Washer Smells Like Rotten Eggs? 5 Causes and Fixes

If your washer smells like rotten eggs, it’s usually caused by bacteria buildup, mold, or trapped residue. Here’s how to fix it quickly.


Common Causes

  • Bacteria buildup
  • Mold in the drum or gasket
  • Detergent residue
  • Standing water
  • Clogged drain

1. Run a Hot Cleaning Cycle

Run an empty cycle with hot water and vinegar to kill bacteria.


2. Clean the Rubber Gasket

Front-load washers often trap moisture in the gasket. Wipe it clean and dry it.


3. Use Less Detergent

Too much detergent can leave residue that leads to odor.


4. Leave the Door Open

Let the washer dry out between cycles to prevent mold growth.


5. Clean the Drain Filter

Remove debris from the filter to prevent stagnant water buildup.


When to Call a Technician

If the smell persists, there may be a deeper drain or plumbing issue.
