I had a control board and main board replaced in my dishwasher. The dishwasher was just under 2 yrs. old. After the control board and main board were replaced still under warranty, it quit working within an hour of having the new parts installed.
From the time I reported the problem to LG and the servicer fixing it, it was 3 months. I am now out of warranty for the control board and main board to be replaced under the warranty. Obviously there is major defects with the manufacturing of this product.
Do not buy this dishwasher. I was told by the servicer of LG the appliances are NEVER replaced.
