terminate the current cycle, turn off all outputs, and flash two LEDs one second on/one second off to indicate
the error.
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the washer before servicing.
• Never start the washer with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer is properly grounded.
• Motor not grounded! Disconnect electric power before servicing motor.
