Source: lg.com (verified 2026-07-07) · corroborated by merlinstv.com. LG.com's official product page for LDTH7972S confirms the exact model and name ("24 Inch Smart Top Control Dishwasher with 1-Hour Wash & Dry, QuadWash Pro, TrueSteam, and Dynamic Heat Dry"), the height-adjustable 3rd rack, TrueSteam with NSF sanitization, ThinQ Wi-Fi, and a list price of $1,499.00 (PrintProof Stainless Steel; Black Stainless $1,549.00). Merlin's TV, an LG retailer, provides a full spec table corroborating verbatim: Place Settings 15, Silence Rating 42 dB, 3rd Rack System Yes, Wi-Fi Yes, Energy Star Certified Yes, and Dynamic Heat Dry (sale price $1,349.99). wash_cycles=6 counts the programs listed under the retailer's "Wash Cycles" label (Auto, Heavy, Delicate, Refresh, Normal, 1-Hour Turbo); the separately listed Download Cycle entries (Machine Clean, Rinse, Express) are not counted, consistent with catalog methodology. drying_type was trimmed to the verbatim "Dynamic Heat Dry" branding found on both pages; the original entry's parenthetical description ("circulates hot air throughout the dishwasher for faster, more complete drying") appears in neither fetched page and was removed as unsupported. release and releaseDate are null — no fetched page states a model launch year (LG's "Dynamic Heat Dry (2024)" note refers to the technology, not a verified model release date).
