For the water not draining, we replaced the drain pump. For the TE error, we replaced the thermistor. Your website was easy to find the parts and step by step repair videos was a great reference. The parts were affordable and delivery was fast. It made our decision to fix it ourselves a no brainer instead of buying a new washer.
For those having the same problems, although the video shows that you have to remove the top and front panels to access the drain pump and thermistor, we discovered that it was easier to lay the washer on the side and go through the bottom of the washer. It cut down your time by 90%.
