John, unfortunately, that is very outdated material. LG did away with a temperature option containing a warm rinse about the same time WP did, if not before. Back in 2011 WP & LG both had steam generators and both firms eventually did away with that design about the sme time. The steam geneartor was far more effective than how steam is genrated now--just having a small pool of water in the sump/out tub area near the heater that causes wafts of steam to rise up from down below over the load. A lot of people argued with me over time because it didn't make sens for WP product seqence for steam to be regular wash phase, then drain, do a distribution speed spin, pause, add water to a resevoir near the top of the machine and dispsenser drawer, then spend 18-24 minutes heatng that smalll resevoir's amount of water into steam and shoots out into the tub (top left) over the load and gets very hot and invariably was extremely effective with the combnation of soppy wet fabrics still containing wash water chemical make up in the fabris. I was disheartened when I learned from HEnrik here taht both companies had done away with their steam generators in the washers probably due to cost.
As for the specification of 104 degree warm water on Normal, in their current design, that is only a capability with the heaviest soil level. Otherwise all other soil levels yield figures I have shown previously. Yes, LG did in the early 2010 decade provide those temperatures that were cited in their online literature. But it's way different now, maybe only here in the U.S. There was a member who found a discarded model back form that generation (like WM0624) or something like that. I looked up the manual onlne. Back then towels cycle was lumped into the category of being able to add steam or extra hot. Possibly even perm press. But the reality was, it was from back when my 2011 Duet was new on the market and the cycles on the LG offering steam or extra hot were very similar to my Duet, which as far as I was concerned was the standard of arrangement of features and heat were similar.
I will put temps in C for right now as displayed. I did two loads 2 days. Both on Normal one with hot and one with warm wash. Warm is obtained by alternating between hot and cold fill, not a mixing of the two. Unless extra hot is selected, hot also ends up with some alternating hot and cold. Both loads with cold outside, cabinet temp was 20C & 21C. The hot load filled with hot water and ended up at 38C and quickly went down to 35C. By the end of the 15 minute wash the temp had declined to 32C. Warm wash load after fill wat at 37C. Then began declining and by the end of the main wash as 31C.
Cycle where the heater will stay on (PP, Whites, Bedding, Towels) hot fill will otp out at 45C. With my water heater set at 120F, loads have been known to finish filling at 45C and begin to drop slowly since the target temp has been satisfied and won't come back on. Warm loads will fill between 33C & 35C and gradually decline from there.
