LG's washer recall: 457,000 machines whose drums could come loose

An unbalanced load could shake an LG top-loader until its drum came loose. 457,000 machines recalled after 343 vibration reports, 187 with property damage.

What happened

From April 2010 to December 2012, LG sold top-loading washing machines — models WT5001CW, WT5101HV and WT5101HW, plus Kenmore Elite models 29002, 29272 and 29278 sold through Sears and Kmart — for $899 to $1,099. The design had a failure mode: an unbalanced load could make the machine shake excessively and the drum come loose during use, risking injury to consumers and property damage to the surrounding area.

The reports accumulated: at least 343 reports of machines vibrating excessively, at least 187 involving minor property damage, and one minor injury. The affected models were manufactured in South Korea between February 2010 and November 2011. On December 18, 2012 the CPSC announced recall 13-073 covering about 457,000 units.

The remedy was a free in-home repair — LG or Transform (for Kenmore brand products) would fix the machine at the consumer's home — plus supplemental information for the owner's manual and a new caution label for the washer. Consumers who had observed their machine shaking excessively were told to stop using it, and that waterproof items such as mattress pads increased the chance of an unbalanced load.

Why it happened

  • A design that let the drum come loose under unbalanced loads shipped for 32 months — the 343 vibration reports were the field test that no lab test caught.
  • The recall fixed machines in homes for free — 457,000 in-home repairs is the price of a failure mode discovered after sale, not before.
  • LG's name on the recall did not spare Kenmore Elite — the same platform sold under two brands, so one design flaw recalled two brand names.

The lesson

LG's washer shipped 32 months before 343 vibration reports became recall 13-073; 457,000 machines then needed free in-home repair. Unbalanced loads are a use case, not an exception.

Aftermath

CPSC recall 13-073 (December 18, 2012) covered about 457,000 top-loading washing machines: LG models WT5001CW, WT5101HV, WT5101HW and Kenmore Elite models 29002, 29272, 29278, made in South Korea between February 2010 and November 2011. Sold at major retailers nationwide from April 2010 to December 2012 for $899-$1,099, the machines had generated at least 343 reports of excessive vibration, 187 with minor property damage, and one minor injury. Owners were told to stop using machines that shook, and to contact LG for a free in-home repair, a manual supplement and a new caution label.
