Keurig Not Brewing: Pump, Needle, Scale, and K-Cup Problems

Quick Answer

A Keurig that will not brew at all (you press the button but nothing happens) is different from one that brews slowly or makes a partial cup. If nothing dispenses, the pump has air-locked or failed. Try priming the pump: remove the water reservoir, refill it, replace it, and press brew with no K-cup inserted. Repeat 3-4 times to force air out of the lines.

A Keurig that won't brew at all (you press the button but nothing happens) is different from a Keurig that brews slowly or makes a partial cup. If NOTHING dispenses: the pump has air-locked or failed. Remove the water reservoir, shake it, refill, reseat firmly. Press brew with no K-Cup to prime the pump. If water flows without a K-Cup but not with one: the entrance needle (top needle that pierces the K-Cup lid) is completely clogged. Use a straightened paperclip to clear the needle hole. If the Keurig makes noise but no water moves: the pump motor is running but the impeller is stuck from scale buildup. Descale with vinegar immediately. If the Keurig does NOTHING when you press brew (no noise, no lights): the power supply or heating element has failed. Keurig machines have a thermal cutoff fuse that blows if the heating element overheats - this is not user-accessible. K-Supreme and K-Cafe models show Error 2 when the flow sensor detects no water movement.

Frequently Asked Questions

How do I find my model number?
Check the inside of the door (front-load), inside the lid (top-load), or the back/side panel for a sticker with the model and serial number.
Is it worth repairing?
If the appliance is under 8 years old and repair is under 50% of replacement cost, repair is worthwhile. Check warranty coverage first.
Can I fix this myself?
Many repairs are DIY-friendly with basic tools. Gas appliances and sealed refrigerant systems should be serviced by professionals.
