The complaint on this machine is all cycles & all temperature the water fills with hot water.   I don't think it is the cold water solenoid, rather the electronic temperature switch.  Is there a way to test this switch?  Also I read somewhere, I don't remember where, how to test the load sensor switch.   I replaced those for spin, dead, and agitate issues, really by trial & error.  If someone can lead the way...

Not sure about testing the ATC but here's something:

 

Whirlpool Service Pointer L8178746 - Hot water may enter when cold water is selected

 

Customer concern:  Hot water may enter when a cold wash or rinse cycle is selected.  The technician has verified that the water inlet hoses are installed correctly.

 

Cause:  Units with an Automatic Temperature Control Switch have a feature that will electronically regulate the hot and cold water supply if it senses that the hoses are reversed.  The software in the switch may be out of calibration and could trigger the automatic hose reversal feature at too low of a temperature.

 

Correction:  Order and replace the ATC switch.  All of the parts in Whirlpool's inventory have been reprogrammed to correct the temperature calibration.

Bruther Duff has nailed it!

 

They had another pointer out that said "siphoning" could also cause the ATC to go out prematurely.

Domo, Brother PDuff!  Link to the hot water cold water bulletin:  http://appliantology...rvice-bulletin/

 

ATC switch needed to correct the problem:  http://www.repaircli...0179666/1471455

Brother Thirsty, if you have a bulletin number on this one, I'll upload it, too.

Ya know, now I'm wondering if it was just mentioned in update training a few years a go.

  I had first thought about that problem but didn't think it applied to this washer. This Kenmore is an 09 model. The switch problems were all in 06 and 07 models with the bulletin coming out in 08. Also, in rinse mode, cold water valve is selected directly, not through ATC switch.

Thirsty's right.  I thought that a pointer or update on drain hose siphoning was issued years ago but I couldn't find it.  Found it in the new Search Center.  Service Pointer W10611623 issued May 2013.  May 2013....really?

Eric, I was thinking that as well.  The IPL shows both the ATC and Auto Sense Switch used in this model.  I think I remember the same issue on a Maytag that had both switches around that time frame.  :kopkrab:

PDuff had this one nailed.   Initial visit I  traced red faucet handle water line to 'H' inlet on washer.  Blue faucet handle water line to 'C' inlet.   Water heater is right next to washer so it has instant hot water.    Initial visit wash cycle filled with cold water on cold switch like it is suppose to.   Then when I switched to warm the water valves cycled hot & cold.   When I went to hot switch I got very hot water.   Then it never would go back to cold when i switched to cold.    Several different times @ different cycles.  Customer had no problem with machine all the years they owned it till recently.

 

I ordered the ATC switch & installed.  Ran cycle & everything seemed find until I went to rinse cycle. It filled with hot water.  Had me stumped for a minute.  I reached behind the washer & felt the water lines.    The blue cold side was the hot water.   The ATC was compensating for the reversed (marked) water lines until it finally failed.

 

Moral Follow Samuria's rules of battle,  assume nothing...check everything.       I put the original ATC back in to see if it might be good...It was corrupted would not regulate correctly.

  Did they recently reverse the hoses? With hoses reversed, they would have always had hot water rinses as rinse cycle activates cold water valve directly, not through ATC switch.

I replaced the set of water lines because the blue handled hot line was swelled in several places so I do not think the hoses were changed recently.  I used red & blue colored water lines so as not to mistake them in the future.  I also labeled the faucets appropriately.  I added an extra charge for the additional service.
