Hi Alioops,
I know you posted this a few days ago so you have probably already made a decision but we had a Dishlex which lasted us 10 years. We replaced it last year because the motor went in it but apart from that we had no trouble with it. My sister and a friend also have the Dishlex and they are happy with them as well.
I don't know anything about the LG.
When our dishwasher died it was full of dirty dishes so DH and I had to hand wash everything in it which took ages. The next day DH came home with a new dishwasher and had it installed before dinner that night. LOL!!!
