This was all helpful. What would we do without online help sources? Here we are in the midst of the pandemic & I put in a load, but it stopped with 2 minutes left to spin & displayed the dreaded DL/F code. I tried to cancel & reset, but the door remained locked & it would not reset to a new cycle; it just kept ticking, so I cancelled. This happened 3 times. Because my machines are stacked, it would be difficult for me to access the top panel, so after reading all the above comments, I decided to try the most noninvasive response & unplugged the washer. Let it sit overnight, hoping it would reboot. Sure enough, I plugged it in this morning & set it for a quick rinse & spin cycle; it finished the cycle & the door unlocked. Hope it will continue to work until the pandemic has subsided & it is safe to call for a maintenance check up.
