Your LG vacuum is not working. Do not fret about it. I can help you fix it fast. It is a real pain when gear breaks down. I know this from my own life. You just want a clean floor.
I test and fix gear all the time. It is what I do for my site. I find out why tools fail. I took my LG vac apart last week. I looked at all the small parts. I want to share my top tips with you today.
Most times, you do not need a pro. You can do the work right at home. You just need your hands and some time. I will walk you through each step. We will get your vac back to full health.
Quick Data on Common Vacuum Faults
I like to look at the facts first. Data points us to the right fix. Here is a chart of the top flaws. It shows what goes wrong the most. It also gives the best quick home fix.
| Bad Sign | The Root Cause | The Easy Home Fix |
| Dies fast | Blocked air path | Wash all the foam parts |
| No power | Dirty metal pins | Wipe the charge dots |
| Brush stuck | Pet hair jam | Cut hair off with shears |
| Weak pull | Full dirt bin | Dump the dust right out |
The Vac Shuts Off Very Fast
This is the most common flaw I see. You press the on switch. The vac starts to hum. But the sound goes up and down. Then the vac just dies out flat.
You might think the whole thing is dead. Do not throw it out just yet. This fast shut off is built in. It is a fail safe for the main parts. It keeps the core safe from heat.
Why the Main Motor Stops
Your vac has a smart chip inside. This chip feels how fast the air moves. If the air stops, heat builds up fast. Too much heat will melt the core motor.
The chip kills the power to stop a fire. It is a good trait to have. But it means you have a big clog. The air can not flow through the main tube. We must clear that path right now.
How to Wash the Dirt Filters
The top cause of no air is dirt. Dust coats the main foam pad. It gets as thick as a wool coat. You must wash this foam off. Pop the top lid off the vac head.
Pull out the round green or yellow foam. It will look gray and gross. Hold it under warm tap water. Squeeze it a few times in your hands. Watch all the black mud wash down the sink.
Do this until the water runs clear. Shake the wet foam out well. You also need to clean the back mesh part. Tap it on the side of a trash can. All the loose dust will fall right out.
Let the Wet Parts Dry
Now you must wait a bit. You can not use wet parts at all. If you put a wet pad back in, you will ruin the vac. Water will get sucked right into the motor base.
Put the clean foam on a dry rag. Leave it in a bright sun spot. Let it rest there for a full day and night. Make sure it is bone dry to the touch. Then you can put it all back.
The Machine Has Zero Power
Some days the vac has no signs of life. No lights blink. No sounds play. It just sits there like a dead log. This means the power loop is broken. The juice can not flow.
I see this a lot in my test shop. Folks think the battery is shot. But that is often not the case at all. The fix is much less work than you think. Let us check the links.
Check the Cell Pack Fit
First, look at the base cell pack. Did it click all the way in? Push it hard with your thumb. You should hear a sharp snap sound. If it is loose, power will not flow.
Sometimes a bump will knock it loose. Just give it a firm shove. If it is snug, take it out of the base. We need to look at the metal parts next. This is where the root flaw lies.
Clean the Dust off the Pins
Look at the stand where the vac rests. You will see small metal prongs stick up. These touch the vac to charge it up. Over time, house dust coats these small parts.
Dust is bad for power flow. It stops the juice cold. Take a dry, clean cloth. Rub the metal prongs hard. Wipe away all the gray film. Make them shine like new.
Do the exact same thing to the vac base. Wipe the small slots clean. Set the vac back on the base stand. See if the charge lights wake up. If they do, you fixed the dead loop.
Test Your Home Wall Plug
We can not forget the wall plug. It might be dead on its own. The house fuse might be tripped. You need to rule this out first. It is a quick test to run.
Grab a small desk lamp. Plug it into the exact same wall slot. Flip the lamp switch on. If the bulb stays dark, your house is the fault. Your LG vac is just fine.
The Floor Brush Will Not Spin
You turn the vac on and it hums nice. But you look down at the rug. The main floor brush is still. It does not turn at all. This means it will not pick up dirt.
It will just push the mess left and right. This is a big let down. Carpets need a fast brush to get clean. If the brush is dead, the whole tool feels useless to you.
Look for a Bad Hair Jam
I know why this happens right away. It is almost always a hair jam. We lose hair all the time. Dogs and cats shed fur all day long. The vac eats it all up.
Long strands wrap tight round the brush bar. They spin and pull tight like a thick rope. They jam the side wheel gears. The hair acts like a strong brake. It chokes the small floor motor.
How to Cut the Hair Free
Flip the floor head on its back. Look near the side walls. You will see a huge knot of hair and string. You need a flat coin to fix this part. Put the coin in the side lock slot.
Turn the lock to the left. The side cap will pop right off. Pull the whole round brush out of the shell. Take a sharp pair of shears from your desk. Cut a long line down the thick hair knot.
