Often, the presence of leftover food debris can cause unpleasant smells in the dishwasher.

Follow these steps to clean the dishwasher of any food residue:

1.4. Use a dishwasher-safe brush to scrub the interior walls, door gasket, and any other areas where food might accumulate.

Step 2: Clean the Filter and Spray Arms

A clogged filter and dirty spray arms can hinder proper water circulation, leading to a build-up of bacteria and unpleasant odors.

Here’s what you need to do:

2.1. Locate the dishwasher’s filter, typically found at the bottom of the tub. Remove the filter as per the manufacturer’s instructions.

2.2. Rinse the filter under running water to remove any debris or residue.

2.4. Reinstall the cleaned filter and spray arms back into the dishwasher.

Step 3: Check the Drain Hose

A clogged or improperly installed drain hose can cause stagnant water to accumulate and produce an egg-like smell. Follow these steps to inspect the drain hose:

3.1. Locate the dishwasher’s drain hose, usually found underneath the sink or attached to the garbage disposal.

3.2. Disconnect the drain hose and inspect it for any clogs or kinks.

3.3. If you find a clog, use a plumbing snake or a straightened coat hanger to clear the obstruction.

3.4. Reconnect the drain hose securely.

Step 4: Run a Cleaning Cycle with Vinegar

Vinegar is a natural deodorizer and can help eliminate lingering smells in your dishwasher. Follow these steps to run a cleaning cycle:

4.1. Place a cup of white vinegar on the top rack of the dishwasher.

4.2. Run a hot water cycle on the longest and hottest setting.

To address this issue, consider these steps:

5.1. Contact your water provider or conduct a water quality test to check for elevated sulfur levels.

5.2. If the water quality is the problem, installing a water filter or using a water softener might help.
