In Australia you're not required to keep the packaging, and the company you bought it from must cover your shipping costs. This would constitute a Major Problem[1].

I suspect the company would just respond “the dishwasher is working fine the owner just refuses to enable features as per the manual”.
In 10 years that appliance may not connect to your wifi if the scheme has changed e.g. 2.4Ghz is dropped or something.
I read Australia<snip>Major Problem, and I immediately had the Koxbox track pop into my head. Naturally, it's easiest to find it on YT[0]. I never did take the time to look up where the sample came from, not what the full audio would say. I just assumed that Australians dutifully ignored it when heard as much as 'murikans ignored the FBI warnings at the head of VHS tapes--later DVDs.
