there’s no water, even though it’s full.
To fix this, turn off your Keurig and unplug it. Remove the water tank. Hold the tank over a sink and give it a few firm shakes. Then gently tap the bottom. This can help get rid of bubbles in the tank and valve.
Next, tip the Keurig forward slightly and gently shake it. You don’t need to be rough — just move it around a little. Sometimes the air bubble is stuck in the machine and moving it can help release it.
After that, plug it back in, attach the water tank, and try to brew again without a pod.
If it still doesn’t work, try the “suction trick.” Use a straw or a turkey baster to suck or blow air into the tank connector. This can sometimes help pull the air bubble through the system and let the pump work again.
- Air bubbles block the water pump
- Shaking the water tank can help clear bubbles
- Tilting or gently shaking the machine may release trapped air
- Use a straw or suction tool to force the bubble through
- Always unplug before moving or tilting the machine
Clean the Needles and Internal Tubes
If your Keurig still isn’t pumping water, it may be because of a clog in the needle or water lines. The needle that punctures the pod can get coffee grounds stuck inside it. Descaling doesn’t always clean this part well. If water can’t flow through the needle, the machine stops brewing.
Start by unplugging your Keurig. Open the top where you place the pod. Look inside and you’ll see a small sharp needle that punches the pod. Carefully use a paperclip or needle tool (usually comes with the Keurig) to clean out the hole. Wiggle the tool inside and clear any debris.
Also check the bottom needle (under the pod holder). It has a hole too. Pop out the holder and rinse it with warm water. Clean both holes with the paperclip.
After cleaning the needles, do a few water-only brews to flush out the system. If the needle was clogged, you should now see water coming out again.
For deeper clogs inside the tubes, fill the tank with hot (not boiling) water. Let it sit inside the machine for 10 minutes. Then turn it on and try to brew.
- Needles can get clogged with grounds or scale
- Use a paperclip to clean the needle holes
- Always unplug before cleaning the needle
- Rinse the pod holder under warm water
- Run water-only brews to flush the lines
Reset the Machine and Try Power Cycling
Sometimes the machine itself just needs a quick reset. After descaling, the internal sensors may get confused. They may think the tank is empty or blocked, even when it’s not. Doing a power cycle or reset can help fix this.
Turn off the Keurig and unplug it from the wall. Leave it unplugged for at least 5 minutes. This gives the machine time to fully reset its memory.
While waiting, remove the water tank and clean the base. Then reattach it and plug the machine back in. Turn it on and wait a minute before trying to brew.
If your Keurig has a screen or buttons, look for any reset options. Some models let you hold the brew button for 10 seconds to force a reset. Check your user guide if unsure.
You can also try switching outlets. Sometimes the power source is weak and the machine doesn’t work properly. Try plugging it into a new spot.
- Unplug the machine for 5 minutes to reset
- Clean the tank and reattach during the wait
- Try a new power outlet
- Hold the brew button if your model allows reset
- Wait one full minute before brewing again
Contact Support or Check for Replacement Parts
If none of these methods work, the problem may be deeper inside. Sometimes the water pump itself stops working. Or a small valve is damaged during descaling. These are not common, but they do happen, especially in older machines.
If your Keurig is still under warranty, contact Keurig support. They may help you fix it or replace the machine. Make sure you tell them exactly what you tried already.
Even if it’s out of warranty, you can still call. Sometimes they offer discounts on replacements.
You can also look online for replacement parts. Some people replace the pump or water valve on their own. This takes a bit of skill, so only try it if you’re comfortable. There are video guides that can help.
If the machine is very old or breaks often, it might be time for a new one.
- Contact Keurig if under warranty
- Share all the steps you already tried
- Look for repair videos if trying parts replacement
- Consider a new machine if repairs are too costly
- Ask Keurig about upgrade discounts
Final Thoughts
Fixing a Keurig that won’t pump water after descaling can be simple when you know what to check. Most of the time, it’s caused by trapped air, leftover cleaner, or a small clog. Start with the easy things like cleaning the tank, running water-only brews, and checking the needles. If that doesn’t help, do a full reset. Only consider repairs or calling support if none of the steps work. With patience, your Keurig will be working again in no time and ready for your next cup.

Frequently Asked Questions (FAQs)
Is it normal for my Keurig to stop working after descaling?
Yes, it can happen, but it’s not a big issue most of the time. After descaling, leftover liquid, air bubbles, or clogs can cause the machine to stop pulling water. This doesn’t mean your Keurig is broken. It just needs some help to get back to normal. Always run water-only brews after descaling to rinse the inside. Also make sure the tank is placed correctly and the needles are clean. These steps fix most problems caused right after descaling.
Can air bubbles really stop my Keurig from working?
Yes, air bubbles can block the pump and stop water from flowing. This happens when you refill the tank or move the machine. The pump needs a steady water line, but air stops it from working. You can clear this by gently shaking the water tank, tipping the machine, or using a straw to push or pull air. Once the air bubble is gone, your Keurig should work again like normal. Always check for this after refilling the tank.
Do I need to clean the needle after every descale?
Yes, it’s a good idea. The needle can get clogged with coffee grounds, especially if you use reusable pods. Descaling doesn’t always reach the needle. So after descaling, use a paperclip or cleaning tool to gently clean the hole in the top and bottom needle. This makes sure water can pass through easily. Doing this only takes a minute and can prevent bigger problems later on. Make it a habit after every deep clean.
Is it safe to use the straw suction trick on my Keurig?
Yes, it is safe if you do it gently. When air gets stuck inside the Keurig’s system, sucking or blowing through the water tank connector can help move it. Use a straw, turkey baster, or even your mouth to pull air. Just make sure the tank is clean before you do this. Also don’t use too much force. This trick is very helpful and many people fix their Keurig this way. It’s a fast and safe method.
Can I run hot water through the tank to clean it faster?
Yes, you can use hot water (not boiling) to help loosen clogs inside the machine. Fill the water tank with warm to hot water and let it sit in the machine for a few minutes. This can help break down any remaining descaler or scale buildup. Then run a few water-only brews. Be careful not to use boiling water because it might damage plastic parts. This is a gentle way to clean the system without using chemicals again.
Do I need to do a full reset every time?
No, you don’t always need to reset your Keurig. But if the machine freezes or won’t brew, a quick reset can help. Just unplug it from the wall and leave it off for a few minutes. This clears the internal memory and helps the sensors start fresh. You don’t have to do this every time you descale, but it’s a smart step when something goes wrong. It’s like giving your machine a quick nap.
Is it better to use vinegar or Keurig’s own descaler?
Both work, but Keurig’s descaler is made to be safer for the inside of the machine. Vinegar is cheaper and works well, but it can leave a strong smell. If you use vinegar, make sure to rinse the machine many times after. Keurig’s solution is less smelly and gentle. So if you use your machine a lot, it’s better to use the official descaler. Either way, always rinse after cleaning.
Can I fix the water pump myself?
You can, but only if you feel confident. Replacing the water pump inside a Keurig takes some time and tools. You’ll need to open the machine, which might void your warranty. There are many video guides online that show how to do it step by step. If your machine is old and out of warranty, this might be worth trying. But if it’s new, call support first to avoid any risk.
