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.
Probably because your dishwasher wasn’t engineered to work with powder detergent. I bought a Bosch dishwasher a few years ago and I read the manual where it specifically stated that even though it supports powder and liquid detergents it was designed to work with dishwasher tabs so that’s what they recommend.
I can’t help but wonder if people buy a new dishwasher–made for a completely different kind of cleaning substance–then continue their old (powder) ways and wonder why it doesn’t work as well as the old one.
Note: My Bosch dishwasher’s manual had notes in it about powder like, “if you’re going to use powder don’t use the ‘Auto’ mode…” and instead you should follow their instructions in regards to things like pre-rinse and how long you should wait before running the dishwasher (like, with powder I think the goal was to make sure everything stays wet before starting but I forget).
