Dishwasher 
If your LG dishwasher runs full cycle and dishes still come out dirty, thats a common complaint I hear.
From field jobs, this is often a basic cleaning/usage issue, not full machine failure.
Do these steps one by one.
1. Clean the Spray Arms
Those small spray-arm holes clog over time. Once they clog, dishes on corners stay dirty.
Take spray arms out carefully. Check holes under a bright light. You can use a toothpick or pin to clear blocked holes. Rinse well and install again.
Spin them by hand before closing door. They should move free and not touch dishes.
2. Check the Detergent
Detergent quality matters more than most people think. Moist or old pods dissolve poorly.
Use fresh dishwasher detergent only. Never use dish soap. You can add rinse aid, no problem in that. Many people skip it, but it really helps cleaning and drying.
I had a West Houston customer last week with dirty cups every cycle. We switched to fresh detergent and filled rinse aid, problem improved same day.
3. Load Dishes the Right Way
Overloading blocks spray path, then even good detergent cant do much.
Keep small gap between plates and bowls. Face dirty side to center.
Quick check: spin spray arm once before start. If it hits anything, rearrange items.
4. Make Sure Water Is Hot
LG dishwashers clean better with hot water, especially greasy dishes. Before starting, run the kitchen tap until water gets hot.
A good water-heater setting is around 120°F (49°C).
5. Remove Hard Water Buildup
Hard water minerals build up inside dishwasher over time.
This can reduce spray power and leave white film on glasses. Run an empty hot cycle with dishwasher cleaner once a month.
You can also run empty cycle with white vinegar in a bowl on lower rack.
In a Pearland home, hard-water buildup was the main issue. After internal cleaning, glasses were much clearer.
6. Check the Door Seal
Door gasket helps keep proper pressure inside. So, check full edge for cracks, gaps, or grease dirt.
If seal is worn, replacement is usually low cost and simple job.
If these steps still do not fix your LG dishwasher, then next checks are inlet valve, circulation pump, or control board.
If needed, we can inspect quickly and confirm the exact fault before any major repair.
