I find washing the dishes is all about context, needs, energy situation. I rented property in the past and had dishwashers sometimes with more or less success. Now I live in a tiny home on wheels with solar power and got married to a man that does not do the dishes or cook. I tried for 3 years (or more) to train him to do the dishes but it was not working, to the extent neither of us would give up our definition of ”fair” and it was stressing me every single day. So we bought a dishwasher used online, which was a disaster for the batteries as it used a lot more electricity than it was supposed to and it turned out to be a waste of natural resources, money and time.
Then we bought an energy Aplus efficient dishwasher and that has been a wonderful success. Not only uses 8 liters of water per load, but it uses very little electricity in the eco setting which is 3.5 hours. However, living in the outskirts of Stockholm, Sweden, the winters are very dark and cloudy. Those days I do the dishes by hand, it all falls very much on me, but it is doable so far. Water comes from the rain and when frozen temps, from a well. I do not have running hot water and heat my home and cook in the winter with a wooden stove, (also super efficient stove but not a rocket stove), and I heat water for coffee in a gas stove.
In my case and due to the extremes between summer and winter, I find that I need several systems for different times and needs. It is perhaps more difficult to achieve self sufficiency than in a milder climate and it takes longer time, uses more space that is premier in my tiny home, but it is important to keep in mind not all dish washers are the same, some are evil and some are very well designed, not all situations are the same, not all cultures are the same, same with needs, etc.
I am happy with the solution so far, specially when I think it is free to do the dishes when the sun is shining! (yes it is not really ”free” as the set up costs) but I enjoy this solution in my particular case, including the hand washing from time to time.
