 I expect that household/consumer frontloaders with heaters typically don't actively maintain a target temperature for x period of time. They heat to a temp then are done with heating for the remaining duration of the wash period. I'm sure someone will advise if there are models that reheat to maintain a temp. | ||

I have LG WM4200H since Fall 2021. On my machine, if I select simultaneously the delay wash and temp buttons, I can display the temperature in the sump in C. This allows me to monitor temperature. the Allergiene cycle yields a higher temperature than my Sanitary cycle. Allergiene combines water heating as well as steam. Resulting temperature ranges from 69C to 72C. Allergiene removes any ability to select a soil level. Sanitary, at lowet to heaviest soil level yields temperatures ranging from 58C to 68. On Sanitary, once 68C is reached, the heater does not come back on to maintain temperature.
Extra Hot is an available selection for Normal and Heavy Duty. Select heaviest soil level and extra hot could yield temps of 68C. Allergiene offers temperatures as high as 72C. Again, other than Allergiene, all other cyccles that use Extra Hot tops out at 68C. | ||

The temperature does decline fairly quickly. There is no way to maintain the temperature such that it's a consistent 158F for 10 to 15 minutes. Maybe 4 or 5 minutes at best. You would need a Miele or Asko washer to maintain a consistent temperature for the sanitization parameters you need to adhere to. The Allergiene cycle MAY maintain a temperature of 158 for 10 to 15 minutes once the 158F is reached because the Allergene continues to heatabpve 158 before the heater turns off. . You obviously have parameters which must be met. Me, I'm just happy to have the water reach 158 or 160 and be that for 4 to 5 minutes max at best once the thermostat turs off the heater.
Regular hot for Whites, Bedding, Perm Press, Towels, the heater will only come on if it needs to heat water and that set temp is 112F. Warm is 90F. On Normal & Heavy Duty, the heater will only come on if Extra Hot is selected. All done by design to minimize heater use. That explains why LG's energy guide for these washers is 105 KWH/year vs. Whrilpool & Maytag comparable figure of 140 kwh/year. This post was last edited 02/18/2025 at 01:01 | ||

Sanitizing very dirty laundry
All it takes is a quarter cup of bleach in the bleach dispenser to sanitize clothing with far less energy and time wasted.
It also makes the washer last much longer. You’ll never get a gunky buildup on the spider which can destroy it and lead to major failure of the machine. Just be sure to use real bleach not the diluted stuff. John L | ||

Isn`t electrolysis the process to manufacture the bleach an energy consuming process too?
I wonder how much less energy is really used when using bleach compared to thermal sanitation in a modern efficient front loader. If you factor in the additional wear on fabrics and the environmental impact of the chemical I suppose it doesn`t look so good for the bleach. Never checked the spider but judging from the pump trap my washer must be clean as a whistle. No bleach ever, mostly liquid detergents in abundance, FS sparingly and regular 95° C washes seem to do the trick just as well. | ||

Oxi Clean by definition is oxygen bleach which is considered safe for "fast" colors .... but also akin to peroxide which is often used to bleach hair ... so yes, oxi/oxygen bleach can fade delicate/non-fast colors. Regards to sanitizing ... depends on what degree of sanitization is desired and what pathogens are involved. Typical liquid (and bar?) hand soap, for example, kills COVID-19 by disrupting the lipid layer that encases it. Other gnasties are more sturdy, calling for stronger methods. | ||

Batman, I live in Germany and use a Miele. The maximum temperature on the dial is 95°C (203°F) and the those cycles are still called "Kochwäsche" (boil wash) here but in fact no European washer for household use can go over 89°C (192°F) by design anymore, because the excessive steam would deform the plastic of the detergent drawer and fog up the area too much.
Unfortunately the Mieles on the US-Canadian market don`t even go higher than I think 75°C (167°F) because of limitations that come with the anemic 120V system. I was only making a point that chlorine bleach is not always the best choice, no intention to suggest a Miele. I think an LG with a heater should be fine in your area, they`re considered good value for the money here in the group. | ||

Hair color developer (hydrogen peroxide) are mixed with an alkaline substances (ammonia or something else) usually contained in hair color or bleach. Presence of alkalinity accelerates and intensifies action of hydrogen peroxide. Professional laundries, dry cleaners and others will add bit of ammonia to hydrogen peroxide when treating marks or spots to enhance and speed up action time. At temps < 140 or even 160 degrees F bleaching activity of all hydrogen peroxide based substances (including sodium perborate and percarbonate) is slowed. This is reason for all that "boil washing" across Europe. When using things like Persil (soap) or even early oxygen bleach containing detergents higher temps were needed to get things going. OTOH use of warm or cooler water temps slows bleaching action hence all those "all fabric" bleaches that were also safe for colours. No one was or should be washing colours (unless totally fast to laundering) in anything but warm or cool water. So there you are then... Problems began with introduction of bleaching activators. Those substances gave boil wash results at between 120 to 140 F or even 100 F. So now people could turn down the dial, save energy and still obtain same bleaching results. Problem is for colours those activated oxygen bleaching systems can take a toll even when only warm or cool water is used. This is why "colour" detergents came about in Europe that omit oxygen bleaching systems totally. | ||

In both North America and Europe (and one presumes elsewhere) there are standards or recommendations laid down for sanitation of healthcare linens.
There also exists various accreditations for laundries that process healthcare linen. Finally you also have agencies that certify disinfectants and other aspects of infection control such as EPA (USA) and Koch Institute (Germany) pmc.ncbi.nlm.nih.gov/articles/PM... www.cdc.gov/infection-con.... hospitalhealthcare.com/news/the-... journals.asm.org/doi/10.1128/aem... www.waeschereien.de/en/quality-m... What has evolved is a series of guidelines and (recommended) procedures involving healthcare laundry designed to produce sanitary results. | ||

State of Illinois says:
Linens shall be disinfected by using one of the following procedures: 1) Thermal Disinfection: Linen must be exposed to water with a minimum of hot water at least 160 degrees Farenheit for a cumulative time of at least 25 minutes. casetext.com/regulation/illinois.... | ||

What I was trying to express with "that allergenically important" is that while they aren't completely hypoallergenic, they are usually considered the much lower "threat" in that context. | ||
