⚡ 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.
