I have a LG Intello Dishwasher. About a month ago it started 'freezing' in mid-cycle and later shutdown by itself . If I start it up again, I can press any button and only get a 'ding-ding' sound. I would then leave it till the next morning and it would work fine, completing the cycle. Now since yesterday not even the 'leaving till next morning' is working, I only get the 'ding-ding' sound when any of the buttons are pressed. Any ideas on whats wrong and how it can be fixed??:confused:
