I bought this LG dishwasher back in August 2023. It was great while it lasted. Saw no problems brewing in the background for 10 months. Then, without notice, it quit working.  No advanced notice that a problem was brewing, but in July, it failed to start.  I have a tech to put in a new mother board to get it working again.  This will be in late August. Luckily for me, it’s still under the 12 month warranty.  Why did it break down?
