The Tank › Water Temp Too Hot. Whirlpool says bad lower element › Reply To: Water Temp Too Hot. Whirlpool says bad lower element
It appears the new elements have solved the problem. Everything seems to be working normally now. The temp is holding steady at 120-ish when measured with infrared thermometer at closest faucet. No errors on the front panel display, and elements status is changing on display when energized. Unit has now been powered on for about 4 hours or so.
Now, whether there was a bad element (or two) is still in question. I suspect the thermostat might have gotten confused (power surge/blip, perhaps?) and just needed to reset. After everything cooled off it seemed to be working even before replacing the elements. I setup one of my Arlo cameras in the basement/crawlspace so I can peek in on it without trudging down there to check. Hope it behaves now.
I’ll test the old elements now that they are no longer contacting water and measure the resistance of each and compare.
