In a video by @Techconnectify@mas.to, 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.

@JWBananas

And truthfully, what I messed up in the first video was not getting into the nuance of water hardness and detergent amounts.

People who follow the directions on powder to "fill cups completely" are going to be in for a rough time if they have soft water. I didn't get into that, so people started using powder, used too much, and had worse results.

So I went further, showed how you can actually get away with very little detergent, which imo is yet another reason to prefer powder.

@JWBananas So yeah, honestly I feel like you're missing most of the context in those videos.

I never said pacs don't work - I said that I suspect they've led to a lot of dishwasher dissatisfaction, made an argument as to why, and backed that up with a demo of the pre-wash and how, with no detergent in there, more stuff was left on the plates. That then was the starting point for the main wash cycle, and I figured that difference would speak for itself.

If it didn't, then /that/ was my mistake

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.

[–] Zagorath@aussie.zone 1 points 1 year ago

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.
