I bought my first LG dishwasher after the old one flooded my kitchen floor three times in one month. I was tired of scrubbing plates by hand, so I took the plunge on a model with a stainless steel tub. It felt like a spaceship compared to my last machine, but once I learned the quirks, it made my kitchen routine much easier. You will get great results if you follow these steps.
You should load the bottom rack with your largest plates and heavy pots facing the center sprayer for the best clean. Always add a rinse aid to prevent water spots on your glassware. Select the Auto cycle for most loads, close the door firmly, and press start. If you hear a series of beeps, check the display for a code that shows a potential clogged drain filter or low water pressure. Keep the spray arms clear of large items so the water flows freely over every dish.
Understanding Your LG Dishwasher Features
Using an LG dishwasher is not just about pressing a button. You need to know how the racks move, where the soap goes, and why the steam cycle options change your wash.
Rack Adjustment Tips
The top rack moves up or down to give you more room for tall items. I use the lower setting when I wash my big stockpot or tall wine glasses. Just pull the side levers up to unlock the rack, slide it into the new position, and snap it back into place. It takes ten seconds once you practice it a few times.
Detergent Compartment Use
Only use high quality pods or liquid soap in the dispenser. I once used too much soap, and the machine left a film on everything. Fill the main cup to the line, close the lid until it clicks, and make sure the door stays dry. Moisture inside the cup causes the soap to clump before the cycle starts.
Spray Arm Maintenance
Water comes out of these arms at high pressure to clean your dishes. If a seed or piece of plastic gets stuck in the nozzle, the water flow drops. I check mine every month for debris. Pull the bottom arm off, rinse it under the sink, and poke any trapped bits out with a toothpick or small wire.
Filter Cleaning Process
The filter sits at the bottom of the tub. It catches all the food bits you missed before rinsing. Pull the circular part out by twisting it left. Rinse it under hot water, scrub it with a soft brush, and put it back. A dirty filter causes a nasty odor that stays in the machine.
Rinse Aid Importance
Water spots happen when your water is too hard or the dry cycle ends too early. Pour rinse aid into the small reservoir next to the soap cup. The light on the front will blink when it needs more. I fill mine once a month, and it makes my glasses look brand new every time.
Sensor Cycle Logic
LG machines have a sensor that checks how dirty the water is during the first wash. It adjusts the time and temperature based on that data. This means a half load might finish faster than a full one. Let the machine decide the time for you to save energy and water.
Actually, let me back up a second. Make sure you don’t overfill the bottom rack, or the middle sprayer won’t reach the cups. I learned that the hard way when my mugs came out with dry patches.
- Load dirty faces toward the center.
- Do not block the detergent door.
- Use a rinse aid for dry dishes.
- Clean the filter every two weeks.
- Check the spray arm for blockages.
- Run a cycle empty with vinegar.
Best Practices for Loading and Cycles
Loading an LG dishwasher is a bit like a puzzle. You want to fit as much as possible, but you must leave space for the water to hit every single surface.
Efficient Plate Arrangement
Place your dinner plates in the bottom rack, facing the center, so the water hits the food directly. Leave a small gap between each plate. If you push them too close, the water gets trapped between the surfaces. This leaves dried food residue that you have to scrub off later.
Proper Silverware Loading
Put your forks and spoons in the basket with the handles down, but keep knives pointing down for safety. I try to mix the types of silverware in each slot. If all the spoons nest together, they never get clean. The water needs to touch every side of the metal for a good result.
Large Item Placement
Big pots go on the bottom rack, but never block the detergent door or the spray arm. I tilt my bowls at an angle so water runs off the back during the rinse. If you place a bowl flat, it acts like a bucket and fills with dirty, soapy water.
Glassware Rack Safety
Put all your glasses in the top rack to keep them safe from high heat. I use the foldable tines to keep mugs steady so they do not bang against each other. If glasses touch, they might chip. Keep them separated by at least half an inch for the best results.
Cycle Selection Guide
The normal cycle is fine for daily dishes, but use the heavy cycle for baked-on grease. I always use the high heat option if I have greasy pans. It melts the fat away better than warm water. Avoid the quick cycle for heavy loads, as it does not clean enough.
Drying Performance Tips
Always use the extra dry setting if you want plastic containers to be completely dry. I open the door slightly when the cycle finishes to let the steam escape. This prevents water from condensing back onto the dishes as the machine cools down. It is a small trick that helps a lot.
- Tilt bowls to prevent pooling.
- Mix silverware to stop nesting.
- Use heavy cycle for grease.
- Keep plastics on the top.
- Open door after wash ends.
- Don’t block the soap door.
If you have a very heavy load, try to run it during the night when you aren’t using the kitchen. I noticed that my machine runs quieter, and the dishes have more time to air dry before I put them away in the morning.
Why Does My Dishwasher Smell Bad?
A bad smell is almost always a sign of trapped food or standing water. Check the filter first, because bits of old onion or grease often get stuck there. If the filter looks clean, check the door seal for hidden mold.
