How to Troubleshoot & Replace Whirlpool AP6021886 / WPW10467289 Washer Water Temperature Sensor

We had to replace the water temperature sensor. And our washer is a whirlpool duet sport and the video they have on her said to remove the front but not on this model you do have to remove the back to get to the sensor. Other than that it was very simple task and now my washer works great! 

It was unplugged might want to check before ordering the part 

Replaced the water temperature sensor and cleared out the error codes. Washer has been working fine. Turned out to be a very easy fix. 

Washer started throwing F3E2 code (again). At first, could clear the code, but eventually got to the point where it would not clear. The sensor replacement is simple - unplug power, take off back panel, unplug sensor, pull sensor out of rubber grommet, apply a little water to the sensor surface to lubricate, insert new sensor and put it all back together. The only negative... this is the second sensor I've had to replace in the last 6 months. The first replacement (from AppliancePartsPros) appears to have started failing intermittently. I checked the wiring harness (which I also replaced a few months ago for a broken motor connector) for continuity, checked the sensor resistance at the sensor and at the CCU end of the wiring harness... everything looked OK. But the new sensor appears to have fixed the problem, and APP is refunding the first sensor purchase, so all is well. 

Replacing water temperature sensor was very easy. The video showing how to do it was very helpful, except for the fact that in some models of this washer, including mine, the temperature sensor is in the rear of the washer, not the front as described in the video. Fortunately removing the front cover wasn't wasted effort since it's a good idea to clean the water trap from time to time. I'm always surprised at what I find in the trap. 

Replaced the temperature sensor but that did not fix the problem, connections are good and tight, the rep at Appliance PartsPros was great, very helpful and courteous 

Purchased new sensor and seal. Watched a video on the repair that said the sensor was behind a panel on the front of the machine. Actually it was behind the back panel. After finding the sensor it was a 5 minute repair. Most of the time was moving the machine to get access to the back. 

Removed the back panel, unplugged a small wire from the sensor, pulled the sensor straight out, pushed the new sensor in, plugged small wire back in, replace the back panel. The sensor is in an open and very easily accessible spot. It took longer to remove and replace the screws holding the panel on than it did to replace the actual part (and I used a cordless drill). Easy peasy. 

Narrowed the problem down to a possible sensor/thermocoupler in the washer drum. Ordered the replacement sensor and removed the rear sheet metal panel, easily removed the old sensor and installed the new unit, effortless! The washer now runs thru all cycles without stopping and beeping! 

Well after looking online everywhere and trying the infamous "cleaning the drain basket" which by the way did NOT fix my problem because there was nothing restricting it, I ordered the water level pressure switch. It was amazingly easy to fix. I just unscrewed 3 screws from the back top and popped off the top cover, and there it was. On the top right corner of the washer next to the drain hose was the part. Took me about 5 minutes and I didn't even have to do any resets or anything. I just started working on its own.
