Heather's Heavenly Vapes - THE BIG THREAD (Part 6)

yupperz... the PC stuff will be the demise of this country... eventually when "we" are all dead and gone and the country is full of snowflakes... some other country will come over here armed with insults instead of guns and take over by melting all the snowflakes by hurting their feelings.

I think I have a temp sensor going on my wash machine. When you put the temp setting on warm it will fill with cool water then the hot water will switch on for a bit then back to cold only then hot switches on. Back and forth. Lately it is switching every second. Used to switch every 5 - 10 seconds. Put in a new switch and that wasn't the problem. Tells me there is some kind of sensor that has gone super sensitive on me.

Maybe the solenoid on the hot water inlet is bad, intermittent?

 

[Bunnykiller]

sounds like trouble iz a brewin... why did they even design it that way?? on my washer, warm is both valves open at the same time... ( plus I never use the warm setting anyway) I prefer the control panel to be all mechanical, no puters involved. I had a gas stove/oven once that was computer controlled (yup... a touch panel gas unit) replaced the controller panel 2Xs, when it crapped out the 3rd time I bought a slide in old style gas stove/oven with knobs, no issues at all now.

Possible. It is steadily bad. Toggles back and forth quickly. Almost like the temp range of whatever is sensing the incoming water has narrowed dramatically. Cold water always stays on. But the hot water will kick on and off as needed (depending on the temp setting).

if that was the case, then the cold water would run consistantly during the fill cycle....

 

[Bunnykiller]

ahhh now we are getting somewhere
Im wondering where that sensor would be at??

Whirlpool is just being cute. They want their temps to be precise. If both valves are open at the same time then the final temp is determined on how hot your water heater is and water pressure, etc.... With a sensor, it can be regulated. Kind of like vaping.

Has to be near where it comes out.

lol... see, TC isnt all that great...

When it works it is.

 

[Bunnykiller]

I cant imagine that someone would go thru the trouble to design a washer that needs TC that accurate...
things it would have to consider is
pressure, flow rate, temp, variable flow control valves, and a program to determine all the data input.

its not like they are trying to keep a rocket motor burning

Thing is, I haven't found anything about temp sensor problems on this Whirlpool. Everything I have found is about the temp control switch. That isn't the problem. All I can figure is there is some kinda sensor in there somewhere.

 

[Bunnykiller]

hysteresis... thats the word
your sensor has a bad hysteresis issue

 

[DavidOck]

Possible. It is steadily bad. Toggles back and forth quickly. Almost like the temp range of whatever is sensing the incoming water has narrowed dramatically. Cold water always stays on. But the hot water will kick on and off as needed (depending on the temp setting).

If you can get to the solenoid and safely jumper the correct voltage to it (likely 120 VAC, but check! May be low voltage, but I suspect the controller switches 120 to the solenoids), would be an easy test.

Again a guess, but the temp sensor would logically be near the point where the hot and cold are mixed before entering the drum, and may not even be in the water, but outside.

Totally agree. But we come from the practical world. Temp control is for the marketers to make it look like their wash machine is elite. They call it "AutoTempControl". Just might get a few buyers jacked up, huh?

As in zero degrees!

That's what I would figger. It has to be mixed by the time the sensor reads it.

 

[DavidOck]

Maybe try a search with something like this:

whirlpool washer temp sensor location

and plug in your model number?

Might at least give you a picture of what to look for.

 

[Bunnykiller]

ehhhhh... just turn off the hot water valve
