Mary K Beaverton , OR November 18, 2015 Appliance: General Electric Dishwasher GSD5500G00BB Ge Dishwasher Gsd5500g00bb: Bottom rack was rusting. How to replace Lower Rack Assembly. I bought the GE replacement rack for my model, the quiet triton dishwasher. I wasn't sure about the size and fit because the description says 23" and the old rack is 22" deep, but it fits perfectly. The layout and silverware basket are different than the original, but I actually prefer the new style and the rack itself is much lighter (less metal to rust-out?). I bought the rack from appliance pros because of their guarantee, in case it didn't fit. Very happy with my purchase and delivery was, literally, less than 2 days.
