What to Check First
- Clean the Detergent Dispenser If using cold water for washing, the detergent may not completely dissolve, resulting in buildup and/or odor. Note Dispenser type and location will vary depending on your washer model.
- Clean the Door Gasket The door gasket can collect foreign objects such as lint or hair strands from washing.
- If not removed, those foreign objects could cause gaps or retain water causing mold and odor to form.
- Wipe it with oxygen-based bleach and leave the washing machine door open to dry.
- Remove Foreign Objects From the Drain Pump Filter A clogged drain pump filter can lead to poor draining, causing water to remain in the drum leading to odor over time.
- Run a Tub Clean cycle Detergent residue can buildup around the drum and door gasket causing odor to form.
- Use a tub cleaner to help breakup the detergent residue and eliminate odor.
- It is recommended to perform the tub clean cycle once a month to prevent odor / buildup from forming.
- Improper usage of detergent or neglecting routine maintenance on the washer can lead to the development of odor or buildup. To address this problem, it is important to adhere to the recommended detergent guidelines and perform regular maintenance tasks.
- If using cold water for washing, the detergent may not completely dissolve, resulting in buildup and/or odor.
Why This Can Happen
