Yes it can be resealed and still be ipx68 (water dust resistant. You must use the right tools when disassembling and during reassembly. Use heat gun or hot air station to heat the back glass just to when you can't touch it using playing cards and thin metal pry tool slowly break adhesive seal. Remove battery When re assembling the phone be sure to use a water resistant adhesive. 3M makes adhesive and tapes that can reseal back The biggest thing is heat back glass and and adhesive slightly prior to install then place paper or something over back to protect it then set something heavy on it I used wood clamps with adaptors to keep tight equal pressure on entire back let it sit like that for 2 hours and it will be resealed against dust and water. A little more extensive and cost more but but just sticking back back on using old adhesive will not reseal correctly
Your code Sd is most likely related to 'slow drain', which can be the pump in the machine or the drain behind it. Check to be sure the drain is clearing quickly enough and if so, have the pump on the washer checked or remove from washer and clean it out. In the meantime, if you hit cancel and let it sit a bit then hit start, it should take right off and finish the cycle. Hope this helps!
