Samsung vs LG Dishwasher: Which Is the Better Buy?
Samsung and LG are two of South Korea's biggest appliance brands and both have strong dishwasher ranges in Australia. While neither is traditionally the first choice over European brands like Bosch or Miele, both offer strong technology, good value and reliable performance. Here's how they compare.
Brand Positioning
Samsung
Samsung has pushed hard into the dishwasher market with innovative features and competitive pricing. Their dishwashers emphasise smart connectivity (SmartThings app integration), Zone Booster cleaning technology, and sleek design to match their other kitchen appliances.
LG
LG's dishwashers centre around the QuadWash system (four spray arms instead of two), TrueSteam technology for sanitisation and improved drying, and EasyRack Plus adjustable racking. LG also offers strong smart connectivity through their ThinQ app.
Key Comparison
| Feature | Samsung | LG |
|---|---|---|
| Signature technology | Zone Booster, SmartThings | QuadWash, TrueSteam |
| Spray arms | 2 (Zone Booster intensifies lower zone) | 4 (QuadWash) |
| Steam function | Some models | TrueSteam on most models |
| Smart connectivity | SmartThings (strong ecosystem) | ThinQ (strong ecosystem) |
| Noise level | 44–48 dB typically | 42–48 dB typically |
| Capacity | 13–14 place settings | 14–15 place settings |
| Price range (60cm) | $900–$2,500 | $900–$2,500 |
| Energy efficiency | 3.5–4.5 stars | 4–5 stars |
Cleaning Performance
Samsung Zone Booster
Samsung's Zone Booster allows you to intensify cleaning in the lower rack — useful for heavily soiled pots and pans while running a lighter cycle above. Their WaterWall technology (on some models) uses a sweeping water wall instead of rotating spray arms for even coverage. Performance is very good on standard loads.
LG QuadWash
LG's four-spray-arm system (two on the lower rack, one on the upper rack, one for the cutlery tray) provides more comprehensive water coverage, particularly on the upper rack and cutlery. This translates to better cleaning on full loads with items in every rack position. QuadWash is a genuine differentiator.
Drying Performance
Both brands use condensation drying. LG's TrueSteam function (available on most models) releases steam during the drying phase, which improves drying results on plastics and glasses — an area where condensation drying traditionally struggles. This is a meaningful advantage for LG in day-to-day use.
Smart Features
Both Samsung SmartThings and LG ThinQ app integration allow cycle control, monitoring and notifications from your phone. If you're already in the Samsung ecosystem (Samsung fridge, TV, phone), SmartThings integration across all appliances is seamless. The same applies to LG ThinQ.
Our Verdict
LG edges ahead for most buyers: QuadWash delivers more consistent cleaning results on busy racks, TrueSteam improves drying, and LG's dishwashers tend to be slightly quieter and more energy efficient. Samsung is a better choice if you're building a Samsung smart home ecosystem, or if you need Zone Booster for heavy lower-rack loads. Both are solid, reliable choices offering good value.
