Steps

Goal: Unplug the unit, locate the leak, fix the reservoir or drip tray, clean the needle, and know when to replace the Keurig.

  • Unplug the Keurig. Empty the reservoir and remove the drip tray.
  • Good: Unit is off and empty. Proceed to Locate the leak.
  • Bad: Unit is hot—wait for it to cool.

Locate the leak

Goal: Identify where the water or coffee is escaping.

  • Fill the reservoir and run a brew cycle. Watch where water or coffee appears—around the reservoir, from the drip tray, or from the brew chamber.
  • Good: You see the leak at a specific location. Proceed to Reservoir path or Drip tray path based on location.
  • Bad: Leak is unclear—dry the area and run again to confirm.

Reservoir path

Goal: Check the reservoir seating and fill level.

  • Remove the reservoir and reinstall it firmly until it clicks or sits flush. A loose reservoir can leak at the seal.
  • Confirm the reservoir is not filled above the max line. Overfilling causes overflow during the brew cycle. Fill to the max line or fewer cups than you are brewing.
  • Inspect the reservoir for cracks around the fill opening or base. A cracked reservoir cannot be reliably repaired—replace it with an exact match (order by model number).
  • Good: The reservoir is seated and intact. Reseat firmly and run again—the leak should stop.
  • Bad: The reservoir is cracked—replace it. If the leak continues after reseating, check the drip tray and brew chamber.

Drip tray path

Goal: Check the drip tray and cup size.

  • Confirm the drip tray is fully seated and the cup stand is in place. A misseated tray can cause spills.
  • Brewing into a cup that is too small or not centered causes coffee to spill onto the drip tray and overflow. Use a mug that fits under the spout and is at least as tall as your brew size.
  • If the leak persists, unplug the machine and let it cool. Lift the K-Cup holder and clean the exit needle with a paper clip or Keurig needle cleaning tool. Run a descaling cycle per your model instructions.
  • Good: Drip tray seated and cup size correct. The leak stops.
  • Bad: The leak continues—inspect the reservoir for cracks. If water pools under the base, call a technician.

When to get help

Call an appliance technician if:

  • The leak continues after you have checked the reservoir, drip tray, and brew chamber.
  • The reservoir is cracked.
  • Water pools under the base or near electrical components.

For many Keurigs, replacement is often more practical than repair. For other plumbing fixes, see Fix a leaking faucet or How to unclog a drain.

Verification

  • No water or coffee dripping from the reservoir, drip tray, or brew chamber during a brew cycle.
  • Coffee flows into the cup without overflow.
  • No puddles under or around the Keurig after brewing.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Confirm where Pinpoint the leak—around the reservoir, from the drip tray, or from the brew chamber.
  2. Reservoir seating and fill level Reseat the reservoir and confirm it is not overfilled.
  3. Drip tray and cup size Confirm the drip tray is seated and you are brewing into an adequately sized cup.
  4. Clean needle and descale Clean the exit needle area and run a descaling cycle.
  5. Call a pro or replace Leak persists, reservoir cracked, or water under base—call a technician or replace the unit.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • Where the leak appears (reservoir, drip tray, brew chamber)
  • Keurig model number
  • Whether the reservoir and drip tray were checked
  • Steps already tried

Does the leak appear around the reservoir?

Run a brew cycle and watch where water appears. Around the reservoir: suspect seating or overfilling. From the drip tray or brew chamber: suspect overflow or needle seal.

Run a brew cycle and watch where the leak appears. Around the reservoir: suspect reservoir seating or overfilling. From drip tray or brew chamber: suspect drip tray overflow or exit needle seal. Good: you know the location. Bad: leak is unclear—dry the area and run again to confirm.

Yes No

Is the reservoir seated and not overfilled?

The reservoir must click or sit flush. Do not fill above the max line.

Remove the reservoir and reinstall it firmly until it clicks or sits flush. Confirm the reservoir is not filled above the max line. Overfilling causes overflow. Seated and not overfilled: reseat firmly and run again. Overfilled: fill to max or fewer cups. When you brew, you should see no water seeping from the reservoir.

Yes No

You can change your answer later.

Reseat and adjust fill

Reseat the reservoir firmly. Fill to the max line or fewer cups. Run a brew cycle. The leak should stop if seating or overfilling was the cause.

Done

Reseat and test

Reseat the reservoir firmly. Run a brew cycle. If the leak stops, the reservoir was misaligned. If it continues, check the reservoir for cracks or call a technician.

Done

Is the drip tray seated and the cup large enough?

Brewing into too small a cup or a misseated drip tray causes overflow.

Confirm the drip tray is fully seated and the cup stand is in place. Use a mug that fits under the spout and is at least as tall as your brew size. Seated and cup OK: reseat and retest. Cup too small: use a larger mug. When you brew, you should see coffee flowing into the cup, not onto the tray.

Yes No

You can change your answer later.

Reseat drip tray and use larger cup

Reseat the drip tray and cup stand. Use a mug that fits under the spout. Run a brew cycle. The leak should stop if overflow was the cause.

Done

Clean needle and descale

Unplug and cool the machine. Lift the K-Cup holder and clean the exit needle with a paper clip or Keurig cleaning tool. Run a descaling cycle per your model's instructions. Rinse with plain water. If the leak continues, inspect the reservoir for cracks. A cracked reservoir cannot be reliably repaired—replace the unit. If water pools under the base, call a technician.

Done

Frequently asked questions

Why does my Keurig leak?
Common causes: reservoir not seated or overfilled, drip tray overflow from brewing into too small a cup, a clogged or damaged exit needle seal, or mineral buildup blocking the water path. Pinpoint where the leak appears to narrow it down.
Can I fix a Keurig leak myself?
Yes. Most leaks are fixable by reseating the reservoir, adjusting fill level, checking the drip tray, and cleaning the exit needle. Run a descaling cycle if mineral buildup is suspected. If the reservoir is cracked or water pools under the base, replace the unit.
When should I replace a leaking Keurig?
Replace the unit if the reservoir is cracked, water pools under the base after checking all components, or the leak persists after reseating, descaling, and cleaning the needle. For many Keurigs, replacement is more practical than internal repair.
