I remember standing in front of my first fancy dishwasher, staring at a blank black panel and wondering if I needed a degree in computer science just to wash a dinner plate. LG machines are great, but their hidden touch controls can be a little confusing if you are used to a simple mechanical knob.
Once you learn the secret to the hidden display, you will find it is actually a breeze to use. I am going to walk you through the exact sequence to get your machine running so you can stop guessing and start cleaning your dishes tonight.
You need to load your dishes, add the detergent, and close the door firmly. Once the door is latched, find the hidden control panel on the top edge of the door. Press the Power button, select your wash cycle, and press Start. Finally, close the door within four seconds to trigger the machine to begin its cycle.
Understanding Your LG Dishwasher Controls
LG dishwashers keep the buttons hidden on top of the door, which looks sleek but can be frustrating if you have never used one before. Here is how to find your way.
The Power Button
This button sits on the far left side of the top control panel. Press it once to wake the system. You will hear a soft chime and see the cycle lights glow. If the lights do not come on, check the breaker box in your garage. Sometimes a blown kitchen fuse will stop the machine cold. It happens to the best of us.
The Cycle Selection
You have several buttons for different wash intensities like Normal, Heavy, or Delicate. Choose one based on your current load. I usually stick to Normal for daily use. If you see a light blinking, that means the dishwasher cycle not starting properly. Just reset the power and pick the cycle again. Keep it simple and focus on the basics.
The Display Window
The small screen shows the estimated time left in the wash. It is helpful to know if you are in a rush. If the screen shows a code, that is a warning. Maybe the door is not latched or the water line is kinked. Don’t panic. Most of these display errors mean you skipped descaling for over a year and need a cleaning.
The Delay Start
This button lets you time your wash for later. I use it to run the machine during off-peak energy hours at night. Press the button once for every hour you want to wait. It keeps the kitchen quiet while I work or sleep. It is a nice feature if you want to avoid the loud dishwasher noise during dinner.
The Extra Options
Buttons like Extra Dry or Steam help clean stuck-on food. I use Steam for greasy baking sheets. It does a better job than a standard rinse. Just be careful with plastics. High heat can warp them if they sit too close to the bottom heating element. Always place your plastic containers on the top rack.
The Start Button
This button is the final step before the magic happens. After you pick your cycle and settings, press Start. The machine will beep. Now you have a few seconds to close the door tight. If you wait too long, the machine will cancel the command. You will have to repeat the steps. It is a common dishwasher mistake for beginners.
Actually, let me back up a second. Make sure the water supply valve is fully open under your sink. If you recently moved in, check that valve. It is often closed by default.
- Check that the spray arms spin freely.
- Ensure no tall items block the detergent door.
- Clean the filter if water is cloudy.
- Use high-quality rinse aid every month.
- Keep the edges of the door clean.
- Watch for a leaking dishwasher door seal.
How to Properly Operate Your LG Dishwasher
The secret to a successful wash is all in the timing and the setup. You have to follow the specific order of operations to ensure the cycle actually triggers correctly every single time.
Prepare the Machine
Before you touch any buttons, scrape the large food chunks off your plates. You do not need to rinse them perfectly, but big bones or corn cobs will clog the filter. Check the bottom of the tub for any debris. A clean filter ensures the water circulates efficiently. It prevents that gross smell you get from old food.
Make sure your detergent is fresh. I keep my pods in a sealed container under the sink. Humidity is the enemy here. If the pods get damp, they clump together and do not dissolve. That leaves a soapy mess on your clean dishes. Always dry your hands before reaching into the detergent box or the bag.
Finally, organize your rack carefully. Do not nest bowls inside each other. Water cannot reach the inside of nested items. Point your dirty surfaces toward the center spray arm. That is where the most pressure hits. If you crowd the rack, the water cannot move around. You will end up with dirty plates and wasted soap.
Select the Right Cycle
Now that the machine is loaded, press the power button on the top edge. It will chime. Select your cycle next. Most of my daily dishes go on the Normal cycle. It uses less water and energy than the Heavy setting. I save the Heavy setting for my Dutch oven or really greasy roasting pans.
If you have delicate glassware, look for the Delicate cycle. It uses lower water pressure and a gentler temperature. I have broken too many wine glasses by being impatient. Never mix delicate crystal with heavy steel pots. The vibration alone can cause them to knock into each other. It is not worth the risk of losing a favorite glass.
