In a video by @[email protected], Alec goes into a deep dive into the simplicity of his particular model, its shortcomings and variety of data logging tests in an attempt to fix them.
TL,DW: Very simple, cheap and ingenious design, with one compressor loop between the fridge and freezer in series. However, its temperature sensor is wonky and so the fridge is more affected by how long the compressor operates than the actual temperature itself. There is a signficant temperature differential between the top and bottom, fans on the exterior or interior could help but with the faulty sensor only made matters worse. With the controller replaced with a proper temp control unit the fridge functioned much better.
The other guy is totally unnecessarily being a dick, but is perhaps touching upon a good point.
The prewash stage might have a more effective result if some detergent is put in, but there’s no actual value in that if a full main wash without pre-wash detergent results in a completely clean load of dishes.
@Zagorath I see a lot of detergent products advertising “no pre-wash required” on their packaging, at least here in AU.
That’s probably referring to the fact that you shouldn’t prewash by hand before putting something in the dish washer.
It may also simply be inaccurate marketing.
Good (if rather rambly) video about it: https://youtu.be/_rBO8neWw04?t=505
He also touches on that prewash marketing in a second follow-up video to the above. It also discusses the value of rinse aid.
edit: ha, whoops. Just linked a pair of Technology Connections videos in a thread about Technology Connections. Didn’t realise where I was… Still, if you haven’t already seen them, they’re worth watching.