Pull all the gross chunks free. Toss them deep in the trash bin. Wipe the bare round ends with a dry cloth. Slide the clean brush back into the floor head. Lock it tight with your coin.
Check the Floor Head Prongs
The floor base has its own small motor. Power goes down the long metal pipe to run it. Take the long pipe off the main vac base. Look at the end of the pipe.
You will see two small metal tips. These tips pass the power down. Make sure they are straight and clean. If they bend back, they can not touch. Then the floor brush gets no juice to run.
The Vac Has Very Weak Suction
Your vac might turn on and spin fine. But it leaves crumbs in its wake. It feels weak and sad. You have to roll over the same spot five times. This wastes your time and your hard work.
Weak pull means the air path is choked. Air must flow fast to grab dirt. If a wall is in the way, the air slows down a lot. We need to find that wall and smash it.
Dump the Full Dirt Cup
Look at the clear front dirt cup. Is it filled past the top max line? If the cup is packed tight, the air can not swirl. The dirt blocks the cyclone spin action flat out.
Take the whole vac to your outside trash bin. Click the bottom door catch. Let the heavy chunk of dirt fall out. Shake it a bit to clear the top rim. This gives the air room to breathe and spin.
Clean the Fine Mesh Tower
Just dumping the loose dirt is not enough. Look deep up inside the clear cup. You will see a plastic cone with tiny holes. Dust sticks to this cone like thick gray glue.
Take your long skinny tool end. Put it in the base of the mesh cone. Twist the tool to the left side. Pull the cone straight down to get it out. Take it far from your face.
Tap it hard on the edge of the trash bin. Use an old dry brush to sweep the small holes. Get all the fine dust out of the tiny cracks. This frees up the main air flow big time.
Do the Coin Drop Test
Sometimes a large thing gets jammed deep. A piece of stiff mail or a kid toy can block the main pipe. Take the long metal wand off the vac. Hold it straight up tall in the air.
Drop a heavy coin down the top hole. Keep your ear close and listen well. Did the coin clink on the floor fast? If yes, the pipe is clear of jams. You are good to go.
Did the coin stay stuck in the pipe? If yes, you have a solid mass in there. Get a long wood broom stick. Push it soft down the pipe. Shove the stuck mass out the back end.
How to Make Your LG Vac Last
I have tested scores of tools over time. I see what makes them break down fast. Lack of care is the main killer of gear. You can add years of life to your machine with good care.
It just takes a small chunk of your time. You spent good cash on this tool. You should keep it in tip top shape. A clean tool is a happy tool that works well for you.
Have a Tool Care Day
Pick one specific day each month. Make it your official tool care day. Empty the dirt bin all the way out. Wash all the soft foam parts. Let them dry in the hot sun.
Wipe the charge pins with a clean cloth. Cut the long hair off the base roller. This chore takes ten whole minutes. It stops huge breaks from hitting you later on down the line.
Keep the Unit Safe Inside
Do not leave the vac in a hot car trunk. Do not keep it in a cold out shed in the snow. Huge shifts in heat will kill the power cells fast. The cells like it nice and warm.
Keep the vac stored in your main house rooms. A hall closet is a great spot for it. Room temps keep the battery pack strong for a long time. It will hold more juice per charge this way.
Parts You May Need to Buy Soon
Fixes will not work forever and ever. Parts wear down as the years go by. It is a harsh fact of tool life. You should know what to look out for as time goes on.
Knowing this helps you plan out your cash. You will not get mad when a part fails. You will know it is just the end of its life span. You can swap it out for a fresh part.
A Fresh Power Cell Pack
Battery packs do not last till the end of time. They hold less and less charge each new year. After three full years, the run time will drop off a cliff. The vac will die in ten short minutes.
When this day comes, you need a new pack. They cost a good chunk of change. But they breathe new life right back into the vac. It will feel brand new on your rugs once more.
Clean New Foam Filters
Foam parts also break down with long use. Washing them helps them last a lot longer. But the foam gets thin and weak over time. It can even rip if you squeeze it too hard in the sink.
I tell folks to buy a new foam set once a year. They are quite cheap to get online. They keep the core motor safe from fine grit. Fresh foam means strong pull on your floors.
My Last Words on LG Vacuums
I like the way LG builds their home tools. They make solid machines that look nice. The parts snap in place with a good firm feel. The thick plastic feels quite tough in your hands.
They are not one hundred percent perfect. The dirt cups are a bit too small for big homes. They clog up fast if you own big hairy pets. But they are simple to pull apart on your own.
You do not need a big degree to fix them. I fixed my own dead vac that cold Sunday. It was just a clogged foam pad and some stuck hair. It took me no time at all to solve.
My home floors are spot free once again. I am quite pleased with the end result. I hope this deep guide helps you win the fight. Keep your gear clean. They will serve you well for years.
