Samsung, following the embarrassing setback from Galaxy Note 7 smartphone explosions, has another problem on its hands.

U.S. regulators have warned owners of certain top-loading Samsung washing machines of “safety issues” following reports explosions, CNNMoney reported.

The warning, without specifying the model, from the Consumer Product Safety Commission, covered machines made between March 2011 and April 2016.

The warning is followed by a federal class-action lawsuit against Samsung by customers who said their machines had exploded during use.

Customers in Texas, Georgia and Indiana all reported they were washing clothes when they heard a violent boom.

A woman from McAllen, Texas said that the machine “exploded with such ferocity that it penetrated the interior wall of her garage,” according to court filings. A woman in Dallas, Georgia, said it felt and sounded as if “a bomb went off.”

The lawsuit, filed in federal court in New Jersey, cites similar reports collected by local news and filed online with regulators. It also claims Samsung “has moved aggressively to collect and destroy all evidence of the defective machines” after they exploded.

Samsung said its customers “have completed hundreds of millions of loads without incident since 2011.”

Earlier this month, Samsung had decided to replace 2.5 million of its Galaxy Note 7 smartphones after reports of battery fires.
