LG Dishwasher Lines and Features
How LG Dishwashers Are Built
QuadWash models run four spray arms rather than two, so a blocked or damaged arm is one of several parts a tech checks for poor cleaning. Source: LG USA - 24 Inch Smart Dishwasher with QuadWash and Adjustable 3rd Rack, 44dB
LG Dishwasher Symptoms and First Checks
- Dishwasher making noise. LG treats fill whistling and some air-sucking sounds as normal, says rattling usually means loose dishes or an unseated filter, and flags squealing or grinding as a possible pump problem. Source: LG USA Support - LG Dishwasher Noises
- Dishwasher not cleaning. LG points first to scraping large food scraps and loading so dishes don't overlap or block the spray arms, then cleaning the filter and spray arms. Source: LG USA Support - Why Your LG Dishwasher Isn't Cleaning Dishes Well and How to Fix It

Local Notes for Highlands Ranch
Centennial Water and Sanitation District (Highlands Ranch Water), which supplies Highlands Ranch, reports hardness of usually 11-13 grains per gallon (about 188-222 mg/L), which the district classifies as hard. Hard water leaves spots and film on glasses and builds up on dishwasher spray arms and inlet screens, which is worth mentioning when you book a repair.
