Jonathan E Camden , ME June 24, 2016 Appliance: LG Washer WM2101HW Lg Washer Wm2101hw / Abweeus: Thermister error on lg washing machine (te). How to replace Heater Assembly. Changed the heating element. Apparently you can't buy just the Thermister which took me a while to figure out. There is a very helpful You Tube video on how to take the front off the washing machine so you don't have to crawl under it and risk getting squished.
