GE GDT645SYNOFS Dishwasher Review: Pre-Owned 24-Inch Model Worth Buying?

A used GE GDT645SYNOFS dishwasher for USD 128.50, with a history that raises as many questions as it answers.

Last updated Aug 11, 2026

If you're shopping for a dishwasher, the hardest part isn't finding a model with enough racks. It's deciding whether a used unit with an unknown past can deliver clean, worry-free cycles. The GE GDT645SYNOFS, a pre-owned 24-inch built-in dishwasher listed at USD 128.50, puts that trade-off front and center: solid features and a low entry point, but a water-puddle story that asks for a little faith.

Quick verdict

The GE GDT645SYNOFS is a pre-owned dishwasher in a slate stainless finish. The seller says it functions as it should, but the unit was replaced after water puddling appeared in front of it, before anyone found the cause. That makes this a 'buy with your eyes open' situation rather than a grab-and-go deal.

Who it suits

This one suits a buyer who's comfortable with pre-owned appliances, can handle installation or arrange for a technician, and doesn't mind spending time checking connections. It also fits a kitchen that needs a 24-inch built-in in a neutral slate finish. Shoppers who want brand-new condition with no history will probably pass.

What stands out from the listed details

From the listed details, the stainless steel tub is a notable plus, and the door-top control panel keeps the front clean while the hard food disposer, removable filter, and removable upper rack make routine loading and cleaning simpler. The unit is built-in/integrated and 24 inches wide.

Meaningful trade-offs

The central uncertainty is the water puddling. The seller explains that their folks reported water in front of the dishwasher, then bought a new one before the seller could look at it. The seller wonders if a loose intake or drain line was to blame but clearly states they have no clue. Because the source wasn't diagnosed, there's no way to know if the unit would leak again after installation. That unresolved history is the main reason this isn't a universal recommendation.

This is the exact model and unit under review. It's a used 24-inch built-in with a slate stainless steel exterior and a stainless steel tub. The feature set includes a door-top control, leveling legs, a removable upper rack, and a removable filter, which are practical touches for everyday use. The seller notes that a first buyer couldn't complete the purchase, so the unit is offered once more. The clear limitation is the unknown cause of the earlier water puddle, which the seller didn't investigate.

Bottom line

At USD 128.50, the GE GDT645SYNOFS offers a well-equipped used dishwasher with a stainless steel tub and a practical set of controls. The deciding factor is your tolerance for the unresolved leak history. If you're prepared to inspect and possibly repair a connection, this could be a satisfying project. If not, you might prefer to wait for a unit with a cleaner track record. Weigh the price and the features against the risk, and you'll know whether this listing belongs in your kitchen.
