Why does your Keurig make loud noise while brewing?

A Keurig can make loud noises while brewing due to several factors, including water being forced through the coffee grounds, which can create pressure and turbulence. Additionally, air bubbles trapped in the system can cause gurgling or rattling sounds. If the machine is not descaled regularly, mineral buildup can also contribute to increased noise during operation. Lastly, the brewing mechanism itself may create mechanical sounds as it activates and cycles.
