Using Detergent, Bleach, and Other Laundry Products
This washer uses an automatic dispenser drawer for many laundry products, but some products must go directly into the drum. For best results, use the correct compartment and do not overfill.
Before you add anything - Always use HE (High-Efficiency) detergent with this washer. - Follow the detergent, bleach, and softener manufacturer’s recommendations. - Use less detergent for soft water, light soil, or smaller loads. - Be extra careful with 2X and 3X concentrated detergents. Even a small extra amount can cause problems. - Never use more than the maximum amount recommended by the manufacturer. - Do not place or store detergent, bleach, or liquid fabric softener on top of the washer. These products can damage the finish and controls.

Your washer lets you customize many cycles after you choose the cycle. Each cycle starts with default settings, but you can change some settings using the modifier buttons.
Before you change settings - Repeatedly press the button for the setting you want until the correct indicator light turns on. - The LED next to the selected setting lights up. - The washer automatically adjusts the water level for the load size and fabric type for better results and efficiency. - This is a high-efficiency washer, so the water level may look lower than expected. That is normal, and washing and rinsing performance is not reduced. - Not every temperature, spin speed, soil level, or option is available on every cycle. - If a setting is not allowed for the selected cycle, the washer sounds twice and the LED does not light. - Always follow the fabric care labels on the garment.
