The short answer

GE 24" Portable Dishwasher with Sanitize Cycle comes out ahead by a narrow margin (4.6 vs 4.4). GE 24" Portable Dishwasher with Sanitize Cycle is best for: renters and small kitchens that want built-in-level cleaning without a permanent installation. Read the strengths below before deciding.

The GE GPT225SSLSS is a 24-inch convertible dishwasher with a stainless steel tub that rolls on casters and runs from a kitchen faucet, or can be fully installed. Reviewed found its cleaning and drying matched higher-end built-in machines, and Wirecutter names the GPT series its top portable pick for strong cleaning and an easy hook-up. Both note drawbacks: Reviewed measured heavy water use and a short cycle list, and Wirecutter points out it cannot run from a standard water line without extra plumbing. It suits renters and small kitchens with no dishwasher connection; anyone who can install a built-in machine, or who wants a tighter water budget, should look elsewhere.

Strengths
  • — Cleaned 98.5% of test stains on its Normal cycle and almost 99% on Heavy in Reviewed's lab
  • — Dries well, with only one or two items short of fully dry from a full load
  • — Input and output hoses come pre-attached, so hooking up to a faucet is quick
Watch-outs
  • — Reviewed estimates water use at over 1,394 gallons a year, more than twice a typical built-in
  • — Only three wash cycles and few ways to customise a wash
  • — Cannot connect to a standard water line without extra plumbing work
LG LDTH7972S
Ranked #3 in Best Dishwashers
LG LDTH7972S
2 sourcesall derived

The LG LDTH7972S is the value pick that doesn't feel like one. At $949 it matches the Bosch 800 Series on noise (42 dBA), beats most everything in its class on warranty depth, and is the only machine in this comparison with a true steam generator. The lower rack has a documented cleaning dead-zone, though on the Heavy cycle with TrueSteam the LG removes over 99% of stains.

Strengths
  • — TrueSteam loosens baked-on food before the main wash, raising Heavy-cycle cleaning past 99%
  • — 1-hour wash-and-dry cycle finishes a full load in under 60 minutes
  • — ThinQ Wi-Fi app with downloadable cycles, leak detection, and Alexa/Google voice
Watch-outs
  • — Bottom-center of the lower rack can leave heavier stains during Normal cycles (Reviewed measured up to 70% residual staining there in testing)
  • — Plastics still require a wipe after the dry cycle despite the Dynamic Heat Dry fan
  • — Only 1 year on parts and labor — the deeper warranties are on specific components

Derived means the reviewer published no score, so one was inferred from their written verdict. Everything else is a number the publisher printed. How we rank.

How they stack up

GE 24" Portable Dishwasher with Sanitize Cycle

Unlike the built-in LG LDTH7972S and Bosch 800 Series SHX78CM5N, the GE rolls on casters and connects to a kitchen faucet, and can later be converted to a permanent installation. It is a full 24-inch-wide machine, so it holds far more than the Farberware FCD06ABBWHA Countertop Dishwasher, but it needs floor space and a compatible faucet rather than a spot on the counter.

LG LDTH7972S

The LG LDTH7972S matches the Bosch 800 Series SHX78CM5N at 42 dBA and also offers Wi-Fi app control, but its lower rack has a documented cleaning dead zone on Normal cycles. Against the KitchenAid KDTM604KPS it has 10 wash cycles to 5 and carries a 10-year warranty on the direct-drive motor. It is far quieter than the 54 dBA Farberware FCD06ABBWHA Countertop Dishwasher and holds 15 place settings to the Farberware's 6.
