Dishwasher Bad Odor

Why a Dishwasher Smells Bad

A dishwasher that smells musty, sour, or like rotten food between cycles is almost always trapping standing water or debris somewhere it can't drain away. Food particles caught in the filter, positioned beneath the lower spray arm, decompose over days between cycles and are the single most common source of dishwasher odor. A partially clogged drain hose or drain pump leaves a small amount of water sitting in the bottom of the tub after every cycle, which turns stagnant and starts to smell within a day or two. A worn door seal that traps moisture along the gasket creates a damp environment where mold and mildew take hold. A clogged air gap on installations that have one restricts drainage and lets water sit in the drain line longer than it should.

A technician inspects and cleans the filter, checks the drain hose and drain pump for partial blockages, examines the door seal for mold or mildew buildup, and clears the air gap where applicable.

Diagnosed by Certified Technicians

Checking the filter, drain hose, drain pump, and door seal isn't guesswork: every technician holds NASTeC certification in appliance service and repair, with training from MiraCosta College's Technology Career Institute or San Diego College of Continuing Education (SDCCE) built on hands-on repair fundamentals under founder and Master Appliance Repair Technician Francisco Ortega, who has led the company since 2006. That standard is why every dishwasher bad odor repair carries a 90-day parts-and-labor warranty under our licensed and insured guarantee.