Wipe the rubber gasket with a damp cloth every week. Sometimes food gets lodged in the fold of the rubber and starts to decay. This causes a sour smell that fills the whole kitchen. You should also run a cleaning cycle with a cup of vinegar.
Place the vinegar in a bowl on the top rack and run the hottest cycle. Do not add any other soap or dishes during this wash. The vinegar breaks down mineral buildup and grease that sticks to the inside of the tub.
If the smell stays, you might have a drain hose problem. Sometimes the hose does not have a high loop, so sink water flows back into the machine. That backflow causes a nasty, swampy odor that is hard to get rid of.
- Clean the filter weekly.
- Wipe door seals often.
- Use vinegar for cleaning.
- Check the drain hose.
- Don’t leave dishes dirty.
- Run hot cycles regularly.
How to Handle Error Codes
Seeing a blinking light or a code on the screen can feel scary. Most LG error codes are actually quite simple to fix yourself. An OE code usually means the water is not draining.
Check the drain hose under your sink for any kinks or clogs. If the hose looks fine, look at the garbage disposal connection. Sometimes a small piece of food blocks the hole where the dishwasher hose meets the disposal.
If you see an AE or E1 code, it means there is a leak in the base of the unit. This happens if you use too much soap or if a seal has failed. Turn off the power immediately and check the bottom tray for water.
Always look up the specific code in your manual, because they vary by model. I keep a copy of my manual in a kitchen drawer for quick access. It saves me from calling a repair person for a tiny fix.
- Check for hose kinks.
- Clear the drain path.
- Turn off the power.
- Dry the base tray.
- Inspect door gaskets.
- Use the correct detergent.
What Causes Water Spots on Dishes?
Water spots happen when your water has too many minerals like calcium or magnesium. These minerals stay on your glasses after the water evaporates. This is why a rinse aid is so important for every single wash.
You should adjust the rinse aid dispenser setting if you still see spots. Most LG dishwashers let you change the amount of rinse aid released during the cycle. Check your manual to see how to increase the dosage.
If you have very hard water, consider using a high-quality dish detergent that contains enzymes. These enzymes break down the minerals before they settle on your clean plates. I switched brands, and it made a big difference.
Another factor is the heat of the water. If the water is not hot enough, the soap does not dissolve well. Run your kitchen sink faucet until the water is hot before starting the dishwasher cycle.
- Adjust rinse aid level.
- Use hot water start.
- Switch detergent brands.
- Check the spray arms.
- Clean the filter monthly.
- Use a drying agent.
Can I Use My Dishwasher for Other Things?
You can definitely wash more than just dishes in your LG machine. I use mine to clean my refrigerator shelves and plastic vegetable bins. Use the gentle cycle so the plastic does not warp under extreme heat.
I also clean my kitchen tools like sponges and scrub brushes on the top rack. High heat kills bacteria that hides in the sponges. Just make sure the items are dishwasher safe before you put them in.
Some people even wash baseball caps or plastic toys in the dishwasher. Put the caps on a special frame to keep their shape. Keep small toys in a mesh bag so they do not fall to the bottom.
Never put wood or cast iron in the machine. The heat and water will ruin the wood finish and strip the seasoning off your pans. Stick to glass, metal, and heavy plastic for the best results.
- Clean fridge shelves.
- Sanitize kitchen sponges.
- Wash hats with frames.
- Use a mesh bag.
- Keep wood out.
- Stick to safe plastics.

Frequently Asked Questions
Is It Safe to Use Dish Soap in My Dishwasher?
No, never use hand dish soap. It creates too many bubbles and can overflow, which might ruin your floor or break the machine motor. Always use detergent made specifically for dishwashers.
Can I Wash Cast Iron Pans in My LG Dishwasher?
No, you should avoid this. The harsh detergents and high heat will strip the protective seasoning off your pans. This causes rust to form, and it ruins the surface of your cookware.
Are There Specific Detergents for LG Models?
No, you do not need a special brand. However, you should use high quality pods or tablets. I suggest picking a brand that has a good reputation for dissolving fully in short cycles.
Do I Need to Rinse Dishes Before Loading Them?
No, you do not need to rinse them. Modern machines have sensors that detect food. Just scrape the large chunks of food into the trash or compost bin before you load them.
Should I Keep the Door Cracked After a Wash?
Yes, it is a great habit. Keeping the door open a few inches allows moisture to escape. This prevents mold and helps your dishes air dry completely without any musty smell.
Will My Dishwasher Clean Better with Hotter Water?
Yes, it will. Higher temperatures help dissolve grease and soap better than lukewarm water. Running the sink faucet until it gets hot before starting the machine ensures the best cleaning.
How Long Does an LG Dishwasher Usually Last?
Most machines last about ten years if you maintain them well. Cleaning the filter and checking the spray arms for debris are the best ways to extend the machine life.
Does the Machine Use Less Water Than Hand Washing?
Yes, it uses much less water. Modern dishwashers are designed to reuse water during the wash cycle. Hand washing often uses more water because the tap runs the entire time.
