Samsung discontinued its Galaxy Note 7 smartphone, which was prone to catching fire, last month. But the company's safety problems have not ended there. The manufacturer and a product safety regulator on Friday announced a recall for 2.8 million washing machines in the United States.

The number of washing machines recalled, which includes 34 models of Samsung's top-loading washers, exceeds the 1.9 million Galaxy Note smartphones Samsung and the U.S. Consumer Product Safety Commission recalled last month.

The safety commission said the affected Samsung washing machines had tops that could detach from the chassis during use, "posing a risk of injury from impact." Samsung said this could occur when consumers used a high-speed spin cycle for washing water-resistant clothing or bulky items, including bedding.

"Our priority is to reduce any safety risks in the home and to provide our customers with easy and simple choices in response to the recall," John Herrington, a general manager of home appliances for Samsung Electronics America, said in a statement.

The safety commission said Samsung had received 733 reports of washing machines experiencing excessive vibrations or the tops detaching. In addition, there were nine reports of related injuries, including a broken jaw and injured shoulder, the commission said.

Samsung said it was moving quickly with the product safety commission to inform consumers of their options. The company said consumers could choose an in-home repair, in which the top of the washer would be reinforced. The second option for customers is to receive a rebate that can be applied toward buying another Samsung washing machine.

Samsung said it would offer refunds only to customers who bought a recalled washing machine in the last 30 days.

The safety commission has listed the 34 affected washing machine models, which were sold from March 2011 to November of this year. Customers can also enter their serial numbers at Samsung's website to see if their machines are part of the recall.
