DIYbanter - Help with GE Potscrubber Dishwasher

I have a GE Potscrubber 2230 that's about 12 years old. It came with
the house I bought and every since we bought the house, it has a
problem where it will run normally for about 33 minutes of the 44
minutes it's set for and then quit with a C5 error code. At this
point, there's still water in the bottom of the machine but the soap
cup is opened, leading me to believe that the wash is complete and it's
just the rinse that never happens. The water won't pump out unless I
let the machine sit for about 20 to 30 minutes, at which time, I
unlatch and relatch the door and the pump kicks in to remove all the
water.

Anyway, someone I know who just redid his kitchen had the same
dishwasher and had a similar problem a few years ago. He had his fixed
by replacing the whole control console. He gave me the part to try in
mine.

Here's my question.

Before I fiddle with this thing, are there any tricks to removing the
console I should know about? It looks like the whole inside of the
door comes off, and I'd imagine that would provide access to the part
I'm replacing. Is this right or is there some other way to get to the
console?
