Four Keurig parts account for nearly every fix: the charcoal water filter cartridge, the water reservoir and its lid, the entrance and exit needles, and the K-cup holder assembly. Only the filter is a scheduled item, and Keurig's own guidance is to replace the cartridge every 2 months or 60 tank refills. The needles are not a replacement item at all in most cases; they are a cleaning job.
Keurig parts, by symptom
| Symptom | Part or job | Scheduled? |
|---|---|---|
| Chlorine taste, flat coffee | Water filter cartridge | Yes, every 2 months or 60 tank refills |
| Pods not piercing, grounds in the cup | Entrance and exit needle cleaning | No, clean as needed |
| Cracked or leaking tank | Water reservoir and lid | No, replace on damage |
| Holder will not latch, pod sits crooked | K-cup holder assembly | No, replace on damage |
| Short or partial cups, loud pump | Descale first, then check needles | Descale on the schedule for your water |
| Puddles under the machine | Drip tray, or a seal failure inside | No |
The filter is the only true consumable
Keurig's water filter cartridges exist to strip chlorine, and the company puts a clear number on the change interval: every 2 months or 60 tank refills. Miss it and the cartridge stops helping long before it looks dirty. Most people notice the difference on light roasts first, where chlorine flattens the aromatics. Details on fitting are in Keurig water filter replacement.
A filter is not a descaler. Scale still builds in the boiler, and the fix for that is the descaling routine in how to descale a Keurig. Machines that get neither treatment are the ones that eventually stop pumping.
Needles get cleaned, not replaced
The upper entrance needle and the lower exit needle clog with coffee fines and dried grounds. Symptoms are grounds in the cup, pods that do not pierce cleanly, and cups that come out short. A straightened paperclip through the needle holes with the machine unplugged clears most of it, and the tool Keurig ships with some models does the same job. Replacement needles are rarely the answer unless one is visibly bent.
If cleaning does not fix a short cup, the problem is usually pump or scale related. Start with Keurig not pumping water.
Reservoirs, holders, and the model number problem
Tanks and holders are model specific and they are not interchangeable across the range, which is why generic listings are risky. Find the model on the sticker underneath or on the back before ordering, and if you are not sure which one you own, work through which Keurig do I have. A K-Slim tank will not fit a K-Supreme, and a K-Classic holder will not fit a K-Express.
Order by model number
Check the sticker on the base of the machine first, then search with the model name included.

FAQ
How often do you change a Keurig water filter? Keurig says every 2 months or 60 tank refills. That is the only Keurig part with a published schedule.
Can you replace the needle in a Keurig? In most cases you clean it rather than replace it. A straightened paperclip through the needle holes with the machine unplugged clears the fines that cause grounds in the cup and partial brews.
Are Keurig water reservoirs interchangeable between models? No. Tanks and K-cup holders are model specific. Check the model number on the sticker underneath the machine before ordering a replacement.
