Kenmore 722 series dishwasher error codes:

Reference Model: Kenmore 722.######## series dishwasher error codes

These error code explanations can help you diagnose a problem with a Kenmore dishwasher that begins with model numbers 722.


Code Meaning Possible Cause Possible Parts
IE Not filling Check that the water supply cut-off valve for the dishwasher is fully open. Check the water inlet supply hose for a kink. Unplug the dishwasher, shut off the water supply and disconnect the inlet supply hose from the inlet water valve. Check the filter screen on the inlet water valve for a clog-replace the valve if the filter screen is clogged. If the inlet screen isn't clogged, place the end of the water inlet supply hose in a container and briefly open the water supply cut-off valve to check water flow through the hose. If water doesn't flow through the hose, repair the water supply failure. If supply hose water flow is good, check the inlet guide assembly for clogs Water inlet valve, electronic control board, See * notes at bottom of the page
OE Not draining Check the sink drain or garbage disposal for a clog and clear any clogs you find. If the sink or garbage disposal drains okay, pull off the dishwasher drain hose from the sink or garbage disposal connection and check the end of the drain hose for a grease clog. Clear grease clogs from the drain hose. If the dishwasher uses an air gap, check the air gap for clogs and clear any clogs. Unplug the dishwasher and check the entire drain hose between the drain pump and the sink drain connection for clogs and clear any drain hose clogs. If you find no clogs in the drain path, check the dishwasher sump and drain pump for clogs and remove any clogs Drain pump, electronic control board, See ** notes at bottom of the page
AE or E1 Water leak detected 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 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 Flood switch
FE Water overflow detected The drain pump automatically runs when the FE code is displayed. A leaking water inlet valve or a stuck relay on the electronic control board can allow water to fill the dishwasher constantly. To check for a leaky water inlet valve, unplug the dishwasher and see if the tub continues to fill with water. If it does, shut off the water supply and replace the water inlet valve because the valve is letting water to flow into the dishwasher constantly. If water stops filling when you unplug the dishwasher, then you'll likely need to replace the electronic control board Water inlet valve, electronic control board
tE Thermistor (temperature sensor) failure Unplug the dishwasher and disconnect the wires from the thermistor on the heater. Measure the resistance through the thermistor using a multimeter. The meter should measure 11,320 ohms at 75 degrees (room temperature). Replace the heater assembly (which includes the thermistor) if the meter measures less than 1,000 ohms or more than 20,000 ohms Heater assembly, electronic control board
LE Locked up circulation pump motor Unplug the dishwasher and check for an obstruction that's preventing the pump impeller from spinning. Remove any debris or foreign objects from the sump. If the pump impeller is clear, check the wiring connections on the pump and reconnect any loose wires. If the wiring connections are okay, unplug the wire harness from the motor and check the resistance through pins 1-2, pins 2-3 and pins 1-3 of the motor using a multimeter. The meter should measure between 8 and 20 ohms (resistance of the motor windings). Check the RPM sensor by measuring resistance through pins 7-4 and 7-5. The meter should measure 8,000 to 10,000 ohms. Replace the circulation motor if any resistance measurement is near 0 ohms or infinite resistance Circulation pump motor, electronic control board
HE Heating failure This code appears when water isn't heating or when the thermistor (temperature sensor) detects that water temperature is higher than 194 degrees. If water inside the dishwasher tub is extremely hot, measure water temperature using an accurate thermometer. If the thermometer measures water temperature near 190 degrees, then you'll likely need to replace the electronic control board because a stuck heater relay on the control board is causing the heating element to stay on constantly Heating element, pressure switch, electronic control board
nE Diverter motor failure Unplug the dishwasher and check the wire harness connections on the diverter motor and diverter position switch. Reconnect any loose wires. If the wiring connections are okay, unplug the diverter motor wires and check resistance through the motor using a multimeter. The meter should measure around 4,000 ohms of resistance. Replace the diverter motor if the meter measure infinite resistance. If the diverter motor is okay, measure the resistance through the diverter position switch with the switch plunger pushed in and with the switch plunger extended. The meter should measure infinite resistance with the switch plunger in one position and near 0 ohms of resistance with the switch plunger in the opposite position. If the meter measures the same resistance regardless of switch plunger position, replace the diverter position switch because it isn't detecting diverter position Diverter motor, diverter position switch

Notes:

* If the wire connections are okay, disconnect the wires from the valve and check resistance through the water inlet valve using a multimeter. The meter should measure around 25 ohms of resistance.

** If the wiring connections are okay, disconnect the wires from the drain pump and check the resistance of the drain pump motor using a multimeter. The meter should measure between 4 and 5 ohms of resistance through the drain pump motor pins 1 and 2, pins 2 and 3 and pins 1 and 3. Replace the drain pump if the meter measures infinite resistance through any combination of pins.
