I'm not an appliance repairman but I also hate paying someone to do things I'm capable of so when my LG dishwasher started giving an error code "AE" I decided to fix it myself.
Fixing it was pretty easy - the hard part was figuring out exactly what had to be fixed and what part to order for the fix. It took probably 4 hours to diagnose and about 20 minutes to repair.
Hopefully this will help someone else shorten those first 4 hours.
