⚡ TL;DR — Quick Answer

Descale the Keurig boiler. Scale buildup causes cavitation noise during heating.

What Causes Making Loud Noise?

Keurig machines rely on K-Cup puncture needles and water flow sensors that are prone to clogging.

Step-by-Step Fix

Follow these steps specifically for Keurig machines:

  1. Descale the Keurig boiler. Scale buildup causes cavitation noise during heating.
  2. Inspect the pump bearings. On Keurig machines, a failing pump makes a grinding sound.
  3. Check the grinder burrs. Hard beans can jam the burrs and strain the motor.
  4. Place the Keurig on an anti-vibration mat. Noise from the drip tray resonance is common.

Frequently Asked Questions

Unusual noise is often air in the pump, a loose part, or scale rattling in the boiler. A Keurig grinder that stops usually has beans jammed in the burrs, an empty-hopper sensor triggered, or worn burrs. Empty and brush the hopper, run a few dry beans through, and never force the motor. Detailed steps in our Making Loud Noise guide.

When the grinder on a Keurig stalls, the first suspects are jammed beans and the hopper sensor. Clear the burrs with a brush, refill the hopper, and run a short grind. If it still stops, the burrs or drive gear may be worn — see our Making Loud Noise guide.

A silent Keurig grinder is most often a jam or a tripped safety switch. Unplug, remove the hopper, brush the burrs clean, and try again with a small amount of beans. Persistent failure points to the gear or motor — repair steps in our Making Loud Noise guide.
