>>>" I really just want to be able to select a hot wash and know the water is hotter than 104. I need to research if the compact Electrolux can do that, "<<<
It does seem to be able to do that as far as I could tell from checking out the compact Electrolux recently. While it was difficult to find much in the way of in depth reviews that got into the details like actual temperatures, I did find a Q&A response from Electrolux Support on the Home Depot webpage for the EFLS210 where the company responded to a question like yours. The responding rep said:
"The temperature of the cold water when it enters the washer will be whatever temperature you have your home set to. On an Energy Star cycle [warm setting?] it will be around 100°F, on the regular cycle [hot setting?] it will be around 120°F, and on a sanitize cycle it will be around 152°F."
Because this seemed unclearly incomplete, I called the Electrolux customer support number to get a more detailed response. I happened to get a rep who actually was familiar with the model. I was deluged with detailed info. I was only able fully understand what I was told by looking at the "cycles and options" chart on page 15 of the "Operating Manual" that I had downloaded. I'd recommended checking out the manual if you haven't already downloaded the pdf.
The rep started by telling me that an "Energy Star cycle" was the "normal" and/or "whites" cycles using the default temperature setting of "warm" with the default option of "eco friendly" engaged. That should produce a wash temperature of "around 100°F." When you switch off the "eco friendly option," the warm temperature should be mixed a little higher, around 104°F. (This assumes that the water arriving at the hot inlet is at or above 104°F. )
If you select the "hot" temperature option for these cycles without switching off the "eco friendly" option, it seems that the wash water does not get much hotter than the "warm" setting. (Dunno if that might also be true for your present LG WM4370, but maybe something to look into?)
Anyway, when the "eco friendly" option is disengaged on the compact Electrolux, the rep said that the Automatic Temperature Control (ATC) is supposed to mix the intake water to produce 120°F wash water temperature --- provided your hot water line is delivering water to the washer at or above 120°F. (The rep gave the standard advice that "you might want to run the hot tap on a nearby laundry sink to be sure that some of the cooled standing water has been purged if your laundry is any distance from the water heater.")
The Electrolux rep further explained that the washer's "steam" option is a recirculation pump that pairs with the on-board water heater to keep "hot" washes hotter for a longer time. When you choose the "heavy duty" cycle or the "normal with steam" cycles, and bump the temperature selection to "hot," and deselect the "eco friendly option" when using the "heavy duty" cycle (the "eco" is automatically deselected when you choose the "normal with steam" cycle), the washer should maintain a wash water temperature around 120° for most of the wash cycle before cooling down towards the end of the wash time. The subsequent rinses are with cold water.
The rep was a little unsure of how the sanitize cycle worked except that the onboard water heater heats the wash water up to 152°F and that the cycle takes almost two hours to run. (From posts by owners in various places, it seems that the Sanitize cycle takes about 1 hr. and 52 min.)
After ingesting that passle of info overload, I also stumbled into some discussions of the EFLS210 and its immediate predecessor model (EFLS20Q) here and at Automatic Washer.org. (AFAIK, the prior 20Q differs from the current 210 mainly in having a couple of fewer cycles.) For searching here and at AutomaticWasher, I found that a poster named Practigal seemed to have the most in-depth info. You might include that screenname in a search string when looking for discussion threads.
