Yeah, this is one of my biggest pet peeves with the LG. I do what Trok_99 does: I choose the Sanitary Cycle first and then switch to whatever cycle I want but the LG always fills with cold water for the first 5 seconds. I received after much haggling and threatening, a tech sheet from them indicating what all the temperature presets are. If you select HOT the machine will fill with hot water until it reaches 50C then mix in cold water until it reaches 40C, then it will switch back to HOT. By then, everything has cooled down. I've tried filling the machine throught the dispenser, which feels truly ridiculous and I've accidently triggered the "oversudsing protocol" a couple of times. The machine is very sensitive to tampering. I considered connecting the HOT and COLD inlets to a faucet that I could selectively make only hot, but I was afraid it would totally freak-out the computer and I'd have to pay for 13 years of Freudian Analysis for my washing machine.
The presets are:
HOT: 50 40
WARM:35 30
COLD:25 20
I much prefer the system on the MIELE and the Asko where you actually choose a temperature point for the water (usually from 60F to 200F).
By the way, for those of you who own LG's: you can test your interior water temperature by pressing and holding down the "WATER TEMP" selector button on the panel. It will display in "C" the actual water temperature inside the machine. Yeah, big whoop.
