Washer Leaks During Rinse Cycle
Problem: Washer leaks water during the rinse cycle even after cleaning the lint trap and checking water hoses for leaks.

Solution: If a leak is going to happen with a front loader, it is most often during the rinse cycle because more water is used at that time. The cause is most likely a leak or hole in one of the interior lines. It could be a puncture/hole in either the drain hose or the soft, black bellows hose next to the drain pump assembly. If you need a user or repair manual, you can find it here.

Washer Stops During Spin Cycle
Problem: Washer stops during the spin cycle and becomes off-balance. The spin cycle will complete after clothes are rearranged.

Solution:

Run a diagnostic test to see if any error codes appear. The failure to complete the spin cycle can be caused by a slow drain and that code will appear.
To correct the slow drain, open the bottom panel of the washer housing. You will see a plug on the lower right. Have some towels ready to catch a gush of water and remove the plug. Clean out the filter. You may find lint, coins or buttons are obstructing the flow into the pump.
Never overload the washer. Take time to read the manual when you are not in a hurry to learn which cycle to select for different size loads.
Samsung Washer Will Not Start
Problem: Washer will not start even though the display says it is ready to begin the cycle.

Solution: If the washer is receiving electrical power and everything else looks good, start by cleaning the contact points of the door latch with a bit of rubbing alcohol on a cotton swab. Even though it indicates that it is “locked”, there must be full contact. If that doesn’t work, a technical manual will help you put the washer into diagnostic mode to better determine if you have a mechanical, computer or electrical problem.
