Hi.
I was wondering if anyone knows how to get a 'TRUE' hot wash in a front load washer. I have a new Samsung front load washer and when I select the HOT for wash temp, the water is just very warm.

I already tweaked the machine to add more water to it, and it works great. How, I would like to know if there is a way to get a true hot wash and a true warm wash.

PS: Is you want to know how I got it to add more water, let me know.

Any help for getting the hot water from the water to the machine without mixing cold, would be appreciated.

Thanks

Ray
 
Do you purge the cool water standing in the hot water lines before you fill the machine? This is especially important if the water heater is not close to the washer. Have you measured the water entering the washer and compared it to what you get from a hot water tap? If the machine is adding cold to the hot fill, you will have to overcome that by either turning off the cold faucet during hot fill and see if the machine will still fill or by sticking a hose in and filling it manually with hot water. If what you are experiencing is temperature drop from heat loss to cold machine parts, you can fill it with hot water without any laundry in it, let it tumble a coule of minutes to heat up the machine then do a cancel and drain and start over with the load in the machine.

Hi Tom. My washer is about 6' away from water heater. When I select normal, temp HOT, the machines starts out with HOT water and then about half way through the fill it finishes with COLD. I was wondering when I select the STEAM option if that would heat the water in the machine also.

Your thoughts.

Thanks, Ray

Getting back to adding more water.... I was able to do this on this machine. It is a simple turn of a set screw. The water level for the normal cycle comes up to just over the tub and on to the boot, and over the boot for the rinse. You see a nice sloshing action. Now on Permanent Press and Delicate, the water comes up below the the door that juts into the machine. The rinse and spin even higher.
The delicate cycle come up about 1/4 or a little more to the middle of the window.

I now get a good wash and rinse action.
 
This is a classic case of the built-in "we know best" auto-temperature system that can't be changed as far as I know.  I get the same thing in my Affinity.  When we had a Duet at the other house, I tried to turn the cold supply down to a trickle and got an error code as a result.

 

As far as I know, there's no getting around it.  Sometimes what I do is let the water from the tap at the laundry sink get not quite hot before turning the machine on, which often tricks it into not adding cold water toward the end of the fill.  YMMV depending on load size.
 
you can also try removing the plug from, or the whole sensor unit, that monitors the temperature.....

this depends on where and how its connected/located......

on the Cabrio, the sensor itself pops out of a slot...the good side....all HOT fill...the down side, no warm wash.....with it connected, theres only a 10 degree drop from the water heater temp....my water heater is set at 150....I get a 140 in the machine....

on the Frigidaire FL.....all I had to do was unplug the sensor....and there actually is a blank slot to slide it into....it disables the Auto-temp control...

odd...used to be, Auto-temp control was adding Hot/Warm to a Cold wash so detergent would disolve and activate.....now were going in he opposite direction.....

I don't get these drops in Temps or insisting on a COLD water wash......I could see the savings for a TL machine....but the whole idea of getting a FL was that I could wash in HOT or true WARM, and save money because of the small amount of water needed versus a TL......not to mention the higher spin speeds.....for less drying time....may be its just me!....

all I can say Ray, is try a few things and see what happens when it fills.....another trial and error and see what you find....
 
I wonder what would happen if when it tried to add cold, you kept the cold faucet turned off and filled it with hot water from a hose through the dispenser. I support that kind of forced feeding. It would seem that once the water level switch was satisfied, it would get on with washing. It's a shame we can remember when automatic washers could be set for what WE wanted them to do.
 
these new machines have idiotic intelligence installed.....it will give an error code, more along the lines of self diagnostic, and alert if either HOT or COLD is turned off......

in vintage machines, for many people who washed only in COLD water per say, would only hook up to one tap, and cap off the HOT water side......can't be dont with many of today machines.....we have that issue with testing machines in our garages, even with a "Y" connector, for one its looking for water pressure, and two it will open only the HOT valve expecting the temp to change as normal hot water would arrive to the machine....

Like Ralph, I have tried turing the COLD off, or down to a trickle.....damn thing senses that as being a problem, you will get an error code, and/or machine shut down until problem is corrected.....

were looking to override this, and have the machine do this automatically......not always the case......the only choice so far is to babysit the machine, and do it the manual way.....
What you can do, is let the machine start to fill, hit 'pause', and then fill thru the dispenser with HOT water only to a level you require, and then hit 'start' to continue with the load.....thats about the best we have so far....

some things we can alter......and some things are built in that won't allow us to do so....

one thing I did to the Cabrio yesterday, took the restrictors out of the valves, now the fill is full flow and fast, not this eye dropper trickle which took forever for it to fill....WTH did those restrictors serve except to make a 1 hour wash cycle take even longer...
 
Anything electronic that can be done

can be undone...

If someone was a bit resourceful the temperature sensor could be over ridden or at least tricked to read in error.

Most likely (I'm guessing here I don't know the machine in question) there is a sensor which is simply a temperature dependent resistor which provides feedback into the computer. Perhaps by adding resistance in series or parallel would allow one to trick the computer into providing different temperature water. It might even be possible to have an external control that allows one to dial in the temp they want.

The only fly-in-the-ointment I see is the possibility that the control looks at the sensor for changes in response to valve actuation. If this is the case it might thwart attempts to game the system.
 
Reverse the Hoses?

I know it sounds stupid, but seeing as you've tried reducing cold flow to no avail, perhaps reversing the hoses would work? To be quite honest, it is none of Samsung's business how hot your cold tap is. What if you live in the Sahara desert? 

 

You could also try using a tempering UP valve to increase the temperature of your cold water for the washer - instead of it being in the 60s or 70s, you could make it into the 90s or maybe just tipping 100. Again if the machine can't get cold enough water, will it "chuck a spazz?" This would be worth considering if hose reversal works fine, because that proves it just cycles. 
 
we tried to reverse hose procedure.....but then we got all HOT rinses...

as much as you hate to, raising the water heater higher might help.....adding COLD water to 120 degree water will give you a luke warm wash versus adding COLD to 160 degree water.....you may not get total HOT water, but close to it...like I said, I am only getting a 10 degree drop......your mileage may vary

give it a try, it might work....
 
Thanks for all of your suggestions guys.

I really love the machine since I did the adjustment for more water.
When I get a chance I will take a video. The machine really cleans great and now ever better rinsing with the added water.

I was thinking.....what if I connected both the and cold with a splitter valve for the wash???? Meaning both hoses with a splitter hooked up to the hot water valve??

But then how would I get a cold rinse??? Is there a way to do this with another splitter???

For now I just select a hot wash when I want a warm wash.
I was wondering if I use STEAM option if I would get a hotter wash?

Comments please?

Thanks Ray

HI Laundress.

Yes I have that AEG from 1991 and it was only used for a year on a regular basis and once in awhile for delicates after that. Machine is in mint condition, however, the tub is so small.
