Water Valve
So the water valves can determine how the machine handles warm rinses?

Does part 285805 differ from the original water inlet valve this machine shipped with?
The flow rate on that video changes several times during the wash fill when ATC switches between mixed hot+cold (stronger flow) and reduced flow of either only hot or only cold. There's no way to know for sure which way it's shifting ... hot to increase the temperature or cold to reduce it. The ATC sensor does not measure the water temperature in the tub. The sensor is in a module located in the hose between the valve assembly and the spray flume. The flow gets too high above or too low below the target temperature for x period of time, it changes between mixed hot+cold, hot-only, or cold-only according to what it needs to cool down or warm up the sensor for x period of time so as to attain an average reading around the target. I don't see the flow rate change at any time during the rinse fill, which appears to the stronger hot+cold flow rate. I am assuming that hot+cold at that person's house satisfies the ATC warm *rinse* but is a bit too low for warm *wash* and the wash fill is switching occasionally to full hot.
There may be others but the only ATC system I've seen that directly controls the valves and mixes the incoming spray to the specific target temperature are some Fisher & Paykel models that can directly control the flow of the valves, presumably by moderating the (DC) power to the solenoids. I have one that, for example, targets 46°C (116°F) for warm. I have a tankless water heater. The water spraying from the fill flume stays at the target temperature if I set it to at least 116°F or raise it progressively to 140°F.

It does in that it is a replacement valve for many direct drive machines and there are 2 ways to mount the replacement with or without a bracket that comes with the part depending on the machine it is being installed on.

So a new water inlet valve would take away from what the machine originally did? If I am understanding that correctly. Part 285805 would not do a full 50/50 warm rinse, or even 60/40?

It’s different in the way it installs not in the way it functions.

How can it be installed differently?
50/50 vs. 60/40 valve mixing proportions doesn't have an appreciable effect on ATC temperatures. The valve operates only three ways ... both solenoids on for mixed-warm at the valve proportions, only the hot solenoid for tap-hot flow, or only the cold solenoid for tap-cold flow. The ATC circuit board that comes into play on ATC settings switches between those three operations to attain the target average temperature. ATC warm is mixed hot+cold with possible occasional tap-hot or tap-cold if necessary to attain the average. ATC cold is tap-cold with occasional hot+cold if necessary.
50/50 vs. 60/40 does have an effect on non-ATC warm when the electronic board is not monitoring and controlling the temperature.
285805 was mentioned recently as a 50/50 proportion valve for anyone who wants to replace a 60/40 valve. It includes an optional mounting bracket/plate to adapt it as a current substitute for machines that had an original valve (now discontinued) mounted to the back panel differently than the 285805 otherwise fits.

Here is my current machine. It does not do a 50/50 warm warm or 60/40.
50/50 and 60/40 refers the percentage proportion of cold and hot when both solenoids are open for warm. 60/40 valves have a smaller (restricted) channel for hot water such that cold water is 60 percent of the flow and hot is 40 percent when both solenoids are open for warm. A 50/50 valve is equal proportion cold and hot.
What proportion is the valve on your machine if not 50/50 or 60/40?
Hot and cold water valve percentages
Whirlpool built washing machines in the 60s had a 6040 valve, 60% hot 40% cold water was provided when you had the machine set on warm.
That was changed when they went to the yellow valve on the belt drive machines it became a 50-50 valve.
Later they went to 40% hot 60% cold to save hot water, recent Speed Queen top loading machines for example Are 30% hot and 70% called when set on warm.
In my experience it certainly doesn’t matter what temperature you rinse in, in fact I love my new laundry room set up with seven washing machines hooked up so far in this time let of year the water is in the 40s coming out of the cold tap, it does cost a lot of money to heat it because I only wash in hot water generally but I love rinsing in cold water. Clothing smells so fresh and nice when it’s taken out all nice and chilly if it weren’t so expensive I would like to have ice cold water to rinse in in the summer as well think I’ll refreshing that would be.
Coldwater actually rinses out detergent and bleach better try it yourself. In addition clothing never sours if it’s left in the machine any remaining bacteria is held at bay until the clothing is completely dried. Much lower germ counts with the cold rinsing.
I’ve never seen it single detergent manufacture or washer maker recommend warm water rinsing , there are certain concessions we must do to save the world climate change is a very real thing in this is a very simple thing to do that actually works better.

I was thinking more along the lines of rinse only, not the main warm wash, which would be 60/40, 50/50, like you said.
The machine I posted in Reply #27... does that use 50/50 or 60/40?
