How to Clear AE Code on LG Dishwasher (Fast Fixes)

It’s such a headache when your LG dishwasher stops mid-cycle, flashes an AE code, and leaves a puddle on the kitchen floor. You might feel worried, but this code usually means there is a water leak at the bottom of the machine. Most of the time, a simple sensor trip causes the alarm. You can often fix this issue at home, save your floor, and get your dishes clean again, starting with these easy, proven steps.

You should first unplug the dishwasher or turn off the power at the breaker box, so you stay safe. Pull the machine away from the wall, then check for any visible water leaks underneath the unit. You need to tilt the dishwasher carefully to let any pooled water drain out from the base tray. Once the sensor stays dry, the AE error code should vanish, letting you finish your wash cycle just like normal.

What Does the AE Code Actually Mean?

An AE error code shows up on your LG dishwasher when the internal float switch senses water in the base, or the drip pan, of the machine. This is a safety feature, designed to stop your kitchen floor from flooding, so try not to panic. Here is what you need to know about why this happens, how it works, and what it means for you.

Sensor Function

The main sensor sits at the very bottom of the dishwasher, tucked away near the base. When water touches this spot, the machine stops running, turns on the drain pump, and shows the AE code. This stops the unit from leaking more water onto your floor, which helps you avoid big water damage.

Leak Source

Water inside the base tray usually comes from a loose hose, a bad seal, or a crack in the pump area. Sometimes, a tiny amount of water escapes during a cycle, collects in the pan, and triggers the alert. You must find the leak source, or the code will surely return soon.

Faulty Switch

Sometimes the sensor switch breaks, gets stuck, or just acts weird after a long time. Even when the tray is totally dry, a bad switch keeps sending an error signal to the screen. You might need to check the wires, or replace the part, if the tray stays dry but errors persist.

Foam Build-up

Excess soap suds can leak out of the door seal, drip down into the pan, and trip the sensor. This often happens if you use too much soap, or the wrong kind, during a normal wash. Keep your soap use low, watch for suds, and your sensor will likely stay happy.

Door Seal

The rubber gasket around your door keeps water inside, but it can wear out or get dirty over time. A gap in the seal lets water spray out, hit the floor, and eventually pool in the base. Wipe the seal clean, check for tears, and replace it if it looks brittle.

Drain Hose

The hose carrying dirty water away can crack, clog, or shake loose from the pump connection. If water drips from this hose, it will hit the bottom pan, and your machine will show the AE code. Check all your hose clamps, make sure they are tight, and look for any small wet spots.

Finding a leak takes patience, but you can do this by checking each part carefully. Start with the easiest areas first, like the door gasket and the visible hoses. If the leaks stop, your machine will run smooth again.

• Check the door seal for gaps.
• Look for loose hose clamps.
• Wipe up all standing water.
• Use less soap next time.
• Check the drain pump area.
• Tilt the unit to drain.

How to Clear AE Code on LG Dishwasher

Clearing the AE code involves finding the leak, drying the sensor, and resetting the system so it works well again. You do not need fancy tools, just some towels and a bit of time to look things over. Follow these steps carefully, stay calm, and you will get your dishwasher back in shape without needing to call a professional repair person for help.

Power Off the Unit

First, go to your breaker box and flip the switch to turn off power to the dishwasher. This keeps you safe while you work, especially near water. Once the power is off, you can pull the dishwasher out from under the counter to see the back and the bottom tray area.

Always keep your feet dry, and wear shoes, because water can be slippery. Do not touch any wires or the plug if your hands are wet. Safety comes first, so make sure the machine is completely dead before you start looking for the source of the water leak.

Take your time moving the machine, because it might be heavy, and you do not want to scrape your floor. Once it is pulled out, grab a flashlight to help you see into the dark corners. You are now ready to inspect the base for any water.

Drain the Base Tray

Next, you need to tilt the dishwasher gently to the back to let the water inside the base pan run out. Lay some old towels down on the floor first, so you do not make a bigger mess than you already have. This step is very important because the sensor stays wet until the water leaves.

As you tilt the machine, you might hear water sloshing, which means you found the problem area. Hold it at a slight angle for a few seconds, until the water stops dripping onto your towels. This removes the water from the tray, which usually clears the error once the machine powers up.

If you cannot tilt the unit, use a shop vac or a small sponge to soak up the water from the base. Be very thorough, because even a small amount of moisture can keep the sensor active. Keep drying until the tray is bone dry and clean to the touch.

Inspect the Door Gasket

Now that the base is dry, check the rubber seal all the way around your dishwasher door. Look for food bits, hard soap buildup, or small tears in the rubber that might let water leak out. If you see dirt, wipe it away with a damp cloth and some mild dish soap.

