Hello Carl.
There have been many advances and improvements in LG washers and every time that a new model succeeds the previous model, it improves on the older model. Without knowing what previous generation LG Front Load Washer you're referring to it's hard to say what those advancements are.
The LG - TurboWash 4.3 Cu. Ft. 12-Cycle High-Efficiency Steam Front-Loading Washer - Graphite Steel, Model WM3570HVA has a TUB CLEAN cycle that you should run once a week for three consecutive weeks should you notice mildew or musty smells which are a result of residue that has built up due to some environmental conditions or usage of the washer. The Washer also has a magnetic plunger that allows you to safely and conveniently secure the door slightly ajar to promote air circulation and help the machine to dry. Improper installation or use of the washing
machine in a humid space for a long period of time potentially could lead to a buildup of
detergent residue in the washing machine that may produce mildew or musty smells. Cleaning the washer tub on a monthly basis with the TUB CLEAN cycle will minimize the possibility that detergent residue will build up and mildew or musty smells may occur. Keep in mind that you also introduce Laundry bacteria when washing your clothes which may also contribute to mold and mildew build up. This washer also has a SANITARY cycle that is NSF International certified to reduce 99% of bacteria on laundry through high temperature when used with powdered detergents.
Another feature that probably was not on earlier washers is the Automatic Alert for cleaning the washer tub. The Automatic indication alert generally comes on every 1-2 months to indicate that the tub needs cleaning but this may vary depending on frequency of use.
Things that you can do to help preventing mold and mildew would be to keep the detergent dispenser drawer free of detergent residue by using a soft cloth or brush to clean out the residue. Periodically clean the tub about once a month and leave the door open after you do your laundry to help drying the tub out...IFV
