Dishwasher has a bad smell, musty or rotten odor inside even when empty.

Safety first: Allow the appliance to cool before cleaning.

• Thorough cleaning: Remove and clean all filters, spray arms, and the sump area. Remove any trapped food or sludge.
• Check drain hose: Ensure the hose is installed correctly with no low spots where water can stagnate.
• Run cleaning cycle: Use a dishwasher cleaner or a cup of dishwasher-safe descaler on the hottest program.
• Leave door ajar: After cycles, leave the door slightly open to allow the interior to dry and prevent mold growth.

Regular maintenance washes will keep odors under control.
