Samsung Electronics Co Ltd said it was working with a U.S. consumer product safety regulator to address safety issues related to some of its top-load washing machines.

Samsung acknowledged Wednesday that some of its top-loading washing machines, “pose a risk of personal injury or property damage.”

Already reeling from a global recall of at least 2.5 million Note 7 smartphones the electronics giant told media that itwas in “active discussions” with the U.S. Consumer Product Safety Commission (CPSC) to address potential safety issues of some of its top-load washing machines manufactured between March 2011 and April 2016.

Samsung released the following statement, including a safety warning, on their website:

Samsung is recommending that consumers with affected models use the lower speed delicate cycle when washing bedding, bulky or water-resistant materials. There have been no reported incidents when using this cycle.[/su_quote]

ABC News reported that 21 people submitted cases to the CPSC since early 2015 saying that washers exploded or blew apart. One customer in Texas said the explosion went through the wall of her garage. Samsung is also facing a class-action lawsuit in New Jersey.
