AE & E1 ERROR CODE - DISH WASHER

Troubleshooting Dishwashers Last Updated 12/13/2017
LG - Dishwasher E1 or AE Error Code

The AE or E1 error code indicates a possible leak from the unit. This is most often caused by excessive suds overflowing into the base of the dishwasher. Let’s check if this is the case.

  1. What type of detergent is used?


  2. Generally, pods or tablets contain the correct amount of detergent, however, if more than one pod or tablet is used OR the water is soft the amount may actually be too much.

    This will cause excessive suds and water to overflow into the base. There is a float switch in the base that will detect this overflow and display the AE / E1 error code.

    To check if water is in the base, TURN OFF THE BREAKER and then you can easily remove the kickplate and check in the bottom middle of the dishwasher to see if the base is accessible. If yes, use a paper towel or hand towel to soak up the water.

    1. Base behind kickplate.

    2. Inspect middle of base.

    • If there is no water in the base, it may have already evaporated.

    • If the base is not visible or accessible from the front, leave the kickplate off for 24 hours to improve evaporation.

    • Once the water is soaked up or enough time has passed for the water to evaporate, turn off the circuit breaker and turn it back on to reset the dishwasher. Then run an empty cycle with nothing in it to clean out the dishwasher.

    How to reset AE error code (reset the dishwasher):

    • Turn off the circuit breaker for at least 60 seconds.

    • Turn the circuit breaker back ON.

    • Turn the unit back ON and check if the error code is removed. If not try turning the circuit breaker for a longer period untill the error is cleared.

    NOTE: If the proper type and amount of detergent is used, but the error code continues to display, the unit will require a repair service. Please visit our Request a Repair page.

  3. How much detergent is used?

    The dispenser has two marked levels for dishwasher detergent. If filling up the entire dispenser, this will cause excessive suds and water to overflow into the base.

    There is a float switch in the base that will detect this overflow and display the AE / E1 error code. Determine if too much detergent is used:

    • 15 Line: Soft water conditions or lightly soiled loads.

    • 25 Line: Hard water conditions or heavily soiled loads.

    • Between 15 and 25: Average or medium water conditions and soil level.

    15 25 level

    To check if water is in the base, TURN OFF THE BREAKER and then you can easily remove the kickplate and check in the bottom middle of the dishwasher to see if the base is accessible. If yes, use a paper towel or hand towel to soak up the water.

    1. Base behind kickplate.

    2. Inspect middle of base.

    • If too much detergent is used, but there is no water in the base, it may have already evaporated.

    • If the base is not visible or accessible from the front, leave the kickplate off for 24 hours to improve evaporation.

    • Once the water is soaked up or enough time has passed for the water to evaporate, turn off the circuit breaker and turn it back on to reset the dishwasher. Then run an empty cycle with nothing in it to clean out the dishwasher.

    How to reset AE error code (reset the dishwasher):

    • Turn off the circuit breaker for at least 60 seconds.

    • Turn the circuit breaker back ON.

    • Turn the unit back ON and check if the error code is removed. If not try turning the circuit breaker for a longer period untill the error is cleared.

    NOTE: If the proper type and amount of detergent is used, but the error code continues to display, the unit will require a repair service. Please visit our Request a Repair page.

  4. Using liquid dish soap (hand dish-washing soap), INSTEAD of dishwasher detergent, will result in excessive suds and water to overflow into the base. There is a float switch in the base that will detect this overflow and display the AE / E1 error code. In this case, a repair service is NOT NECESSARY.

    To check if water is in the base, TURN OFF THE BREAKER and then you can easily remove the kickplate and check in the bottom middle of the dishwasher to see if the base is accessible. If yes, use a paper towel or hand towel to soak up the water.

    1. Base behind kickplate.

    2. Inspect middle of base.

    • If there is no water in the base, it may have already evaporated.

    • Once the water is soaked up or enough time has passed for the water to evaporate, turn off the circuit breaker and turn it back on to reset the dishwasher. Then run an empty cycle with nothing in it to clean out the dishwasher.
