LOS ANGELES (CBSLA.com) — Samsung is recalling an estimated 2.8 million top-loading washing machines over tops the company says can unexpectedly detach from the chassis during use.

The Consumer Product Safety Commission says the recall involves 34 models of Samsung washing machines with mid-controls or rear-controls.

The machines were sold at major retailers like Best Buy, Home Depot, Lowes and Sears between March 2011 and Nov. 2016 for between $450 and $1,500. Consumers were recommended to check their machines’ model numbers and serial information on two labels on the backs of the machines to see if it’s one of the serial numbers under recall.

Consumers can opt for a free in-home repair and one-year extension of the manufacturer’s warranty, a rebate towards the purchase of a new Samsung or other brand washing machine, along with free installation of the new unit and removal of the old unit, or a full refund for owners who bought their machines within the past 30 days of the recall announcement.
