AE & E1 ERROR CODE - DISH WASHER

  • Troubleshooting
LG - Dishwasher E1 or AE Error Code

The AE or E1 error code indicates a possible leak from the unit. This message is usually the result of an overflow, caused by either the unit not being level or the wrong type or amount of detergent.

  1. What type of detergent do you use?


  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 24-48 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. If the error code occurs again, service will be required.

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

  3. To start, we are going to check the unit's leveling.

    • Open the dishwasher. Place a leveler inside the dishwasher against the ceiling.
    • open the dishwasher
    • With the unit still open, place a level vertically on the front side of the cabinet.
    • place level vertically
    • Lift the lid like you're going to close it, but leave it cracked a few inches. Make sure that the gap between the door and the tub is equal on both the left and right sides.
    • lift lid
    • Next, we will check to see if the floor of the unit is correctly leveled. Please run a normal cycle on your unit. After the initial water fill (this shouldn't take long) check to see if the water is pooling to one side or the other, or if it is around the center. If the water level is off to either side of the tub the unit may not be correctly leveled. Note: If the diswasher is not leveled correctly, it may leak during operation.

    NOTE: If the unit is leveled and the proper amount of detergent is used, and the error code continues to display, service may be required. Please visit our Request a Repair page.

  4. Liquid or Powder Dishwasher Detergent

    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 24-48 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. If the error code occurs again, service will be required.

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

  5. Using dishwashing liquid , 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, 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.

    • If the base is not visible or accessible from the front, leave the kickplate off for 24-48 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.

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