If your wash cycle is taking a long time to complete, or if there is an error message, it may be because the washer is off balance or overloaded. Wait until the cycle has completed before attempting to open the door. Try rearranging items inside the machine, or removing bulky items, and manually re-centering the tub. Then, re-run the cycle.
Clothes need room to move around with the water and soap to get clean – especially with new, high-efficiency washers. That’s why you should only fill the washer drum three-quarters of the way full. Overfilling can cause problems with the washer and potentially damage your clothes.
