A bad smell emanating from the dishwasher while it's running but not when it's opened or closed is likely related to the accumulation of food particles, grease, and other residues within the dishwasher. When the dishwasher is running, the water agitation and the high temperature can release these trapped odors, causing the unpleasant smell. However, when you open or close the dishwasher, the smell may not be as noticeable because the odors are contained within the closed space.
Here are some common reasons why a dishwasher might have a bad smell when running:
Food debris and residues: Over time, small bits of food and other residues can get trapped in the dishwasher's filter, spray arms, and other components. These trapped particles can start to decay and produce unpleasant odors.
Clogged drainage system: If the dishwasher's drainage system is partially blocked or not functioning correctly, water and debris can accumulate, leading to bad smells.
Stagnant water: In some cases, water might remain stagnant in certain areas of the dishwasher, promoting the growth of bacteria and producing foul odors.
Mold and mildew: The warm and moist environment inside the dishwasher can foster the growth of mold and mildew, which can cause bad smells.
Old and worn-out components: Over time, rubber seals and other parts in the dishwasher can degrade, allowing water and debris to accumulate in hard-to-reach areas.
To address the bad smell when the dishwasher is running, you can try the following steps:
Clean the dishwasher filter and spray arms regularly to remove any trapped food particles and residues.
Run a cycle with the dishwasher empty and use a dishwasher cleaner or a mixture of vinegar and baking soda to help remove odors and buildup.
Check the dishwasher's drainage system for clogs and ensure it is functioning correctly.
Keep the dishwasher door slightly open when not in use to allow air circulation and prevent mold growth.
Consider using dishwasher cleaning products specifically designed to tackle odor issues.
Inspect and replace any worn-out rubber seals or other components that may be contributing to the smell.
Regular maintenance and cleaning, along with proper loading techniques to prevent food particles from settling on dishes, can help keep your dishwasher smelling fresh and clean during operation.
