What’s the problem are you having? Is it the control panel? Do this:Control Panel Removal

1. Remove both Quadrex screws (a #2 Phillips

screwdriver can be used to remove Quadrex

screws).

2. Press in on the retainers to release the control

housing assembly.

There is a second retainer on this this thing that is apparently hiding the rear screw…and it is inviting me to damage the whole unit.

That looks like if you use a putty knife it would come right out.Here is what I think you’re talking about about in the back? https://www.partselect.com/PS283598-GE-WR01X10149-CLIP-CANOE.htm?SourceCode=1&SearchTerm=CTZ16EACDRWW&ModelNum=CTZ16EACDRWW
