Does not dry
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Wash is pretty good but does not dry the dishes, it leaves them wet and with water spots
No, I would not recommend this to a friendBrand response from LG Digital Customer Care
Posted .Hi, Lucio. Thank you for sharing your experience with the LG Dishwasher (LDFN4542S) model. We’re glad to hear the wash performance meets your expectations, though we understand your concern about the drying doesn’t deliver the same results—especially with lingering moisture and water spots. We strive to provide high-quality products that exceed our customer's needs and expectations.
This model uses LG’s Hybrid Drying system, which relies on the final rinse temperature and a fan-assisted process rather than a heated drying element. To improve drying results, we recommend: Using a rinse aid consistently (this makes a big difference). Selecting the “Extra Dry” or “High Temp” options, and opening the door slightly after the cycle to allow steam to escape. For more help, visit https://www.lg.com/us/support/help-library/lg-dishwasher-not-drying-properly--20150621962758. We’d love to help you get the best results possible—feel free to message us on social media @LGUSSupport for tailored tips or questions about your settings. We're here to help. ^Juvy
Do your homework before purchasing
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Extremely disappointed in this dishwasher, it does not have a heating element to heat the wash and rinse water and more importantly to dry the dishes. I would NOT recommend this dishwasher to anyone. Who manufactures a dishwasher with out a heating element. . . It does a nice cleaning job but you have to run your hot water to scalding before starting the wash cycle. Another issue is the bottom rack does not have enough tines.

LG 24" dishwaster
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Hate the top and bottom baskets. There are not enough prongs to hold up my glass such as wine glasses, and I have to lower the top baskets in order to wash glasses. IF I have lowered the top basket, the I can't wash my plates ... not enough room and the water spinner hits the plates.

It cleans the dishes
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.works ok but wash cycle is way too long - over 2 hours position of racks are not user friendly, cant get as many dishes in it as my previous one.
No, I would not recommend this to a friendThe Reviews don't match my experience
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Since getting this dishwasher, I have had issues with extreme noise. I reported it to Best Buy, who did nothing other than tell me to contact LG. I contacted LG, and they have had a service tech come out two times with no resolution. On the last visit, the service tech dented my front panel. I chose this brand and model based on the positive reviews, and I have never owned a dishwasher this noisy. I'm not sure what to do next.

Very disappointed
||Posted . Owned for more than 2 years when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.All my kitchen appliances are LG. But the dishwasher I would not recommend. After two years I started getting an A3 error, which means there’s a leak somewhere. I tried to turn the dishwasher off, but it automatically turned on by itself spraying water. LG wants to charge me $300 for service. I was not aware that the life of a LG washer is two years.

Does not dry dishes even on extra dry setting
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Does not dry dishes even on extra dry setting...better luck next time
No, I would not recommend this to a friendBrand response from LGAnswers
Posted .Drying performance is directly affected by the amount of heat that remains in the tub after the heated rinse is performed. If your dishwasher is far away from your home’s hot water heater, it may be necessary to run the hot water tap in the sink before starting a wash cycle, to ensure that cool water is purged from the hot water lines. This will ensure your dishwasher has a consistent supply of hot water from start to finish.
Using the High Temp setting also aids in keeping the inner drum temperature and dishes hotter before drying begins. LG dishwashers are designed to be used in conjunction with a rinse aid. Using a rinse aid will maximize the amount of water that has already been sheeted away from the dishes before the dry cycle begins. If a rinse aid is used and the performance still needs a boost, adjust the amount of rinse aid used. 2 is the default setting, but if necessary set the level to 3 so more rinse aid is used.
Water tends to bead rather than sheet of plastic and nonstick surfaces, making them more difficult to dry. If washing plastic items in a Normal cycle, select the Extra Dry or Night Dry option or both for better drying results. When the rinse aid is empty, the Extra Dry option is selected automatically.
Allow the dishwasher to completely finish the dry cycle before opening the door. If the door is opened in the middle of the dry cycle, the heat that is necessary for the hybrid dry system to work will escape. This will cause all of the dishes inside to remain wet once the cycle finishes. ^Jennifer
New to digital
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Really haven’t gotten used to my new high efficiency dishwasher!!
I would recommend this to a friendPathetic EXCUSE for a Business!
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.If there was a LOWER rating I could give to BEST BUY I would... After the first installers couldn't install, installation was rescheduled for a later date. When trying to verify my second installation date, I find that there was NO installation set, even though I have an email saying the installation was scheduled. This all leads to another LATER installation date. I can't tell you how INCOMPETENT BEST BUY HAS BECOME! Hopefully the third date will work and the installer can perform his JOB. Talking to TotalTECH was a complete failure, as they transferred me to a store for MORE HELP... The guy at the store wanted to give me another number to call... Absolutely incredible that BEST Buy is even in business as incompetent as this ONE SIMPLE purchase should have been. I can tell you one thing... After I get this done, my account will be closed and I will NEVER buy from BEST BUY again!

