Just purchased my first Speed Queen. Like many others, I will be taking steps to raise the temperature of my "warm" wash. Eventually, I plan to add a tempering valve to help level the temperature of the incoming cold water. Until then, thought I'd get a lay of the land.
So far, I've taken advantage of the clothes pin suggestion & replaced the fabric softener dispenser with the appropriate agitator cap.
This weekend, I decided to remove the fill valve for a look-see. Considered opening up the hot side so that it matched the cold, which several members have suggested.
Unfortunately, I see no external evidence that hot side is materially different from the cold. Posted a photo with the screens removed.
If anyone had any comments or suggestions, I would be happy to listen. Thanks for your help!

They did away with the 30/70 mixing on the 2015 models, what you have is 50/50 mixing like it used to be and how it should be. Any further requirement in increasing warm wash temp should be done by turning down the cold water valve a little if possible, or turning up the hot water temperature (sometimes not practical if the cold is extremely cold and the hot is already around 140) or adding a tempering valve to bring the cold up to about 70°.
I was thinking about adding a thermostatic mixing valve myself so I could have warmer rinses as well as warmer warm washes (rather than switching to hot 3/4's into a warm fill), only problem is I can't get to just the lines running to the washer, the mixing valve would have to go on the line in the basement making both the upstairs bathrooms get the tempered cold water too, though that may actually not be a bad thing...
This information clears up a few remaining questions I had about some of the possible workarounds. Won't waste my time swapping electrical leads & hoses because it would be a wash. Pun intended.
Don't think I have the patience to mix hot & cold as the tub fills, so see a tempering valve in my future. Problem is finding one with a low set point that is reliable.
