Tromm is the trae name for washers and dryers manufactured by LG Electronics. They are designed and often sold in pairs and have many functions, such as child lock, delayed wash timers, and multiple spin speed selection. All LG Tromm washers are front-loading and feature a direct drive motor which eliminates belt drive of the wash drum, a design which extends motor service life and allows LG to extend a seven-year warranty on the motor drive mechanism.
