Won't Brew — handle, Add Water, scale, or clogged needles

When the brewer powers on but pressing brew does nothing, Keurig's documented causes are all user-correctable: the handle isn't pushed down securely, the reservoir is in an Add Water condition, scale buildup is restricting flow (the DESCALE light is the cue), or the needles are clogged. Double-clicking the power button resets a stuck brew. There's no pod-detection sensor or "control lockout" state documented on these brewers — if all brew-size lights blink simultaneously, that's a documented fault condition and Keurig says to contact Customer Service.

How to fix it

  1. Confirm the handle is pushed down securely until the size buttons flash
  2. Check the reservoir — refill to the MAX line and reseat it firmly if it's in an Add Water state
  3. Double-click the power button to reset a stuck brew, then retry
  4. If the DESCALE light is on, run the descaling procedure
  5. Clean the entrance and exit needles with a straightened paper clip if flow seems restricted
  6. If all brew-size lights blink simultaneously, contact Keurig Customer Service — that's a documented fault condition, not something more home troubleshooting resolves

Why it happens

Typical signs: Button presses do nothing · Size buttons not flashing / brew won't start · DESCALE light illuminated · All brew-size lights blinking simultaneously

  • Handle not pushed down securely The brewer won't start until the handle is fully latched and the size buttons flash
  • Add Water condition Reservoir empty, low, or not fully seated — refill to MAX and reseat firmly
  • Scale buildup DESCALE light illuminated — restricted flow until the descale procedure is run
  • Clogged needles Pod grounds restricting flow enough to prevent the cycle from starting
