PARTS AND FEATURES
FEATURES
LARGE CAPACITY

LG dishwashers allow you to load very large items in both the upper and lower racks. The tall tub provides extra overall capacity and the clearance to accommodate large dishes. Extra-large items (max. 14 in.) may be loaded in the lower rack by raising the upper rack.
VARIO SPRAY SYSTEM

The water spray alternates between the upper and lower racks, so all of the power from the motor is directed to one rack at a time. This concentrates all of the cleaning power of the motor on each rack in turn.
SLIM DIRECT MOTOR™

The new Slim Direct Motor™ is inverter-controlled. Wash power is controlled based on cycle selection.
SOFT FOOD GRINDER AND SELF-CLEANING FILTER

For best wash results, your LG dishwasher has a built-in soft food grinder and a self-cleaning soft food and residue into small particles that can be flushed down the drain. The self-cleans the wash water as it circulates to separate any residue from the wash water. All dirt and residue easily washes down the drain.
HYBRID DRYING SYSTEM

This system effectively dries dishes without the use of a heating element that would increase energy consumption.

LOADING THE LOWER RACK
NON-DISHWASHER SAFE ITEMS
The combination of high water temperature and dishwasher detergents may damage certain items. LG does not recommend
washing the following items in the dishwasher:
- Hand-painted silver or gold leaf dishes
- Wood or bone-handled utensils
- Iron or other rust-prone utensils
- Plastic items that are not dishwasher safe
When in doubt, check the manufacturer’s recommendations. The extra-tall tub allows loading of dishes, pans, or other utensils up to 14 inches high. The lower rack is recommended for dinner plates, soup bowls, dishes, pots, pans, lids, and grill trays. Plates should be positioned vertically and facing the center of the rack. Pots, pans, and large bowls must be turned so that the inside faces downward. The silverware basket may be used in either the lower or upper rack.
RACK LOADING TIPS
LOADING 10 PLACE SETTINGS

- Load plates, soup bowls, etc., between the tines.
- Load cookie sheets, cakpansan, and other large items on the sides or back of the rack. Loading these items in the front of
The dishwasher can prevent the water spray from reaching the detergent dispenser. - Make sure that pot handles and other large items do not stop the rotation of the spray arms.

LOADING DISHES & POTS

LOADING POTS & BOWLS

LOADING THE SILVERWARE BASKET

The silverware basket has separators to avoid scratching and tarnishing of delicate silverware. The basket can be separated into three separate baskets that can be used individually in both the upper and lower racks. Unlock the tabs above the left and right sides separately.
SILVERWARE LOADING TIPS:
- For best cleaning results, use the top separators in the basket when loading silverware. The separators will prevent nesting of silverware.
- Load sharp items, such as knives, pointing down.
- When unloading the dishwasher, it is best to start with the silverware basket. Doing so will prevent water droplets from falling on your silverware from the upper rack.
HEIGHT ADJUSTABLE UPPER RACK
The upper rack adjusts up and down. Adjust the upper rack to allow tall and oversized items up to 14 inches high in the lower rack. Adjust the upper rack down to allow placement of large dishes up to 12 inches high in the upper rack. The upper rack comes in the upper position.

- To lower the rack: Hold the rack at the center of each side to support its weight. Then, lift the lever on each side to release the rack and lower it to the lower position.
- To raise the rack: Simply lift the rack at the center of each side (see illustration) until the rack locks into place in the upper position. It is not necessary to lift the lock levers to raise the rack.
LOADING THE UPPER RACK
Use the upper rack for small or delicate items such as small plates, cups, saucers, glasses, and dishwasher-safe plastic items. Cups, glasses, and bowls must be positioned upside down. Extra cups or cooking utensils can be laid on the fold-down cup racks, which may also provide support for long-stemmed glasses. Make sure items do not interfere with the rotation of the spray arms above and below the upper rack.
LOADING 10 PLACE SETTINGS

LOADING 12 PLACE SETTINGS

UPPER RACK LOADING TIPS:
- Place cups and glasses in the rows between the rack tines. Placing them over the rack tines can lead to breakage and water spots.
- To avoid chipping, do not let stemware touch other items.
- Place items so that the open end faces down for cleaning and drying.
- Do not stack items on top of each other.
LOADING THE CUTLERY RACK (on some models)

The cutlery rack is best suited for flatware and most cooking or serving utensils. Heavily soiled utensils or items with baked-on foods should be placed in the middle rack or spoon basket for best performance. The separators on the cutlery racks help keep flatware separated to avoid damage and improve cleaning.
CARE & CLEANING

LG LDS5540ST Dishwasher With Tub-FAQs
How do I perform a factory reset on my dishwasher?
Some models allow a factory reset by holding the Start/Reset button for several seconds. For others, turn off the power completely and restore it. This resets all settings to default.
Why is my LG dishwasher noisy?
Noise can result from misaligned spray arms, worn motors, or debris in the drain. Ensure the dishwasher is level and clean internal parts regularly.
How can I reduce dishwasher noise?
Load dishes correctly, avoid overloading, and ensure spray arms rotate freely. Use the Tub Clean cycle periodically to remove buildup.
How do I use the Tub Clean cycle?
Select the Tub Clean cycle, add the recommended dishwasher cleaner, and run the cycle empty. This removes grease, grime, and odors from the tub.
How long does a normal wash cycle take?
Cycles vary: standard wash takes about 2–3 hours, while Eco or Heavy Duty modes may take longer.
Can I use vinegar or baking soda in my LG dishwasher?
Yes, vinegar helps remove odors and buildup. Baking soda can freshen and aid cleaning, but avoid using them together at the same time.
How often should I clean the dishwasher filter?
Clean the filter at least once a month to maintain drainage and ensure optimal cleaning performance.
Why does my dishwasher take 3 hours to wash?
Eco-friendly modes lower water temperature to save energy, which extends cycle time. Use normal or quick wash for faster cycles.
How do I make my dishes shine in the dishwasher?
Use the correct detergent, avoid overloading, rinse heavily soiled items, and run the Rinse Aid function if available.
