How to Fix a Keurig That Won’t Brew
Your Keurig stopped working. Before you throw it away — read this first.
Most of the time the machine is not broken. It just has a clog or a simple glitch. I’ve helped hundreds of people fix this exact problem. Most of the time it costs nothing and takes under 15 minutes.
Find your problem in the table below. Click the button and it will take you straight to the right fix.
Always unplug your Keurig before touching the inside. The needles inside the lid are sharp. Let the machine cool for 10 minutes before you begin.
| What you see | What it means | Go to |
|---|---|---|
| Only a tiny bit of coffee comes out | Needle clogged with coffee grounds | Fix 1 → |
| “Add Water” light on — but tank is full | Float disc inside tank is stuck | Fix 2 → |
| Descale light won’t turn off | Needs more rinse cycles to reset | Fix 3 → |
| Machine hums but no water comes out | Air bubble trapped inside the tubes | Fix 4 → |
Only a Little Coffee Comes Out
💰 Free — no parts neededInside the lid is a tiny metal needle. It pokes a hole in your coffee pod so hot water can flow through. Over time, old coffee grounds pack inside that needle like a clog in a straw. Water can’t get through — so you only get a tiny trickle.
Do this cleaning once a month. It takes two minutes and keeps your Keurig brewing at full strength.
“Add Water” Light On — But the Tank Is Full
💰 Free — no parts neededInside your water tank is a small plastic disc that floats up and down. The machine reads it to know how much water is there. Minerals in tap water make the disc sticky — it gets stuck at the bottom, and the machine thinks the tank is empty even when it’s full.
Using filtered water instead of tap water slows down mineral buildup and keeps that disc moving freely longer.
Descale Light Won’t Turn Off
💰 Under $10Tap water leaves white mineral deposits inside your machine over time. The descale light means it’s time to clean them out. After you clean it, the light stays on because the machine needs to count a specific number of plain-water rinse cycles before it resets. Most people stop too soon.
Switch to filtered water and you’ll need to descale far less often. It also makes your coffee taste better.
Machine Hums But No Water Comes Out
💰 Free — no parts neededIf your water tank ran completely dry, the pump sucked in a large air bubble. That bubble is now stuck inside the tubes — the motor runs fine but can’t push water past it. Think of it like air trapped in a garden hose after the water shuts off.
Never let the tank run completely empty. Top it off when it gets low and you’ll never deal with this problem again.
🤔 Still Not Working After All Four Fixes?
If you’ve tried everything above and the machine still won’t brew, it most likely has a pump or circuit board problem. At that point the repair costs more than a new machine.
Before you buy a new one: Call Keurig at 1-866-901-2739. Tell them your model number and what it’s doing. They have a surprisingly generous replacement policy — even for machines out of warranty. Worth a five-minute call.
