How do I force a factory reset?

How to force a factory reset depends on device type, but general method for Samsung appliances and electronics involves using button combinations or power cycle to restore factory defaults and erase custom settings. For Samsung washing machine factory reset, turn on washer, press and hold Temp and Delay End or Spin and Soil Level buttons simultaneously for 3 seconds to enter service mode, then press Power, or unplug washer for 10 minutes to clear memory, then run calibration cycle with empty drum by pressing Temp and Delay End then Start. For Samsung refrigerator factory reset, unplug for 5 to 10 minutes or hold Power Freeze and Power Cool for 10 seconds. For Samsung phone force factory reset when locked, turn off phone, press and hold Volume Up and Power buttons to enter Android recovery mode, use volume keys to select Wipe data factory reset, press Power to confirm. For Samsung TV, hold Power button on remote until TV restarts, or go to Settings General Reset.
