LOCKED ROTOR ERROR CODE

Cause  The motor can not turn

Solution  Check for tub moving freely by hand. If does not move free it may have a bad tub bearing.

Check for cracked magnets on the rotor, stator windings resistance greater than 15 ohms or less than 5 ohms or a foreign item between tubs. 

Check for damaged clutch assy.  Check for proper assembly of rotor washer, some newer models have rotor washer inside the rotor and may be missing.

Some models have a hall sensor that will cause this error code if resistance is out of range.

Check Hall Sensor brown wire to red wire & brown wire to blue for 8-10 kohms & brown wire to yellow wire for 10-15 vdc.

Also check yellow wire to red wire & yellow wire to blue wire for 10 vdc pulses when spinning tub.

DETAILS BELOW:

1.) Unplug the unit.  Check the harness connections at the Main PCB and Stator.

 

2.) Check for any clothing items between the inner and outer tubs.

 

3.) Remove the rotor and inspect for cracked or loose magnets on the rotor.

 

 

4.) Unit still unplugged. Access the stator connector on the Main PCB. Disconnect the connector and check resistance from RED to BLUE, RED to YELLOW, and BLUE to YELLOW. The resistance should be between 5 to 15 ohms. All three readings should be relatively equal. If the resistance readings are correct, replace the Main PCB. If an open is read on any reading, access the connection at the stator and disconnect the harness. Measure the resistance of the stator itself.  If an open is not read at the stator, suspect a harness issue. If an open is read, replace the stator.

CHECK STATOR WINDINGS

RESISTANCE VALUES

The resistance values should be greater than 5 ohms and less than 15 ohms on each winding. All windings within  ± 1 ohms of each other.

EXAMPLE READINGS:

BLUE to YELLOW = 10 OHMS

BLUE to RED = 11 OHMS

 

RED to YELLOW = 10.4 OHMS
