NO, NO, NO....your getting the best possible mix.......opening up both the same, its as close as possible.......
the before of your machine was not allowing a full 50/50 mix......that what was confusing some people, yeah, if you selected HOT, you got tap HOT water, same for COLD, but if you asked for WARM, it was more like 70/30, or luke warm if even that.....some people weren't even checking as to the actual temp once the machine was filled......like Malcolms machine, once locked, he can't be sure he's getting a true warm wash, or even hot for that matter.....
something just to keep in mind.......WARM is determined for you now based on incomming water temps.....if the COLD is icy cold, and your water heater is set at 120, you may be only getting a luke warm wash, and this can also change by the Season, and the area you live......thats why mine is set at 160, I can always turn the faucet down, and adjust to my liking.....
check your wash temp, warm if I am correct should be around 90 to 100F....
