What is true of this model and changes how you fix it
- Hardware — GE Appliances product pageFront-control, stainless steel interior, Sanitize cycle (NSF certified), Piranha hard food disposer with removable filter, 16 place settings.
- Type & drying — front-control, Dry BoostA front-control GE dishwasher with a visible panel and Dry Boost fan-plus-heat drying (good on plastics when enabled). Rinse aid helps.
- Wash & tubStainless tub with adjustable racks. A manual filter must be cleaned periodically.
- The Piranha disposerA small disposer under the filter chops hard food so it can pass to the drain. It is there to protect the pump, but the removable filter above it still needs cleaning, and a clogged filter is the commonest cause of weak cleaning.
- Dry BoostDry Boost combines a fan with heat, which dries well, including plastics, when the option is switched on. Rinse aid helps, and the door opening at the end of a cycle is a designed behavior.
- Racks and armsA tall item on the bottom rack can block the upper spray arm or the water feed that serves it, which is why the top rack is the usual place for poor cleaning.
- Stainless interiorThe stainless tub retains heat, so drying and sanitizing work well, but hard-water scale shows as a white film that a periodic cleaner removes.
- Finding the model numberThe label is on the inside edge of the door; GE lists the full model as GDF650SYVFS.
- A hard-water noteThe stainless interior shows hard-water scale as a white film. A monthly dishwasher cleaner or a rinse with white vinegar, as the manual allows, keeps the tub and the spray arms clear and prevents the film from spreading to the glasses.
- Sanitize cycleThe NSF-certified Sanitize cycle raises the final rinse temperature and runs longer. It is useful for baby items and cutting boards, but it is not needed for everyday loads, and a long cycle that has Sanitize selected is working normally.

Exact questions
Questions that only have an answer for the GE GDF650 dishwasher
My GE GDF650 isn't cleaning the top rack.+
Usually the upper spray arm. Check it spins freely and its holes are clear, and make sure tall items on the bottom rack are not blocking it or the water feed to it. Clean the filter, scrape (do not pre-rinse) dishes, use fresh detergent, and run the sink hot before starting. Overloading the top rack so water cannot reach every surface is a common cause too.
Why is the top rack not cleaning?+

Do I need to pre-rinse?+
Scrape but do not pre-rinse.
What is the Piranha?+
A hard food disposer under the filter.
