Setup and Installation

Connecting Water and Drain Hoses

Electrical Connection

Plug the washer into a grounded 120V, 60Hz, 15 Amp circuit. Do not use an extension cord.

Leveling the Washer

Use a level to ensure the washer is perfectly level. Adjust the leveling feet at the bottom of the washer as needed to eliminate any wobbling.
