Used to be when the old appliance stopped working, and it cost too much to repair, or parts were no longer available, a new whatever would be in the works, and you'd go with the brand you had, that had worked well for over 10-15 or more years.
However today with the cutting corners, the increased cost of shipping, and the more complex design of appliances being built... longer running appliances are but past memories. Oft times, it's cheaper to fix, if parts are still available. also keep in mind that tech-work can be quite expensive.
So, with the above in mind, I usually go to a parts place, or phone a service company, and ask about an intended future buy and hear what they have to say about an certain brand. Usually they are up front, unless they are tied at the hip with a certain manufacturer.
Then there's independent test-types on "YouTube", but I take them with a bag of salt. Also, I ask neighbours/relatives/friends what they have, or see what the "pro's" online have to say about certain makes and read their "reviews".
I've found what is also important is if a "support" system in place if something goes wrong, and you have to deal with warranty. Plus, if service is available in my area!
Finally, really read what the warranty is all about, wherein who pays for what, and the possible cost of labour in having repairs done!
No matter what you buy, it's seems to be... a coin toss today. Even the techs will admit this. I've asked!
Bon chance
