How to calibrate a samsung washer model

There was incorrect instructions online on how to enter into calibration mode with the Samsung washer model WA50R5400AV/US. I tried and tried things until I found out how to. No one online was right. They said to empty machine, power on then hit temp and start together this is incorrect. You have to hold down delay end and Temps at about the same time, but I did have more luck hurting delay end then pressing Temps. Then it said c6 you have to hit start to start the process. It takes about 2 minutes and then it chimes to let you know it has finished the procedure. I got this helps someone.