A loose or dirty seal is a very common reason for water to reach the base tray. If the seal looks stiff, old, or damaged, you should look into buying a new one. Replacing the gasket is a quick job, and it prevents water from spraying out while the cycle runs.

Make sure the seal sits flush against the metal door frame, with no gaps or loose spots anywhere. If the door closes tight, you will not have leaks from the front side. This simple check often solves the mystery of why water reached the sensor tray in the first place.

Check the Drain Hose

Look at the drain hose at the back of the dishwasher to make sure it is not cracked or leaking. Check the clamp where the hose connects to the pump, because vibrations can make it wiggle loose over time. If the hose feels soft, mushy, or looks cracked, it definitely needs a quick replacement.

Sometimes the hose gets kinked, which makes water back up and leak out of the pump area. Straighten out any bends, and ensure the hose has a clear path to your sink drain or your garbage disposal unit. A clear hose flows better, prevents backups, and keeps your base tray nice and dry.

Check the connection point at the sink or disposal too, as leaks can happen there and run back down the hose. A tight, secure connection keeps your system leak-free. If you find a leak, tighten the clamp or replace the hose to stop the water from dripping down again.

Test the Float Switch

If the base is dry but the error remains, the float switch itself might be stuck in the up position. Find the small plastic sensor at the bottom, and try to move it up and down with your finger. It should click and move freely, without getting stuck on any dirt or debris.

If the switch feels gritty, try to clean it gently with a soft brush or a bit of vinegar. Sometimes old soap residue makes the plastic part sticky, which prevents it from dropping back down. Once the switch moves smoothly, it should stop sending the error signal to your display panel.

If the switch is broken or does not click, you might need to buy a new one to fix the code. This part is usually easy to swap out with just a screwdriver. A fresh switch will reliably detect water and keep your machine running safely for many years to come.

Reset the System

Finally, turn the power back on at the breaker box, and see if the AE error code has cleared. Often, the machine needs a few seconds to boot up and recognize that the sensor is now dry. If the screen looks normal, try running a quick rinse cycle to be sure.

Watch the dishwasher closely during the first cycle to make sure no new water leaks appear on the floor. If the cycle finishes without the code, you successfully fixed the problem. You can then push the dishwasher back into its spot under the counter and finish your day.

If the code comes back, re-check the base tray for any new water, as you might have a hidden leak. Sometimes it takes two tries to catch everything. Stay patient, keep checking the hoses, and you will get it working right again soon.

After you clear the code, keep an eye on your floor for a few days. If the area stays dry, you likely fixed the problem for good. Just remember to check your hoses and seals once every few months to stay ahead of any potential future leaks.

• Clear the base tray completely.
• Replace damaged rubber door gaskets.
• Tighten all loose hose clamps.
• Clean soap off the sensor.
• Ensure the drain hose flows.
• Test with a short cycle.

Is the Dishwasher Leaking From the Bottom?

Water on the floor is the classic sign of a leak, but you need to be sure where it comes from. Sometimes water drips from the door, rolls down the front, and settles right under the machine. Other times, the leak starts deep inside the pump area. You have to peek underneath to know for sure.

Check the front of your dishwasher first, because the door seal is the most common place for leaks to start. If you see water trails on the door, your seal is probably the culprit. You can replace this part easily, and it stops the mess from reaching your floor and your sensor.

Next, look under the unit with a bright light to see if the leak is happening while it sits idle. If you see water dripping from the pump, you might have a loose hose or a bad pump seal. These internal leaks are more annoying to reach, but they are still fixable with some time.

Finally, consider the drain hose that leads to your sink, as it could be leaking at the connection point. If the drain is blocked, water can push out of the connection and run down the hose to the floor. Keeping your drain clear prevents this kind of pressure-based leak from ever happening.

• Look for water trails on the door.
• Check the floor near the kickplate.
• Use a flashlight under the machine.
• Feel the hoses for wet spots.
• Listen for dripping sounds inside.
• Inspect your sink drain connections.

Should I Call a Professional Repair Person?

Calling for help is a smart choice if you feel overwhelmed, or if the leak seems to come from deep inside the pump. Dishwashers have lots of parts, and sometimes it is just better to let a pro handle the hard stuff. There is no shame in asking for help when things get too complicated for you.

You should consider a repair pro if you fixed the leak but the AE code stays on the screen forever. This might mean the main board is hurt, or the wiring has a short, which is hard to fix on your own. A pro has the tools to test these parts, saving you from guessing what to do.

Think about how much time you want to spend on this, because taking a dishwasher apart takes a while. If your weekend is busy, paying someone to handle the repair gives you your time back. Plus, they can often find hidden issues you might miss, like a failing pump that is about to quit.