You can also customize the settings. I often add the Extra Dry option to my cycle. It helps my plastic containers dry faster. If I skip this, I usually have to towel-dry them by hand. That defeats the purpose of having a machine do the work for me. Check your manual for the best setting for your specific items.
Start the Wash Sequence
Once your cycle is selected, press the Start button. You will hear a single beep. That is the signal to close the door. You have about four seconds to get the door latched. If you close it too slowly, the machine will not lock in the command. You will hear a chime indicating it failed.
Wait for the lock to engage. You should hear a solid click. If the cycle is running, you will see a small light on the front panel or hear the water begin to spray inside. If the unit stays silent, open the door gently and check the display. It might be showing an error code if the door is not tight.
I usually walk away once I hear the water start. It is tempting to hang around, but the machine needs to do its work. Keep the door closed until the cycle finishes completely. Opening it mid-cycle lets all the steam out. That steam is necessary for the drying phase. It is a major dishwasher efficiency loss to open it too soon.
- Select the cycle before closing the door.
- Press the Start button firmly until it beeps.
- Close the door within four seconds exactly.
- Listen for the water to start flowing.
- Do not force the door handle shut.
- Wait for the cycle to end fully.
Getting the sequence right is the difference between a clean kitchen and a pile of wet, soapy dishes. Always double-check that your door is clicked shut. If the light does not come on after ten seconds, it did not start.
Dealing with Dishwasher Start Issues
If your LG machine refuses to start, check the power first. Most people assume the worst when the lights stay off, but it is usually just a tripped breaker in the utility closet. Check your electrical panel to see if a switch flipped off. Also, look at the door latch. If the hook is bent or caked with dried food, the sensor will not register that the door is closed. Clean the latch area with a damp cloth and try again.
Sometimes the child lock feature is active. You will see a small icon on the display, usually a lock symbol. This prevents anyone from starting the machine. To turn it off, hold the button labeled “Child Lock” or “Temp” for three seconds. The light should turn off. This is a common point of frustration for parents who accidentally hit it while leaning against the door.
If the buttons beep but the cycle does not begin, the control board might be stuck. Unplug the machine from the outlet for five minutes. This performs a hard reset on the computer inside. Plug it back in and try to select your cycle again. This clears minor glitches. It is a quick fix for a dishwashers not responding to touch inputs.
Lastly, make sure your water supply is flowing. If you just had plumbing work done, check the shut-off valve under the kitchen sink. If that valve is closed, the machine will detect no water and refuse to start the cycle to protect the motor. Open it slowly and listen for the water to hiss into the lines.
- Check the circuit breaker for power.
- Clean the latch if it is sticky.
- Disable the child lock settings.
- Perform a hard reset by unplugging.
- Ensure the water valve is open.
- Contact support if an error code persists.
How to Maintain Your LG Dishwasher Filter
The filter is the unsung hero of your dishwasher. It sits at the bottom of the tub, right under the bottom spray arm. If it gets clogged with grease and bits of paper, the water cannot drain or circulate. You should pull this out once a month. It twists out easily. Scrub it with a soft brush and warm soapy water to remove the film.
Do not use harsh chemicals on the filter. A little dish soap works wonders. If you see hard water buildup, soak the filter in white vinegar for an hour. This breaks down the minerals that make the mesh look white or cloudy. Rinse it thoroughly after soaking. Putting a dirty filter back in ruins all your hard work.
Check the drain pump area while the filter is out. Sometimes a piece of broken glass or a toothpick hides in there. Remove any debris you find. This prevents the pump from jamming. A jammed pump is the most common cause of a dishwasher not draining properly. Keep this area clear, and your machine will last for many years.
I always check the spray arm holes too. Sometimes hard water clogs them. Use a toothpick to poke through any blocked holes. This restores the water pressure to your wash. It makes a huge difference in how clean your plates come out. It only takes a minute to do this while the filter is soaking.
- Twist the filter counter-clockwise to remove.
- Wash the mesh with warm soapy water.
- Use a brush for stubborn grease.
- Soak in vinegar for hard water.
- Clear the drain area of debris.
- Poke spray arm holes with toothpicks.
Why Your Dishwasher Smells Musty
A smelly dishwasher is a sign that food particles are rotting in the filter or the door seal. I had this happen once after a week of vacation. The smell was awful. Start by cleaning the filter as described above. Then, wipe down the rubber seal around the door. That is where mold likes to hide. Use a vinegar solution to kill any bacteria.
