Cited as a midgrade Frigidaire built-in dishwasher, the Frigidaire GLD4355RF is a direct upgrade from the Frigidaire GLD2445RF. The GLD4355RF trades in its predecessor’s Active Vent Drying System for a Power Dry Drying System, and adds along a Pro-Style towel bar designed to complement the dishwasher’s elegant look, not to mention AquaSurge & Variable Washing Pressure. In addition, the GLD4355RF sports a premium stain-resistant GraniteGrey Interior, a Smart Soil Sensor that measures food soil in the water and then adjusts the wash cycle as needed, and a stainless steel food disposer. The GLD4355RF also boasts 12 easy clean electronic touchpads, a Half Load Wash option that offers economical/energy-saving operation for small loads, an NSF certified Sanitize Rinse option that sanitizes dishes and removes up to 99.99% of all bacteria, a variable (1 – 24 hour) delay start, and an UltraQuiet Plus Sound Insulation Package. The Frigidaire GLD4355RF retails for a slightly more expensive $549.00 (versus $449.00) in white and black and comes with a 1 year limited warranty.
