Aren't all washed cycles the same time? Can't you just use a timer? That's what I do. My washer always takes 44 mins
No, not at all. It's not really possible unless you're using an extremely basic washer with no spin (Or a very poor spin) cycle. A lot of the reason washers are terrible at estimating how long a wash cycle is going to be is because they spend a variable amount of time balancing the clothes before the spin cycle.
