Kenmore Washer Error Code F7 E1 — Motor Speed Sensor Not Detecting Rotation
What this means
The F7 E1 error code on Kenmore washers means the motor speed sensor (also called a tachometer or rotor position sensor) is not detecting rotation of the drive motor. The washer may stop mid-cycle or fail to agitate and spin. Common causes include a loose wiring connection to the sensor, a faulty sensor, or a seized drive motor.
Alternate codes: F7E1
Step-by-step fix
4 stepsCheck for an overloaded drum
Open the washer and remove some items if the load is very large or heavy. An overloaded drum can stall the motor and trigger this error. Restart the cycle with a smaller load.
As a rule of thumb, the drum should be no more than three-quarters full for optimal performance.
Reset the washer
Unplug the washer for 5 minutes and plug it back in. Run a diagnostic cycle by pressing a specific key sequence (consult your model's manual). This can clear a one-time glitch in the motor control.
On many Kenmore front-loaders, the diagnostic mode is entered by pressing three buttons in sequence — check your tech sheet behind the lower panel.
Inspect the motor speed sensor
Unplug the washer. Access the motor by removing the rear panel or bottom panel (depending on your model). Locate the rotor position sensor attached to the motor. Check that its wire harness is firmly connected and not damaged.
The sensor is typically a small round component mounted on the back of the stator with a two-wire connector.
Test and replace the sensor
Use a multimeter to measure resistance across the sensor terminals. A healthy sensor typically reads between 10–15 ohms. If the reading is open or significantly out of range, replace the sensor.
Write down your model number before ordering — Kenmore washer parts vary widely between manufacturers (Whirlpool, LG, Electrolux).
When to call a professional
If the sensor tests fine but the motor still won't spin, the drive motor itself or the motor control board may be defective. Motor replacement involves heavy lifting and electrical work best left to a professional.
