WET3300SQ1 Water temp issues
« on: June 16, 2010, 01:24:19 PM »
On occasion, wife reports that water is hot when cold selected, vice versa.   I looked and she seemed to be right, but today I was going to tear into it, and checked the water and seems like cold is cold, hot is hot.  

I see a part called the ATC temperature on the wiring diagram, but can't find that part on the maching parts list.  Where is it, and can it cause weird water temp problems??

Thank you!

I took off the top, and there is a thermistor apparently, in the rubber fill hose, just where it comes off the valve module.   Here is a link to the wiring diagram which is inside the unit.   It is called the ATC sensor.    Can that, or the AT switch, be intermittenly wacko???

Have you seen this excellent water valve replacement video from Red? ?


Note. You gonna need to remove the splash plate between the dryer and washer on dat laundry center to access them spring clips and then you can get that case off just like you see in the video. Depending on the model is a little diff from year to year. Yours might be a skinny mini and in that case the front panel comes off. Here is a manual which features many different laundry centers including yours: THIN TWIN SKINNY MINI SERVICE MANUAL

I appreciate the work, and thanks for the parts list.   I seem to have an oddball.   Here is the water valve, showing something, I assume the sensor, in the outlet hose:

It I really confused because everything seems to say that if you select just plain COLD on the switch, it should be all cold.  The ATC comes in when you want to select hot/cold, warm cold, coo/cold combos.    Again, I triple checked and when I put it on COLD the hot water comes the lower of the two connections on the back, to the valve which has the RED connector.

Do you know if the thermistor should be hi resistance when cold, decreasing as it gets hot...or vice versa?   I will pull the top againg tomorrow and check it.   Depending on what it does, maybe if I just disconnect the thermistor, I can get some cold?

Thanks very much!

I did find a chart in the Accuwash job aid which indicates that the thermistor should be about 130 Kῼ @ 40F, and 10 Kῼ @ 150F.     I will check that tomorrow, and if it is OK, I guess that points to the ATC switch.     I will let you know.
