I'm trying to calculate exactly how much water is spent per washing machine use (medium water-level with a soak-wash-rinse-spin cycle).
On the last page of the manual of my washing machine (Samsung - WA6550B9), it states that the "water usage" is 164 litres. However, a tub of water at its "high water level" is only 56 litres:
Why is the "water usage" stated to be 164 litres?
Even if it's a soak-wash-rinse-spin cycle, wouldn't it use approximately two tubs of water? Yet 56 litres × 2 is far from 164 litres.
How do the numbers add up? What exactly is the 164 litres of water usage referring to?
