What is wrong with the washer, or how is it not functioning properly?
I've used Appliance Parts Pros to diagnose the problem, purchase the part and they have instructional videos showing how to replace most parts... I hope this helps!
I would use the site mentioned above and look up what’s wrong on YouTube. Just make sure to view a few videos to make sure there isn’t a step left out.
Can't answer unless someone knows what is it doing or not doing.
I also have good experience looking on YouTube then going to a "parts pro" site and ordering the part for less than $5. I got home from work and my 11 year old son had fixed it and was doing laundry! I felt very lucky.
It depends on what's wrong. You could try a simple fix as suggested above but be careful to not make things worse.
