GE GDF630PSMSS Repair Guide
GE’s volume front-control dishwasher with the Piranha hard-food grinder — one of the few remaining machines with a grinder instead of a fine filter, which changes its maintenance story: less filter cleaning, more attention to what goes down the sump.

Tech notes
Grinder machines tolerate scraps better but hate pits, glass, and bones — the "rocks in a blender" sound is your cue to stop the cycle and fish the sump before the impeller chews.