Buy with caution, Control Board Issues seem common
||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The dishwasher seems fine as functionality goes, but the reliability seems poor. It started having some control board issues in the 12th month of ownership and I was busy caring for a newborn, so I didn't get around to calling about the issue. I called the day after 1 year and I'm basically SOL (out of luck). Buy with caution, product seems great when it works, but the reliability is poor.

Noisy Dishwasher
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Too noisy! The rack doesn’t hold the plates still.
No, I would not recommend this to a friendBrand response from LG Digital Customer Care
Posted .Hello there, JennyM. We understand your inquiry about the LG 24″ Front-Control Built-In Dishwasher with QuadWash and 3rd Rack (model LDFN4542S) and appreciate you sharing your experience. It sounds like the noise level and plate stability in the rack are keeping your dishwasher from doing its best, and we’re here to help.
One helpful troubleshooting step is to first ensure that dishes and silverware are properly secured in the racks. Pause a cycle and check that no plates or utensils are protruding past the tines, as this can allow items to shift and rattle against the spray arms. You may also gently remove the bottom filter assembly—located at the base of the tub—rinse it under warm water to clear any debris, and reinsert it firmly; a clogged or loose filter can amplify rattling noises during operation.
If you’re still hearing excessive noise, try adjusting the water inlet valve to reduce water pressure slightly; sometimes high water flow can create a whistling or rattling sound as it enters the wash chamber. Finally, inspect the 3rd-rack rollers to ensure they’re aligned on the tracks—if any wheel appears misaligned, lift the rack off and realign the rollers before reinserting.

||Posted . Owned for more than 2 years when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Just over two years old and the electrical is randomly shutting off. Dishwasher before this one only lasted 4 years. Starting to feel like buying appliances is like buying new jeans. Geez! I have a stove that is over 25 years old in my daycare. Current stove convectional broke at month 11, and two washers during covid! And now this! Ridiculous. LG dryer still kicking after 17 years. LG was dependable. Was.

Save your money!!
||Posted . Owned for 8 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.If I could give this 0 stars I would! This machine has been nothing but a headache since the day we got it! It has a fault code & alarm every other load saying the reservoir underneath is full of water, and this was a known problem! Just wish I’d known before wasting my money! In addition to having to pull it out of the wall to fix it every time just to get it to work… the dry setting is a joke! This dishwasher doesn’t dry anything! The only way you’ll have dry dishes from this machine is to let them air dry with the door open or dry them yourself with a towel. Save your money! Do Not buy this dishwasher!

Disappointed
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Nice dishwasher but it doesn’t have heated drying which is disappointing. I assumed that was a standard thing.
No, I would not recommend this to a friendKeep looking
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought this to replace my dishwasher that worked but sucked. This one sucks too. The bottom rack will NOT stay on the track. It’s way louder than there one I had before and even though there’s way to lock the buttons, if you lean against it working at the counter your body hits buttons potentially turning it off.

Posted .Hello there, Cynthiah. Thank you for sharing your experience with us. We understand your situation, and we know how important it is for your dishwasher to provide excellent cleaning and drying results.
To help improve the cleaning performance, here are a few steps you can try:
Ensure Proper Loading: Avoid overlapping dishes and ensure that no dishes are in contact with the nozzles. Adjust the height of the racks to ensure no dishes block the spray arms, and load the cutlery in a standing position for the best performance.
Clean the Filter: Remove the lower basket and clean the filter to ensure it is free of debris. Improper installation can affect the wash performance, so make sure to reinstall the filter properly.
Run a Machine Clean Cycle: You can also perform a Machine Clean cycle by removing any dishes, filling the detergent dispenser with citric acid or a dishwasher cleaner, and running the cycle. This helps clean the interior and improve the overall performance.
For more detailed steps, you can check our Dishwasher Not Cleaning Help Guide.
