I don't mean to make out that Indesit/Hotpoint don't
There are machines on the market which perform worse, my Mum's Whirlpool for instance leaves a bit to be desired on the wash front, and you say your current Haier isn't too great from that perspective.
It's just that their not the best either, from my experience the only thing that can wash better than a Zanussi is a Miele. All these A-G ratings may have improved the performance of machines on the whole compared to before their introduction, but it's not as if all machines which are A rated wash well.
I wonder if you could explain a bit more what you mean by "the motor is starting to go" on the Haier? It could be a cheap and easy fix, if the motor is sparking, making a "crackling" noise and/or the drum struggles to tumble, dosen't tumble, 9 times out of 10 thats just the carbon brushes, a very cheap, very easy and very common repair on any machine with a brush motor. It may even be that there's nothing wrong, I've thought many times that one of my machines was about to need repair because of strange noises, but as suddenly as they have started to happen, they stop and all is well from then on.
Don't give up and buy a new machine when there may be no need. "If it ain't broke, don't fix it" Is my motto.
