Roper Washer Error Code F7E6: Motor Circuit Fault... | appliancefaults.com

Technical Background:

The F7E6 error code indicates a problem within the motor control circuit. The MCU (Motor Control Unit) monitors the motor's operation, including voltage, current, and speed. If the MCU detects an abnormality, such as overcurrent, short circuit, or open circuit in the motor windings or associated wiring, it triggers the F7E6 error code.

Symptoms:

The Roper washer displays error code F7E6 and may not start or complete a cycle. The motor might not turn, or the washer may stop mid-cycle.

Possible Causes:

Motor windings shorted or open.
Wiring harness damaged or loose connection.
Motor control unit (MCU) failure.
Stator failure.
Rotor failure.
Obstruction preventing motor rotation.

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Access the motor and MCU (usually located at the bottom of the washer). Use a 1/4-inch nut driver to remove access panels.
3

Inspect the wiring harness connecting the motor to the MCU for any visible damage (cuts, pinched wires). Ensure the connections are secure.
4

Use a multimeter to check the motor windings for continuity. You should find a low resistance value (typically a few ohms) between each winding. An open circuit indicates a faulty winding.
5

Check the voltage supply to the motor from the MCU during a wash cycle using a multimeter. Expect to see varying AC voltage (potentially up to 120V AC) depending on the motor speed.
6

If the wiring and motor windings appear good, suspect a faulty MCU. Replacement may be necessary. Part numbers can usually be found on the MCU label.
7

Check for any physical obstructions preventing the motor from turning. Remove the belt (if applicable) and try turning the motor shaft by hand. It should rotate freely.

Safety Warning:

Disconnect power to the washer before performing any repairs. Use proper lockout/tagout (LOTO) procedures to prevent accidental energizing of the appliance. High voltage is present in the motor circuit; exercise caution when testing.

Prevention:

Regularly inspect the washer's wiring harness for wear and tear. Ensure the washer is not overloaded with clothes, as this can strain the motor. Clean the drain pump filter to prevent obstructions.

Expert Tip:

Some Roper washers have a diagnostic mode. Simultaneously press and hold the Start/Pause and End Cycle buttons for 3 seconds to enter diagnostic mode. This may provide more specific error information.

Frequently Asked Questions

•What is the typical resistance range for the motor windings?

The typical resistance range for the motor windings is usually between 2 to 8 ohms, but this can vary depending on the motor. Check the technical service manual for your specific Roper washer model for the precise values.

•How do I test the motor control unit (MCU) if I don't have a service manual?

Without a service manual, testing the MCU can be difficult. However, you can check for obvious signs of damage like burned components or bulging capacitors. Ensure the MCU is receiving the correct input voltage (typically 120V AC). If the wiring and motor are good, but the MCU is not sending the correct voltage to the motor, replacement is likely required.

•Where can I find replacement parts for my Roper washer?

You can find replacement parts for your Roper washer at appliance parts retailers like AppliancePartsPros.com, RepairClinic.com, or through authorized Roper appliance dealers. Be sure to have your washer's model number ready to ensure you get the correct parts.
