Final Installation Check and Power Test
After the washer has been installed, use the final check below to confirm that the power connection, water supply, spinning, draining, and leveling are all working properly.
Connect to power - Plug the washer into a 120 V, 60 Hz grounded 3-prong outlet. - Make sure the appliance and outlet are positioned so the plug is easy to reach.

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.
