How to open a GE Hotpoint HTW200 washer?
I'm not certain what part you're referring to replacing, but PartSelect has diagrams of all the component parts (and sells some of them). If you need to get completely into the cabinet, it doesn't look like there's a panel to remove &amp; may need to be accessed from above. It appears the top panel is held in place by spring clips (328) and a couple screws (570)? But it looks like you may have to take off the controls to get to those screws. 

I'm not an appliance repair technician, so take my ideas as you would any other from a stranger on the internet.