Keep in mind that some parts are very cheap, but labor costs add up fast, so get an estimate first. Ask the repair person to explain exactly what they see, so you learn how to avoid the same problem later. Always choose someone with good reviews to make sure the job gets done right.

• Call if the code persists.
• Ask for an estimate first.
• Check for local repair reviews.
• Look for warranty coverage options.
• Ask about recurring leak causes.
• Compare prices for new parts.

Can Soap Cause the AE Error Code?

Soap is meant to clean your dishes, but it can cause big problems if you use too much of it. Excess suds create pressure inside the tub, which forces water out of places it should not be. This soapy water eventually drips into the base tray, trips your sensor, and gives you that annoying AE error code.

You should always use the amount of detergent listed on the bottle, or even a bit less, to keep suds down. Most modern dishwashers use very little water, so they really do not need much soap to do a great job. Using less soap keeps your machine cleaner, and it prevents those messy foam leaks.

If you accidentally use too much soap, you might need to run a few rinse cycles to clear the suds out. This is annoying, but it is much better than having water leak all over your kitchen floor. Just be patient, wipe up any suds you see, and keep the cycles running until the foam disappears.

Switching to a high-quality detergent made for dishwashers also helps, because it creates fewer bubbles. Cheap soap often bubbles way too much, which leads to these kinds of leaks. Spend a little extra on good soap, and your machine will run much smoother in the long run, with fewer errors popping up.

• Use less soap than expected.
• Only use dishwasher-safe detergent.
• Avoid adding liquid dish soap.
• Run rinses if suds appear.
• Clean the door seal often.
• Check for foam under the unit.

Is the Drain Hose Kinked or Blocked?

Your drain hose is the lifeline for all that dirty water, so it must stay clear for the machine to work. If the hose gets bent, crushed, or filled with food scraps, the water has nowhere to go. It backs up, finds a weak spot, and leaks out into the base tray, which triggers the AE alarm.

Check behind your dishwasher to see if the hose got smashed when you pushed the unit back into place. A tight squeeze can kink the hose, slowing down the flow and causing pressure to build up inside the pump. Move the dishwasher carefully, and make sure the hose has plenty of room to breathe.

If the hose is clear, check the end that goes into your sink drain or your garbage disposal. Often, food scraps get stuck right where the hose meets the sink, creating a nasty clog. Use a small brush to clean that area, and make sure the connection point is secure and tight.

Consider replacing the hose if it looks old, brittle, or cracked, as even a tiny hole causes a leak. A new hose is cheap, easy to install, and gives you peace of mind. Keeping the path clear prevents water backups, which is the best way to avoid the AE error code for good.

• Check for bends behind the unit.
• Look for clogs at the sink.
• Inspect the hose for cracks.
• Make sure the clamp holds.
• Clear out any trapped food.
• Replace if the hose feels soft.

Final Thoughts

I hope this guide helps you clear the AE code on your LG dishwasher quickly. It is frustrating when chores pile up, but you have the power to fix this leak yourself. Just take it slow, keep your floor dry, and check those simple parts first. Most of the time, a little cleaning and a quick dry do the trick. You can get back to your day, and your clean dishes, in no time at all.

Frequently Asked Questions

Is the AE Code Dangerous to My Home?

The AE code itself is a safety alert, not a danger, because it stops the machine to prevent floods. However, if you ignore the leak, water can damage your floor and cause mold. Fix the leak fast.

Can I Reset the Dishwasher by Unplugging It?

Yes, unplugging the unit is a great way to try a hard reset after you dry the tray. Leave it unplugged for ten minutes, plug it back in, and see if the code stays away.

Are There Other Codes Like AE?

Yes, LG dishwashers use many codes for different problems, like OE for drain issues or LE for motor trouble. Each code points to a specific spot, so check your manual for the right fix.

Do I Need Special Tools for This?

You mostly need a screwdriver, some old towels, and a flashlight to see well. If you need to swap a hose or a sensor, a pair of pliers might help, but nothing fancy is required.

Should I Use Vinegar to Clean the Sensor?

Vinegar is fine for cleaning soap scum off the sensor, but use it sparingly and wipe it dry. Do not soak the electrical parts, as moisture there can cause more errors later on today.

Will a Bad Pump Cause the AE Code?

Yes, a leaking pump seal is a common source of water in the base tray. If you keep finding water even after fixing the hoses, the pump might need a closer look or replacement.

Can I Run the Dishwasher with a Small Leak?

No, never run the dishwasher if you know it is leaking, as the water will collect and trigger the sensor again. Fix the leak first, or you will just end up with more puddles.

Does an LG Dishwasher Have a Warranty?
