The answer to 'why is my garbage disposal making gurgling noise' is that the garbage disposal is likely clogged or has a blockage in the drain line. This gurgling sound is a common symptom of a clogged or blocked disposal, as the water and waste are unable to flow freely through the system.
Some common causes of a gurgling garbage disposal include food debris buildup, foreign objects jammed in the disposal, or a clogged drain line. The gurgling noise indicates that water is having trouble draining, which can lead to unpleasant odors and potential water backups if not addressed.
