Causes and checks
The lint filter is not cleaned properly. Source: Troubleshooting: Performance, p. 53
- Clean the lint filter before every load. See Clean the lint filter.
- Hold the clean filter up to a light to see whether it is dirty or clogged. With high-lint loads it may be necessary to clean the filter during the cycle.
The laundry is not sorted. Lint producers such as a fuzzy white cotton towel should be dried apart from lint trappers such as black linen pants. Source: Troubleshooting: Performance, p. 53
- Dry lint producers separately from lint trappers.
Static in the clothes holds lint. Source: Troubleshooting: Performance, p. 53
- Use a fabric softener as its manufacturer instructs, and adjust the settings for a shorter drying time or use Sensor Dry cycles. Overdrying builds up static.
The dryer is overloaded. Source: Troubleshooting: Performance, p. 53
- Divide extra large loads into smaller loads.
Tissue or paper was left in pockets. Source: Troubleshooting: Performance, p. 53
