Sorry to be late to this party, and I appreciate that you've probably bought a new machine by now.
However, I'm astounded to hear of someone who has a Dyson washing machine - firstly because they were so unpopular anyway, and secondly because they were so problematic and broke down a lot (hence why production was stopped as it was just too expensive to build and maintain them).
I worked in an electrical department when the Dyson washing machine was launched in 2001. With an entry price of £899, it was more than double that of a decent regular washing machine - they were around the £400 mark, but you could still by washing machines for half that.
Unfortunately, the massive price tag, the unknown reliability of Dyson washing machines, and the fact there was a lot of purple colouring in the design, all went towards customers being unwilling to buy these washing machines.
The main advantage of the Dyson washing machine was that it could wash laundry really quickly, thanks to its split-drum which had a rear part turning one way, and a front part turning the other. However, while Dyson made a lot of noise about this benefit, they never really told consumers that it was doing a proper and thorough wash really quickly. This was a massive problem for those of us whose job it was to sell the machine, because pretty much every customer I spoke to noted that all other washing machines had some sort of quick-wash option / facility on them somewhere. The fact that this wouldn't be a full size and / or proper wash seemed to be neither here nor there...and for £899 on unknown technology, customers were continually looking for ways to talk themselves out of buying a Dyson.
As it was (and not withstanding your success with a washing machine that must be at least 20 years old), reliability was poor, and the two drums which turned in opposite directions proved to be a real nuisance, so much so that Dyson's answer to the problem was to get their engineers to visit a faulty washing machine to reprogram it so that the drums only turned in the same direction. As before, I'm astounded yours has lasted as long as it has.
In conclusion, I can tell you (having replaced my washing machine quite recently and did a lot of reading about them, having once been in the trade) there's nothing that's going to offer you the same capacity, performance, and speed of a Dyson as they were unique. I've purchased an Ebac which I am really, really pleased with. It has enough bells & whistles to make it adaptable enough to get great washing performance, but is still much more basic than the machine I had before, which I quite like as my previous washing machine was complicated beyond all description. My Ebac does a 10KG wash at 60'C , on a proper cotton cycle, with extra rinse and intensive option, in just over 2 hours. I am astounded at how clean the laundry is when I take it out.
HTH.
