I am getting a code on the display of Lr The Machine goes Through the timed cycle and fills with water and empties but does not wash or spin. I suspect the motor control or the motor. Are there any procedure to isolate the problem?
Answer Hello David. The motor drive system experienced a momentary loss of neutral feed from the power cord to the
Motor Control Board. The neutral line for the Motor Control Board passes across the water valve
solenoids. Neutral to the motor drive system can be momentarily lost If there is poor crimping of any
of the wire terminals in this circuit. This situation could result in a misdiagnosis and unnecessary
replacement of the Motor or Motor Controller Board.
Current Neptune front load washers will indicate a false locked rotor signal to the Machine Control
Board. Washers with a LED display will flash code “LR” in the display. LCD washers will display
“Locked Rotor.” The earlier built front loaders will not display a code, but simply shut down in mid-cycle or will not start. Pull each terminal of the white wire harness connected to each water valve solenoid and verify the
wire is properly stripped and crimped to the metal terminal connector of the wire harness. Make sure
the wires fit snug on the terminals of the water valve solenoids.
