On the covered Kenmore 722 series dishwasher, LE means Kenmore's service table lists this code as: locked up circulation pump motor. Unplug the dishwasher and look in the sump for debris blocking the impeller. Check the wiring connections on the pump and reconnect loose wires.
Differential
Likely causes of “Kenmore 722 series dishwasher code LE”, and how to tell them apart
- 1
An obstruction that stops the pump impeller spinning
What separates it The LE code appears and the circulation pump does not turn
How to confirm Unplug the dishwasher and look in the sump for debris blocking the impeller
- 2
Loose wiring on the circulation pump
What separates it The impeller is clear but the pump is intermittent
How to confirm Check the wiring connections on the pump and reconnect loose wires
- 3
Failed motor windings or a failed RPM sensor
What separates it Any resistance measurement is near 0 ohms or infinite
How to confirm Measure pins 1-2, 2-3 and 1-3, then pins 7-4 and 7-5
- 4
A control board that is not sending current to the motor
What separates it The motor, the sensor and their wires all measure correctly
How to confirm The chart replaces the control board if the wires on RD3 and WH4 read the same as the motor
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether debris is visible in the sump
- The motor winding resistance across the three pin pairs
- The RPM sensor resistance across pins 7-4 and 7-5
- Whether the pump hums but does not turn

ReversibleUnplug 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. If resistance through the motor windings and RPM sensor is good, plug the motor wire harness back in and measure resistance through the motor wires that connect to the electronic control board. Check resistance through the white and blue wires, the white and sky blue wires and the blue and sky blue wires on RD3. The meter should read the same resistance as for the motor windings.
Measure resistance through the red and gray wires, then the red and violet wires on WH4 to check RPM sensor resistance. The meter should read the same resistance as for the RPM sensor. If resistance through the motor wires connected to the electronic control board are good, then you'll likely need to replace the electronic control board because it's not sending current to the motor. Find and repair the motor wiring failure if the meter measures infinite resistance or near 0 ohms through the motor winding or RPM sensor wires.

Unplug the dishwasher and check for an obstruction that stops the impeller spinning
ReversibleRemove any debris or foreign objects from the sump, then check that the impeller turns freely.
Check the pump wiring, then measure the motor windings and the RPM sensor
ReversibleWindings across pins 1-2, 2-3 and 1-3 should measure 8 to 20 ohms. The RPM sensor across pins 7-4 and 7-5 should measure 8,000 to 10,000 ohms. Replace the circulation motor if any reading is near 0 ohms or infinite.
Measure the wires to the control board, then decide between the board and a wiring repair
ReversibleOn RD3 measure the white and blue, white and sky blue, and blue and sky blue wires; on WH4 the red and gray, and red and violet wires. If all match the motor and sensor, replace the board; repair the wiring if any reads infinite or near 0 ohms.
Model-specific
What is true of this model and not of its siblings
- Shown as
- LE (722 series table).
- Parts named by the chart
- Circulation pump motor and electronic control board.
Stop boundary
When this stops being a self-service repair
- !Wear gloves when clearing the sump, because broken glass is a common cause of a locked impeller
- !Stop and unplug before unplugging the motor harness
