Use a cottons programme, 40°C to 60°C, and a high spin for towels. Avoid overloading, too much detergent, and fabric softener build-up.

Clothes Still Dirty After Washing Machine

Dirty clothes after washing are usually caused by overloading, the wrong programme, too low a temperature for the soil level, poor detergent dosing, or a rinse/drain problem.
