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].

That is a really good system you have over there.
I suspect the company would just respond “the dishwasher is working fine the owner just refuses to enable features as per the manual”.
Take them to court then! Get a group action or just small claims it. Do a CC charge back. They really can't deliver garbage.
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.
