On the covered Kenmore 722 series dishwasher, AE or E1 means Kenmore's service table lists this code as: water leak detected. Unplug the dishwasher, shut off the water and check the cabinet base for water. Find the source, repair it, then remove the water from the cabinet base.
Differential
Likely causes of “Kenmore 722 series dishwasher code AE or E1”, and how to tell them apart
- 1
Water has leaked into the base of the cabinet and tripped the flood switch
What separates it AE or E1 appears and the base pan is wet
How to confirm Unplug the dishwasher, shut off the water and check the cabinet base for water
- 2
A leak from the fill line, inlet guide, drain pump, drain hose, door seals or sump
What separates it Water drips from one of those parts during a cycle
How to confirm Find the source, repair it, then remove the water from the cabinet base
- 3
A flood switch that has tripped with a dry base
What separates it The base is dry but the switch measures near 0 ohms
How to confirm Disconnect the flood switch wires and measure it; it should read infinite when dry
- 4
Damaged flood switch wires shorting together
What separates it The switch is fine but the wires that go to the board read near 0 ohms
How to confirm Check the sky blue and yellow wires on NA8
- 5
High circulation pump speed from a low water level
What separates it The base is dry and the switch and wires read infinite
How to confirm Check the drain hose configuration, because water can siphon out if the hose is not installed properly
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether there is water in the cabinet base
- Where the leaked water comes from
- The flood switch resistance with the base dry
- How the drain hose is installed

ReversibleAbnormally 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 E1 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.

Unplug the dishwasher, shut off the water and check the cabinet base for water
ReversibleIf water leaked into the base, find the cause: fill line, inlet guide, drain pump, drain hose, door seals or sump. Repair it and remove the water.
If the base is dry, disconnect the flood switch wires and measure the switch
ReversibleIt should measure infinite resistance when the base is dry. Near 0 ohms means the switch tripped dry, so replace the flood switch.
Check the wires to the board, then the drain hose
ReversibleMeasure the sky blue and yellow wires on NA8; near 0 ohms means find and repair the shorted wires. If both read infinite, the code came from a low water level, so check the drain hose installation.
Model-specific
What is true of this model and not of its siblings
- Shown as
- AE or E1 (722 series table).
- Part named by the chart
- Flood switch.
Stop boundary
When this stops being a self-service repair
- !Stop and shut off the water supply before you look for the leak
- !Do not run the dishwasher again until the cabinet base is dry and the leak is fixed
