Select the error code on your display:
IE Error Code
An IE error code indicates that the level of water in the unit did not get high enough after 10 minutes of filling. To resolve this error, please check the following:
-
Newly Installed units.
If the unit was recently installed, be certain that the water supply valve is turned ON and the water line is not kinked or bent.
-
Water pressure.
Water pressure must be between 20 - 120 PSI. If this is too low, contact a plumber to correct the issue.
-
Drain Hose outlet installation.
If your drain hose outlet is installed lower than the base of your dishwasher, it is possible that this could cause premature draining.
The height of the drain hose end must be over 10 inches (almost 12 inches) from the bottom of the dishwasher to avoid water being siphoned from the tub. In this case, reinstall it according to the instructions in the owner's manual. You can download a copy from our Manuals and Documents
-
Winter weather.
If your dishwasher is installed in a location where parts of it could be exposed to temperatures below freezing, it is possible for parts of the dishwasher to freeze. Melt the frozen parts by soaking a towel in warm water and wrapping it around the frozen area. Once the frozen area has thawed the dishwasher should be able to operate.
-
Improper leveling.
Check the leveling of your dishwasher as improper leveling may cause IE.
-
Flood Safe Hose/Check valve.
Flood Safe hoses and check valves may interrupt the water supply, due to high water pressure passing through the inlet valve. It is recommended to remove such devices in favor of standard inlet hose.
Inspect the water line for kinks or bends that may be prevent proper filling.
If you perform all the above steps and the the IE error code persist, the unit will require a repair service. Please visit our Request a Repair page.
2H - Estimated Time
A 2H is only an indicator of the estimated time remaining for the cycle. 2H means the estimated time remaining is less than 2 HOURS, when the time is less than 99 minutes, is starts counting down untill the washing cycle is over..
This is NOT an error code and does Not require a repair service.
CD Error Code
This is NOT an error code; it indicates that the unit is currently running COOL-DRY. This is an additional drying cycle used in the QUICK cycle.
bE Error Code
bE error code indicates the use of improper detergent or failure to level the appliance. To resolve the issue:
-
What kind of detergent do you use?
Do not use hand-washing liquid detergents. This type of detergent is not intended for automatic dishwashers and will cause excessive sudsing and, possibly, leaks. Poor washing and drying performance will result.
Only use dishwasher detergents such as cascade, finish e.t.c.
-
Is the dishwasher level?
The dishwasher must be leveled properly from front to back and side to side to ensure proper drainage and avoid damage and malfunction. For more instructions, please visit our LG Dishwasher - Leveling page.
-
Are there suds visible in the dishwasher tub?
If suds are visible, pour 4-7 ounces of milk in a shallow bowl, place it on the upper rack, and run the appliance on the AUTO cycle. The fat content in the milk will give the suds something to bond to, allowing it to rinse out properly.
If you always use the right detergent, the dishwasher is level, and there are no suds in the tub, then RESET the power and run a cycle again with proper detergent.
