Product review (5 stars): Easier than I expected!
We have a 7 year old LG washer. It recently stopped washing and would show the blinking LE error. I tried to shut it down and restart. It would run a little in hand wash cycle, but invariably the LE error returned. Just running a spin cycle was impossible. I tried to schedule a repair, but (luckily) the repairman did not show as scheduled. I finally figured I'll give the rotation sensor a try. For this price, less than $15 including shipping, I did not think I could go wrong. The part arrived in 3 days and I followed the YouTube video for instructions. The hardest part was removing the 17mm center bolt. I used a 1/2 breaker bar with a 17 mm car lug nut socket. It took maybe 10 minutes at the most and could be done in five, very easy to replace this sensor and to my delight the washer is back to working order. Pretty cool fix!
