 We refer to that around here at "dumbed-down" temperatures. Energy savings. The designated Normal cycle is typically the most-restricted being that it's used for EnergyStar ratings/qualification. Cycles other than Normal usually run higher temperatures. The specific behavior varies from one machine to another, you just have to try all the various cycles and settings on your specific model to find what does what and what works best for your needs. | ||

 What I’ve found with my 2004 LG is, if I want to wash in “warm” I set the controls for “hot” on the normal cycle. I have one of those hand held temperature “guns” and as I point it through the glass during the wash, it usually shows around 95-96 degrees. Glenn, that’s a very interesting point for the “normal” cycle that I didn’t think about! I’ll have to start a load on the cottons/towels cycle on hot and see what it does. I ran a load a while back, as I recall thought it odd it filled only with hot, but don’t remember now if that was the cotton/towels or normal cycle. Thanks! Kevin | ||

Modern washers filling with cold water at first. Even when hot is selected
Most machines do this as part of the safety door or lid locking system.
Ever notice that most washers when started lock the door, then the tub moves a little to wake cat or child that might be in machine and sprays a little cold water and then unlocks door so inhabitant can escape before cycle really starts.
This is the reason they start with cold water and not hot, otherwise it would be far better to flush dispensers etc with hot water.

My Duet behaves similarly: it will flush the detergent down with cold water and then cycle between hot and cold until it reaches a max of 104F in the tub and use the heater to heat to the target temp.
This makes sense - especially in Europe - so enzymes can do their best job without being cooked by an (immediate) hot fill. GE washers called this initial cold fill a feature to prevent protein stains from setting. | ||
