False advertising

I purchased a Samsung washing machine and all literature says the water usage is 39 to 53 litres per cycle. This is not true. On the Super Eco Wash cycle which one would assume would be the most efficient from a water and electricity, the machine actually uses 180 litres of water. In my opinion the advertising is completely misleading as it does not exclude the Super Eco Wash. Furthermore, on most cycles, the machine takes almost 3 hours to complete a cycle. My faith in Samsung is dwindling.
