Oh for sure. I mentioned my own requirements because I couldn't set why I'd need to spend a few hundred extra to save minus still a few hundred

That's the main reason that stops me from buying a Miele solar save dish washer. Like yes it uses so much less, and yes, it makes better use of my solar panels but also its a lot more expensive for what's realistically little gain (for me)

My D rated dishwasher uses 0.85 kWh per cycle. An A rated one uses 0.54 kWh per cycle. If you use it every single day, you're looking at a saving of 113.15 kWh in a year. In the UK, assuming April 2023 pricing that's a saving of £61.11 a year

When electricity was 15p/kWh, then you'd have to use your dishwasher multiple times a day for it to be cheaper. Assuming you're using it once a day, that's a saving of a mere £17 a year. Assuming also that it lasts ten years, I'd look to have spent £200 extra, max.

But again that is if I was using it once a day, which I'm not.