Once the filter and seal are clean, run an empty cycle with a cup of baking soda. Pour it into the bottom of the tub. Do not put it in the soap dispenser. Run a hot cycle. This neutralizes odors. After that, run a second cycle with a cup of white vinegar. This cuts through any remaining soap scum.
Avoid leaving dirty dishes in the machine for days. If you only run the dishwasher once every three days, the food will start to stink. If you cannot run a full load, use the rinse-only cycle. It clears out the crumbs and prevents odors from building up. It keeps the interior smelling fresh and clean between big loads.
Finally, keep the door slightly cracked when the machine is not in use. This allows air to circulate inside. Moisture trapped in the tub is the main cause of mildew. If you have a small kitchen, just open it an inch. It does not need to be wide open. This simple step keeps the interior dry.
- Clean the filter at least monthly.
- Wipe the door gasket with vinegar.
- Run empty cycles with baking soda.
- Avoid leaving dirty dishes for days.
- Use a rinse cycle for partial loads.
- Crack the door to allow airflow.
Getting the Best Results From Your Detergent
The type of detergent you use matters. I prefer tabs or pods for LG machines. They are measured perfectly for a standard load. Liquid detergent can be messy, and powder can leave a gritty film if you use too much. If you have very hard water, look for a detergent that includes a booster. It helps the soap perform better.
Do not overfill the dispenser. The door needs to pop open easily during the cycle. If you cram too much soap in, the door stays shut. The soap will not release until the very end of the cycle. That means your dishes are just getting rinsed with hot water. That is not enough to clean off grease.
Always use a rinse aid. I know, it is another thing to buy, but it is worth it. It breaks the surface tension of the water. This prevents water spots from forming on your glasses. It also helps the dishes dry much faster. Most LG machines have a light that turns on when the rinse aid is low. Keep it full.
If you have a lot of plastic in your load, keep the heat setting low. High heat can bake the detergent residue onto the plastic. It makes them look foggy over time. If you notice a white film on your plates, you might be using too much soap or your water is too hard. Adjust your dose accordingly.
- Use high-quality tabs or pods.
- Do not overstuff the detergent door.
- Keep the rinse aid reservoir full.
- Adjust soap based on water hardness.
- Avoid excessive heat for plastic items.
- Check the manual for detergent recommendations.
Final Thoughts
I hope this guide helps you feel more confident in your kitchen. LG machines are truly excellent once you get the rhythm down. Take a moment to learn where those hidden controls live and you will never struggle again. If your machine acts up, just remember to check the simple things like the door latch or the power supply first. You have got this, and your clean dishes are just a few button presses away.

Frequently Asked Questions
Is My LG Dishwasher Supposed to Be This Quiet?
Yes, most modern LG models are designed to run very quietly. Sometimes they are so quiet you might think they stopped working entirely. Check the display or the indicator light to see if the cycle is still active.
Can I Add More Dishes After the Cycle Starts?
You can open the door carefully during the cycle to add a forgotten item. The machine will pause automatically when the door is opened. Just be careful of the hot steam and make sure to latch it firmly to resume.
Are Dishwasher Pods Bad for My Machine?
Pods are generally safe if you use the right amount for your load size. Do not force a large pod into a small dispenser, as this can break the latch. Always follow the manufacturer’s dosage guidelines for the best results.
Do I Need to Pre-rinse My Plates?
You do not need to pre-rinse, but you should scrape off large chunks of food. Modern detergents need a little bit of residue to work properly, but large bones or seeds can clog your filter and cause issues.
Does the Dishwasher Need Special Salt?
Only if you have a water softening system built into your specific LG model. If your machine does not have a salt reservoir, do not add salt. Check your owner’s manual to confirm if your specific unit requires it.
Should I Use the High Heat Setting Every Time?
You do not need high heat for every load. Use it for greasy pans or sanitizing baby bottles. For daily glasses and plates, the normal setting is plenty and will save you money on your energy bill.
Will the Machine Start If the Door is Not Latched?
No, the safety sensors will prevent the cycle from starting if the door is not fully latched. This is a safety feature to prevent water from spraying out. If you hear nothing, try pushing the door until you hear a click.
How Do I Reset the Control Panel?
If the screen is frozen, unplug the dishwasher from the wall outlet or flip the circuit breaker off for five minutes. This clears the internal computer and usually fixes minor button or sensor errors.
