Kevin H La Porte , TX October 16, 2020 Appliance: LG Washer WM3470HVA Lg Washer Wm3470hva / : Pump not working. How to replace Washer Tub To Pump Hose. The drain pump was bad. With the help of Appliance Parts Pros, I was able to order the correct part and a couple of other things while I had the washer apart. These were the drain hose from the tub to pump and the mounting bushings that have started to degrade. The video on the site helped. Very happy the washer is working normally.
