How to Clean an LG Dishwasher the Easy Way (Quick Steps)

It’s normal for dishwashers to get dirty over time. Many people forget that even high-tech LG dishwashers need regular cleaning. You can easily remove grime, soap buildup, and odor with the right steps.

Always remove leftover food and debris from the filter first. Wipe the door and edges with a soft cloth. Use a dishwasher cleaner or vinegar for deep cleaning. Regular maintenance improves performance, reduces odors, and prevents expensive repairs.

Best Ways to Clean Your LG Dishwasher Thoroughly

Inspect and Clean the Filter

First, locate the dishwasher filter at the bottom of the appliance. Carefully remove it by turning and lifting it out. Check for leftover food, grease, or grime stuck in the mesh. Rinse it under warm running water using a soft brush to remove all particles.

If food debris remains, soak the filter in warm, soapy water for 10–15 minutes. After soaking, gently scrub it again, then rinse completely. Never use harsh tools like knives, as they can damage the filter. Place the filter back properly to ensure water flows correctly during washes.

Cleaning the filter regularly prevents clogs, bad odors, and poor cleaning performance. It also protects the dishwasher’s pump and keeps your appliance running efficiently. You should check it at least once a week if you run dishes daily.

• Locate the filter at the bottom.
• Remove and rinse under warm water.
• Soak in soapy water if needed.
• Scrub gently and replace securely.

Wipe Down the Door and Seals

Next, open the dishwasher and examine the door edges and rubber seals. These areas collect dirt, soap scum, and mold over time. Use a damp cloth with mild soap to clean thoroughly. Wipe in small sections to avoid missing hidden dirt.

Pay attention to the gasket, as food particles can hide there. Clean slowly and carefully to prevent damage. After wiping, use a dry cloth to remove moisture, which can cause mold growth. This simple step helps your dishwasher stay hygienic and prevents bad smells from spreading.

Keeping the door and seals clean ensures a tight seal during operation. It also prevents leaks and keeps your appliance looking neat. Make this part of your weekly routine for the best results.

• Check edges and seals for dirt.
• Use a damp cloth with mild soap.
• Wipe small sections carefully.
• Dry completely to prevent mold.

Clean the Spray Arms

Spray arms distribute water for cleaning dishes. Over time, they can get clogged with food or mineral deposits. Remove the arms by unlocking or unscrewing them carefully. Inspect all holes to make sure they are clear.

If you notice blockages, use a toothpick or small brush to remove debris. Rinse under warm water, ensuring all holes are free. For tough mineral buildup, soak the spray arms in vinegar for 20–30 minutes. Reattach them securely before running the dishwasher again.

Regular cleaning of spray arms improves water flow and ensures dishes come out spotless. It also extends the life of your dishwasher by reducing strain on the pump. Clean them monthly for optimal performance.

• Remove spray arms carefully.
• Check all holes for clogs.
• Use vinegar for mineral buildup.
• Reattach securely before use.

Run a Cleaning Cycle with Vinegar

Once the parts are clean, it’s time for a full internal cleaning. Place a cup of white vinegar in a dishwasher-safe container on the top rack. Run a hot water cycle without any dishes. The vinegar helps remove grease, odors, and mild stains inside the machine.

This method also cleans the internal pipes and removes light mineral buildup. Avoid using harsh chemicals, as vinegar is safe and effective for regular maintenance. After the cycle, leave the door open for a few hours to allow the interior to dry completely.

Using vinegar is an eco-friendly and inexpensive way to maintain your dishwasher. Repeat this process monthly or when you notice odors or buildup. Regular cleaning keeps your LG dishwasher performing like new.

• Place a cup of vinegar on the top rack.
• Run a hot water cycle without dishes.
• Allow the dishwasher to dry with the door open.
• Repeat monthly for maintenance.

Use a Dishwasher Cleaner for Deep Cleaning

For stubborn buildup, a commercial dishwasher cleaner works best. These cleaners are designed to remove hard water deposits, grease, and soap scum. Follow the manufacturer’s instructions carefully. Place the cleaner in the detergent compartment or as directed.

Run a full cleaning cycle without dishes. This process reaches areas that vinegar alone might miss. After the cycle, check for any remaining residue and wipe if necessary. Regular deep cleaning keeps your dishwasher efficient and odor-free.

Using a commercial cleaner occasionally ensures thorough sanitation and removes hidden deposits. This step is especially useful if your dishwasher is used heavily or in hard water areas.

• Use a cleaner as instructed.
• Run a full cycle without dishes.
• Wipe remaining residue.
• Repeat every 1–3 months depending on use.

Maintain the Exterior and Controls

Finally, don’t forget the outside of your dishwasher. Wipe the door, handle, and control panel with a damp cloth and mild soap. Avoid abrasive cleaners or rough sponges that can scratch the surface. Dry immediately to prevent streaks and water spots.

Check for buttons or displays that may have trapped dirt. Clean gently using a soft cloth or cotton swab. Maintaining the exterior not only keeps it looking new but also ensures controls work properly without interference from grime.

Regular exterior cleaning complements internal maintenance and prolongs the appliance’s life. Make it a simple weekly routine to keep your LG dishwasher clean and attractive.

• Wipe door, handle, and panel with a damp cloth.
• Avoid abrasive cleaners.
• Dry immediately to prevent streaks.
• Check and clean buttons if needed.
