excuse the perhaps obvious ? don't pay much attention to non-vintage machines...
so our 1 yr old BOL Hotpoint top loader has the usual 3 water temps, but on the Hot setting the water is merely warm, at best. Is regulating (lowering) water temps one of the "features" on new machines to make them more "efficient"? I like to wash whites in really hot water, Sears detergent, and a bit of bleach, and the temp at the faucet of the adjoining laundry sink comes out steaming hot... what gives?
 
well, in this case, YES, your machine has a dubbed down setting, that you can't actually change....

not one choice will work for all machines....but we have done a few, some work, some don't....

some have tried to turn off the cold side when it fills, but doesn't work on all machines, as some will detect that the cold side is not available, and shut the machine down.....

you can try unplugging or removing the thermistor to see if that allows an all hot fill...

some machines have it built into the timer, when hot is selected, it allows for one minute of hot water, and then switches to either warm or cold for the rest of the fill....

you have to try different options....and still may not be able to get the temp you want....

one advantage you do have is the sink, as you can always hook up a hose to it, and fill the machine manually for the wash...that may be your only option....
 
 

 

I have a 2005 LG washer and this thing really "dumbs down" the wash temps. If I want a "warm" wash, I have to select "hot", as "warm" is maybe luke warm at best. The thing I really don't like is, no matter what temp you select, it always flows cold water about 8 seconds when you start it. I've tried adding hot water with a hose through the dispenser, but at some point, if the water is "too hot", it will start adding cold water again.

 

My "hot wash work around" has been, turning the cold water valve down to a trickle and adding hot with a hose through the dispenser. I have the cold at a trickle so I know when the water level has been reached. If I add too much water, it will start draining after only a few minutes of wash time. Fortunately this isn't my only washer, so if I want a "real" hot wash, I'll use another machine rather than baby sitting this one.

just did the hose fill...

to do a load with the super hot water as it comes from our tap, set around 170-180, and what a difference! When that load was done checked the water temp when on just the "Warm" setting, 105-110 at best.. sheesh! So to get Warm we need to set on "Hot", and manual fill to get truly hot water...not sure SWMBO will willingly go thru that rigamarole, I need to fix the 1:18 and put it on line!!

can you post a pic and model number.....

just wondering if there is a way to 'override' this somehow......all we can do it try.....

what does it do when you select HOT?.....does it cycle back and forth, or hot only for a short time, and then warm/cool mix to complete the fill....or what happens if you turn the cold faucet off?.....

I don't expect a BOL machine to have intricate programming or wiring for getting past this, but then again, anything is possible...

probably the best thing you have going, which many overlook to start with, is having your water heater set to a high setting, like 160-180......I have mine set like that, always have, always will.....most machines with internal heaters can't compete with that....KUDOS to you for that one!

many people select hot, when their water heater is set to 120....their not starting with real hot water to start with....WTH?

I only have one machine that dubs down, and the loss is only 10 degrees....its a Cabrio, tried pulling the internal thermistor out of its socket, but that affected the warm setting......found it best for this machine to remove the restrictor on the hot valve side....

ironic, Auto Temp Control was only for raising cooler temps....making sure warm was warm, and cold was raised for proper detergent activation, hot was never controlled.....odd how we have gone in a opposite direction......I expect the next generation of machine to have an ice maker dropping cubes into the tub!
 
Why would you launder anything at 170-180 degrees

Sanitation, disinfection, stain removal, heavy soils/oils, these are just off the top of one's head.

For European washing machines they were designed with those countries methods of washing in mind; that of the old ways which is to use very hot to boiling water for at least whites and colourfast.

In the old days you did such things to get best cleaning with what was available (soap and basically soda), but then came oxygen bleach (sodium perborate) which really only gets going at temps >140F.

By the 1970's or 1980's bleach activators came along (they were introduced due to the energy crisis) enabling one to get boil wash results even at hot or warm water temperatures.

Americans OTOH never really went in for oxygen bleach, but instead use chlorine based agents. Chlorine bleaches work in hot, warm or cold water and are well suited to the short cycles other features of top loading automatic and semi-automatic washing machines. Indeed boiling went out for most American housewives when washing machines came in.

If have badly soiled/stained laundry it goes into either Miele or AEG; set the machine to 180F or 200F, add a bit of Persil "universal" (Henkel), and that is that.
 
model # HSWP1000MWW

3.6 cu. ft. cheapy BOL model, think we paid maybe 320-ish, delivered? We assume that we won't be in this house for more than 1-2 yrs and will leave it behind. Not a bad machine, actually, has a ribbed tub plus a 2 stage agitator: lower paddle, screw top, and it seems to move water around pretty well. Puts a fair amount of H2O in the tub and although far from state-of-the-art, except for the temps it does a reasonable job, no complaints all things considered.

I misspoke on temps, on the Hot setting it's more like only 110-115 degrees, on Warm it feels more or less like Cold to me, even after filling for some time, and the temps remain constant thru-out fill.

Rather than futz around with internals think I'll just teach swmbo to fill it with a hose using tap water that comes out steaming hot, it may be more like 190+ degrees. For whites I like the old fashioned way of really hot water, NaClO, and use big orange box Sears detergent we picked up on sale 2 yrs ago on the recce of some folks here. The load done yesterday came out great. Best of all it's finally hang-on-the-line time in upstate NY... gotta love the way everything smells soooo fresh!

Easy peasy

Getting hot water on this model is by far the easiest. No need to cut wires and re-splice others as with most other models. All you have to do is unhook one of the water valve terminals. This model has 3 water valves, and when set to hot a single cold valve simultaneously opens giving warm- when warm is selected two valves open to give cool. I am unsure which terminal to unhook (dont have the schematic in front of me)- I believe the one with the yellow-black wire- but you can confirmed via the tech sheet in the control panel.
 
Warning Notices On Hot Faucets?

Hey, Roger,
I hope you have warning notices on faucets that house guests might use informing them that the hot water coming from the tap can scald them within a second of contact.
170-180 is a WAY too hot water temperature for a home setting.
I'd hate to be in the shower when someone opens a cold tap somewhere in the house!
AAAAEEEEEEEE!!!
 
yeah, I got those temperature adjustment valves on the tub/showers....or rather, they refer to them as Anti Scald valves....

actually its a little disc under the handle, that you can adjust to 'set' the actual highest temp that would be allowed...all it does is control how far the knob can be turned towards the hot side...

to save even more water, at least in the kids bathroom, a flow restrictor is installed, 2 gallons per minute was still too much for my liking, so I used a dime, and drilled a tiny hole, to reduce usage to 1 gallon per minute....still plenty of pressure for the hand shower.....flushing a toilet has little effect on temps....
 
Like most new energy star machines, our new LG top-loader has the dumbed down hot water, even on the "Bright Whites" load. I love the way the machine works otherwise, and it can be set to use extra water, except that, of course, it is cold.
