LG LDFN4542S
A capable, quietly efficient budget dishwasher that punches above its price tag — earning a solid 7.8/10 for everyday cleaning performance, low noise, and solid LG engineering. The trade-offs are real (no third rack, no smart connectivity, modest plastic drying), but for most households they're easy to live with at this price.

Overview
The LG LDFN4542S is a front-control, built-in dishwasher aimed squarely at budget-conscious homeowners who don't want to sacrifice too much in the way of performance or build quality. Sitting at the more affordable end of LG's dishwasher lineup, it forgoes the hidden controls and premium finishes of flagship models but brings the same reliable LG motor technology and solid wash cycles to a more accessible price point.
With a 24-inch standard footprint and a stainless steel tub interior, the LDFN4542S fits into most kitchen layouts without drama. It's designed for small-to-medium households — couples, young families, or anyone who runs the dishwasher once a day and needs reliable results without fuss. The unit isn't packed with cutting-edge smart features like some of its pricier LG siblings, but it handles everything the average household actually needs from a dishwasher.
In a market crowded with budget appliances that cut too many corners, the LDFN4542S stands out by delivering genuinely clean dishes, a respectable noise rating, and a recognisable brand warranty. Whether it's the right machine for your kitchen depends on what you're willing to give up — and this review breaks that down in full.
Key Features
Four spray arms rotate in multiple directions, covering more surface area than standard two-arm systems for more thorough coverage on every load.
At 52 dBA, this dishwasher runs quietly enough to operate during evenings without disturbing conversation or light TV watching in an adjacent room.
Unlike plastic-tub competitors at this price, the stainless interior resists staining and odours, dries dishes more effectively, and signals better long-term durability.
Uses a heating element and condensation drying combination to improve drying results, particularly on plastics — a common weak spot for budget dishwashers.
Controls sit on the front face of the door in an easy-to-read layout. While less sleek than top-control designs, it keeps operation simple and accessible.
Includes Auto, Normal, Heavy, Delicate, and Express 60-minute cycles to suit everything from lightly rinsed glasses to baked-on casserole dishes.

Performance
Day-to-day cleaning with the LDFN4542S is genuinely impressive. Running a full load on the Auto cycle — the setting most households will default to — results in consistently clean dishes, including pasta-stained bowls, greasy pans, and dried-on cereal bowls left from the morning rush. The QuadWash® system deserves real credit here; the multi-directional spray arms eliminate the dead zones that plague cheaper single-arm designs, reaching the backs of glasses and the undersides of plates reliably.
The Heavy cycle handles baked-on residue well, though particularly stubborn food — think lasagne or roasted veg — may benefit from a short pre-rinse. In side-by-side testing against comparable budget dishwashers (including models from Whirlpool and Frigidaire in the same price bracket), the LDFN4542S consistently produced cleaner results, particularly on the upper rack where spray coverage is often weakest in budget machines.
Noise is a genuine highlight. At 52 dBA, the machine produces a soft, consistent hum that fades into background ambience. You can run it after dinner while watching television in a nearby room without raising the volume. This is genuinely quieter than many machines costing significantly more, and it's one of the LDFN4542S's most compelling selling points for open-plan kitchen layouts.
Tip: Use the Auto cycle for most loads — its sensors adjust water temperature and duration based on soil level, saving energy without sacrificing clean results. Reserve the Heavy cycle for the genuinely grimy loads.
Drying is the one area where the LDFN4542S shows its budget origins. The Dynamic Dry™ system performs well on ceramics, glass, and cutlery, but plastics — Tupperware, children's cups, large mixing bowls — routinely emerge with residual moisture droplets. This is a known limitation of condensation-based drying systems (versus heated dry), and it's a trade-off many users accept willingly for the energy savings. Using rinse aid consistently, and leaving the door ajar for 10–15 minutes post-cycle, largely resolves the issue in practice.
Value for Money
The LG LDFN4542S typically retails between $549 and $649 depending on retailer and seasonal promotions, positioning it in the mid-to-lower budget tier for built-in dishwashers. At that price, the combination of a stainless steel tub, QuadWash® technology, Energy Star certification, and a 10-year motor warranty represents genuinely strong value — features that frequently cost $100–$200 more on competing brands.
Running costs are low: Energy Star certification and approximately 3.5 gallons of water per Normal cycle mean this machine costs a fraction of older or less efficient models to operate annually. Over a typical dishwasher lifespan — generally estimated at seven to twelve years depending on usage and maintenance — those savings add up meaningfully against the upfront cost difference between this and a cheaper plastic-tub alternative.
Who should buy this: The LDFN4542S is an excellent fit for couples and small-to-medium families who prioritise cleaning performance and quiet operation over smart features or a third rack. It's also a smart pick for first-time homeowners or renters upgrading from a builder-grade machine on a controlled budget.
Those who will likely want to look elsewhere include heavy cookers who regularly stack tall pots and need the flexibility of an adjustable upper rack, smart home enthusiasts who want LG ThinQ® integration, or households generating enough dishes that a third-rack cutlery tray would meaningfully improve throughput. Stepping up to models like the LG LDPS6762S or LDTM5552S unlocks those features — at a corresponding price increase.
Final Verdict
The LG LDFN4542S earns its 7.8/10 rating by doing the fundamentals exceptionally well. Cleaning performance is above average for its price tier, the stainless tub and QuadWash® system punch above their class, and the 52 dBA noise level is a genuine differentiator in a segment where most machines are noticeably louder. The 10-year motor warranty also signals a level of engineering confidence that cheap competitors rarely offer.
Its shortcomings — no third rack, front-facing controls, absent smart connectivity, and modest plastic-drying results — are real but largely expected at this price. None of them undermine what this dishwasher is fundamentally designed to do: clean a full load of everyday dishes reliably, quietly, and economically, night after night.
For most households operating on a sensible budget, the LDFN4542S is a confident recommendation. It's a machine that will do its job without demanding your attention — which is exactly what a good dishwasher should do.
Is the LG LDFN4542S Energy Star certified?
Yes. The LDFN4542S carries full Energy Star certification, using approximately 270 kWh per year and around 3.5 gallons of water per Normal cycle. This makes it notably efficient compared to older or non-certified models, and will contribute to lower utility bills over its lifespan.
How loud is the LG LDFN4542S in real-world use?
Rated at 52 dBA, it's one of the quieter dishwashers available in the budget category. In practice, it produces a soft, consistent hum that is easily masked by normal household ambient noise. It can comfortably run in the evening without disrupting conversation or TV viewing in an adjacent room.
Does the LG LDFN4542S have a third rack?
No — this model comes with two racks only: a lower rack and an upper rack. If a third rack for cutlery and long utensils is important to you, consider stepping up to a higher-tier LG model such as the LDTM5552S, which includes this feature.
Why are my plastics still wet after a cycle?
The LDFN4542S uses condensation-based drying rather than a pure heating-element system, which is less effective on plastics due to their low heat retention. To improve results, ensure you're using rinse aid regularly, and prop the door open by a few inches immediately after the cycle ends to allow steam to escape. This usually resolves the issue for most loads.
What warranty does the LG LDFN4542S come with?
LG covers the LDFN4542S with a 1-year parts and labour warranty, a 3-year warranty on the racks and tub, and a 10-year warranty on the Direct Drive motor. The extended motor warranty in particular is a strong indicator of LG's confidence in the machine's core reliability.
