What should I do if the washer displays an 'Ofb' error code?

The 'Ofb' error code means the load is off balance. Open the lid, redistribute the load evenly, close the lid, and press START/PAUSE to resume the cycle. To help prevent off-balance issues, load items in loose heaps evenly around the washplate and avoid washing single large items alone — balance them with a few extra items. (Page 19)
