Product review (3 stars): It wasn't a bad machine, just bad upbringing
I didn't buy this through Amazon. It came with the house, new, when we moved in 3.5 years ago. It actually ran very well for the last 3+ years. Bone dry with rinse aid and cleaning pods (vs. liquid detergent). Even when I did the top rack with nothing but plastics (tupperware & kids sip-cups, plates, rubber/silicone-coated BBQ utensils), I could use one, maybe 2, paper towel to dry off any residual water/condensate still present. No detergent residue was ever present, either. In the last couple of months, just beyond the warranty period, and the only way things get dry is by leaving the door open for several hours after the cycle (pick a cycle, any cycle) is complete so everything can air-dry. Half the time, we still need to wipe everything down because detergent/hard-water residue.

It wasn't a bad machine, just bad upbringing, I guess. Since it's been relegated to the designation of a "really expensive drying rack", I'm going for broke and trying out various DIY fixes to see what works. The electronics all seem to be in order, based on my trusted multimeter, so I'm focused on cleaning the heating element with vinegar since hard-water scaling is about the only obvious issue can think of to be causing the inefficient heating/drying capability after all these years. I'll keep y'all posted if that works. I can't say it'll mean much to those who say their machine didn't work as expected/advertised from the start, but it may help anyone who had a machine that was good for a while, but just isn't working like it used to.
