Sounds like the drain pump is bad or blocked. Sometimes there are little kid socks or underwear in the pump. Best to replace the pump because even if it is blocked, sometimes they will leak after you remove the blockage.
I have some Crazy repairs...... Anyone else run into crazy situations?
My day started with a fridge that's not cooling properly,
I open up the freezer and quickly ascertain that the evap fan is not working but the inside of the freezer smells Fresh! Fresh like clothes straight out of the dryer.
I pull the back panel off to replace the evap fan and see that something is cuaght up in the fan. Low and behold its a stack of dryer sheets! After talking to the customer she claimed to like the smell so she wanted her fridge to smell like that and shoved the dryer sheets in there up at the top of the freezer section! Then ask do I have to pay for this? LOL hell yes!
The parts that are breaking on samsungs appliances are failing way too soon.
If you were using the correct amount of HE soap.
You need to disassemble the tub and see if the flange shaft is broken. You probably need bearings and maybe even an outer tub. Im not even sure if they sell the bearings separate from the rear tub.
There are 6 bolts that hold the flange shaft to the inner tub. To access the flange you have to remove the otter tub. The outer tub will open to the inner tub. You have to practically take the whole washer apart to remove the tub. The stator (motor) has a bolt into the rear of the flange. Take a lot of pictures. This is one of the harder repairs to do.
I would pull it apart and see whats broken. It may change your mind on repair.
