Descaling & Maintenance
Keurig descale light won't go off — how to reset it
Scale builds up inside every coffee machine and eventually blocks the boiler and pipes. Run a full descaling cycle with Keurig's approved descalant every 2-3 months (or whenever the machine prompts it), then rinse with fresh water. If your machine refuses to descale, see our not heating guide.
Keurig descale with vinegar: is it safe?
Scale builds up inside every coffee machine and eventually blocks the boiler and pipes. Run a full descaling cycle with Keurig's approved descalant every 2-3 months (or whenever the machine prompts it), then rinse with fresh water. If your machine refuses to descale, see our not heating guide.
Power & Startup
Keurig coffee machine won't turn on
When a Keurig machine won't turn on, check the outlet, the power cord, and the switch first. Unplug it for 60 seconds and retry — this clears most temporary control-board faults. If it stays dead, the thermal fuse or power supply may need replacing; see our not turning on guide.
Water Flow & Pumping
Keurig error: brewing but no water comes out
If no water comes out of your Keurig machine, the tank may be mis-seated, there may be air in the circuit, or the pump inlet is blocked by scale. Reseat the tank, run a blank cycle to purge air, and descale if flow stays weak. See our water not pumping guide.
Coffee Quality
Keurig not brewing a full cup
Weak or watery coffee from a Keurig machine is almost always grind, dose, or extraction time: grind finer, use a correct dose, and make sure the brew lasts 20-30 seconds. Scale can also slow extraction — descale if the flow looks thin. See our not brewing guide.
Keurig Mini problems: weak coffee
Weak or watery coffee from a Keurig machine is almost always grind, dose, or extraction time: grind finer, use a correct dose, and make sure the brew lasts 20-30 seconds. Scale can also slow extraction — descale if the flow looks thin. See our coffee too weak guide.
Water Leaks
Keurig leaking from the bottom
Water leaking from a Keurig machine is usually a loose hose, a worn seal, or a drip tray that is not seated correctly. Dry the machine and trace where the water appears during a brew cycle — most leaks are repairable without a service visit. Full steps in our leaking water guide.
Reset & Recovery
How to reset a Keurig coffee maker
Most Keurig machines can be reset by unplugging them for 60 seconds, or with a factory-reset button combination listed in the manual. A reset clears error states, stuck menus, and most temporary faults — try it before any other repair. Details in our not turning on guide.
