LG WT7300 top loader washing machine. Over past year has been not powering up sporadically and requires hard reset. When unplug then plug it back in sparks sometimes (and popping sound). This problem has been now occurring everytime after use and sometimes takes several hours unplugged before it will power on. We have replaced the outlet thinking it was an issue with this, however, continues to spark and power off with new outlet (which works fine when other small appliances are plugged in). After researching online this seems to be a common problem with this series of LG washers. LG is unable to offer a solution from what I have seen.
