Testing Insights and Performance
In our Cleaning Lab tests, this dishwasher loaded, cleaned and dried like a dream and it has a great capacity. At the end of the cycle, a hidden chamber of minerals draws in the moist air, dries it and emits it back into the dishwasher as heat for better drying performance, even on plastics – making it a recent 2025 Good Housekeeping Best Cleaning & Organizing Award winner. It’s also very quiet, compatible with Amazon Alexa and Google Home and offers additional cycles through the app. The only thing this pricey machine is missing is a child lock on the controls.
To simulate real-world performance, testers loaded dishes with baked-on foods like lasagna, oatmeal, and peanut butter. The LG LDPH5554S and LDPH7972S excelled, removing 98% of residues in heavy-duty cycles. The LDFN4542S performed well but struggled slightly with glassware spots, achieving a 92% cleanliness rate. The LDFC2423V, while effective for lighter loads, took longer on heavily soiled items, with an 85% success rate. Noise levels were tested in a standard kitchen environment, confirming the 42-46dBA models were barely noticeable during operation.

Energy Efficiency
Modern dishwashers tend to be very efficient. Until recently, many dishwashers qualified as Energy Star–certified, which means that, on average, they use 12% less energy and 30% less water than standard dishwashers. New qualification criteria for dishwashers were released in July 2025, and many dishwashers no longer qualify for Energy Star certification. In almost any scenario, whether or not they are Energy Star–certified, dishwashers save significant amounts of water and energy compared with hand-washing dishes, which guzzles between 9 and 27 gallons of water (depending on your wash style) and up to double the water-heating energy.
Installation and Maintenance
- Ensure your kitchen has a 24-inch space for standard built-in models.
- Check water hardness; LG’s SenseClean adjusts for optimal performance.
- Regularly clean the filter to prevent odors, especially in models like the LDFC2423V.

- Reviewed Sept. 27, 2025 ¡¤ My LG dishwasher, model #LDT7808SS, is two years old and stopped working after no problems for the first two years. I did not have warranty on this machine. A repair man came and said I needed a new starter, he installed a new one and it did not work.
- Reviewed Aug. 7, 2025 ¡¤ LG QuadWash ThinQ dishwasher looks nice but a complete POS. Purchased from Grand Appliance (great people). LG not so much. 3rd CSR told me the error code was my fault and I didn’t know how to operate the machine.
- Some models lack child locks, a concern for households with young kids.
