LG Dishwasher BE Code? (here’s what & what to do)
If your LG dishwasher is displaying the BE error code you might be worrying that your dishwasher is going to need a costly repair. However, there’s no need to worry because in most cases, this error code has an easy to fix solution.
In this article we take a close look at the LG dishwasher BE error code and explain what it means, what causes it and more importantly, how to fix it.
What Does The BE Error Code Mean On A LG DIshwasher?
On LG dishwashers the BE error code stands for Bubble Error and is typically displayed if too many soap suds are detected in areas of the appliance that they are not usually found.
You can help prevent this code from being displayed by; not overloading the dishwasher, using the correct detergent in the correct amount and fixing any mechanical issues.
What Causes The BE Error Code On LG Dishwashers?
The BE error code is fairly common on LG dishwashers that usually is displayed when soap suds or water is detected in areas where they shouldn’t be. This could potentially damage the appliance and needs addressing as soon as possible.
There are a number of reasons which could cause this error code to be displayed which include;
| Probable Cause | Solution |
|---|---|
| Using the wrong detergent | Always ensure you only use specially formulated dishwasher detergent |
| Unlevel dishwasher | Level the dishwasher |
| Software error | Reset the dishwasher |
| Blocked drain hose | Clear any blockage from the drain hose |
| Clogged filter | Clean the filter |
| Defective water inlet valve | Replace the water inlet valve |
| Low water pressure | Improve the water pressure |
| Faulty float switch | Free the float switch if it’s stuck or replace if necessary |
Using The Wrong Detergent
If you use the wrong type of detergent, it could create excess soap suds which could overflow into areas not designed to get water or soap suds.
This would trigger the BE error code. You should only ever use detergents specifically designed and formulated for use in dishwashers. Using washing up liquid is not advisable as this is likely to create too many soap suds and cause the dishwasher to display the BE error code.
If you have used an incorrect detergent and created too many suds, an easy way to clear them is to place a shallow bowl on the top rack filled with 10 ounces (300 ml) of milk. Then run a short wash cycle, the fat in the milk gives the soap suds something to bind with.
This will clear all of the soap suds and leave your dishwasher clean and ready for use again.
Unlevel Dishwasher
If the dishwasher is not level, water and soap suds could flow to areas they’re not designed to enter. This could cause damage to the dishwasher.
This is an easy one to solve, all you need is a spirit level. Check the level back to front and side to side and adjust the feet accordingly. Accessing the front feet entails removing the front kick plate.
You will then be able to adjust the feet using a wrench until the spirit level is perfectly level.
Software Error
In some cases, the BE error code might be displayed on the LG dishwasher due to an electrical glitch or software error. This is another fairly common occurrence and often the cause is unknown.
If you’ve checked the detergent and level of the appliance, you should assume it’s a software error and simply reset the dishwasher. This can be done by disconnecting the power supply for 10 to 15 minutes.
Once the power has been reinstated, the error code should have gone and the dishwasher should be ready to use again.
Blocked Drain Hose
This is another common reason for LG dishwashers displaying the BE error code. All of the water and soap suds are removed from the dishwasher via the drain hose. If the drain hose is blocked or partially blocked it can cause water to back up in the tub triggering the BE error code.
You should inspect the drain hose for any kinks or twists in the pipe, straighten any that you find. Then check that the hose isn’t blocked and if it is you can disconnect one end and run a plumber’s snake through to remove any blockage.
Clogged Filter
The filter on a dishwasher traps all food particles and other debris to prevent it from returning to the now clean dishes. If the filter becomes blocked or clogged, it can prevent water from flowing freely through the drain hose.
This could lead to water backing up in the tub, triggering the BE error code. You need to clean the filter regularly (at least once per month) to prevent this from becoming a problem.
Defective Water Inlet Valve
All of the water that enters the dishwasher does so via the water inlet valve. If this becomes defective, it could impede the flow of water into the appliance which could mean soap suds don’t get removed correctly.
You can inspect the inlet valve manually for any sign of leaks etc. If it does need to be replaced, we recommend getting a technician to do this for you.
Low Water Pressure
If there is insufficient water entering the dishwasher, it is possible that the BE error code could be displayed. This could be caused by a twisted inlet hose, blocked inlet filter, or the water entering your home has insufficient pressure.
Check the inlet hose for twists or kinks, check the inlet filter for any blockages and check the water pressure. You can do this by filling a 1 gallon (4.5 litre) bucket with water from the cold tap in your kitchen.
If it takes 30 seconds or less to fill, the water pressure is fine, if it takes longer than 30 seconds, you will need to contact your water authority.
Faulty Float Switch
A dishwasher’s float switch monitors the water level in the tub. If it becomes stuck it can cause the BE error code to display. You can check the float switch yourself by removing the bottom panel on the dishwasher.
Once you’ve located the float switch gently lift it free from its position. Then replace the panel and run a short cycle to check if the error code has cleared. If the float switch keeps sticking, it will need to be replaced.
Ways To Prevent Error Code BE From Showing On An LG Dishwasher
Once you’ve successfully cleared the BE error code from your LG dishwasher, you should always do the following to prevent it from happening again.
- Have A Regular Cleaning Schedule
You should run a hot service wash cycle at least once per month to ensure the proper running of your dishwasher. This should include cleaning the filter once per month as well as wiping the door seal (gasket) to remove any food scraps or mould spores. - Scrape Dishes Before Loading
By removing all of the larger food particles from your dishes before placing them in the dishwasher, you will minimise the chance of any blockages. - Use The Correct Type & Amount Of Detergent
You should only ever use detergent specifically designed for use in a dishwasher. You should also ensure to not use more detergent than is recommended. - Check The Hoses & Water Supply
It is a good idea to check that none of the hoses on the dishwasher are twisted or kinked at least once a month. - Never Overload The Dishwasher
If you place more dishes in the dishwasher than it was designed to hold, this could cause problems which include the appliance displaying the BE error code.
