Troubleshooting
1. Washer Motor Circuit
2. Troubleshooting Knocking Noise
If a frontload washer produces a noise similar to a
knock on a door, it might be due to a flat spot on
the belt. The knocking sound is made when the flat
spot hits the pulley. The knocking may occur
during a pulse spin and fade after reaching a
higher RPM.
To correct this condition, replace the belt.
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect all electric power to the machine and accessories before servicing.
• Close gas shut-off valve to gas dryer before servicing.
• Never start machine with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the machine is properly grounded.
• Washer motor not grounded! Disconnect electric power before servicing motor.
