    Hi,
    A copy:

    E1

    Condition: Water leak detected

    Check/Repair: Abnormally high circulation pump speed caused by low water level in the tub can cause the AE or E1 error codes. Water that leaks into the base of the dishwasher cabinet and trips the flood switch can also cause the AE or EI code. Unplug the dishwasher and shut off the water supply. Check the dishwasher cabinet base for water. If water leaked into the base, find and repair the cause of the leak. Water could leak from the water fill line, water inlet guide, drain pump, drain hose, door seals or sump. After repairing the leak, remove water from the cabinet base. If the code appears and no water leaked into the cabinet base, disconnect the flood switch wires and check the resistance through the flood switch using a multimeter. The meter should measure infinite resistance when the cabinet base is dry. If the meter measures near 0 ohms, replace the flood switch because the switch tripped with the cabinet base dry. If the meter measures infinite resistance, reconnect the flood switch wires and check resistance through the flood switch wires that connect to the electronic control board (sky blue and yellow wires on NA8). The meter should read the same resistance as for the flood switch. If the meter measures near 0 ohms, find and repair the damaged flood switch wires that are shorting together. If the meter measures infinite resistance, then the AE or E1 code was likely caused by high circulation pump speed due to low water level. Check the configuration of the drain hose because water can siphon out of the dishwasher if the drain hose isn’t installed properly. Follow the directions in the installation guide to properly install the drain hose.
