About Ground Wires

In the event of an electrical short circuit, a ground wire reduces the risk of electric shock by providing an escape wire for the electric current.

Standard accepted color coding for ground wires is green or green with a yellow stripe.

Grounding wires and wires colored like grounding wires are NOT to be used as current carrying conductors.

!WARNING

To reduce the risk of fire, electric shock, serious injury or death, all wiring and grounding must conform with the latest edition of the National Electric Code, ANSI/ NFPA 70, or the Canadian Electrical Code, CSA C22.1, and such local regulations as might apply. It is the customer’s responsibility to have the wiring and fuses checked by a qualified electrician to make sure your home has adequate electrical power to operate the washer.

!WARNING

To avoid risk of personal injury or death due to electrical shock:

Observe all local codes and ordinances.

Disconnect electrical power to unit before servicing.

Ground appliance properly.

Check with a qualified electrician if you are not sure this appliance is properly grounded.

DO NOT ground to gas line.

DO NOT ground to cold water pipe if pipe is interrupted by plastic, nonmetallic gaskets, or other insulating (nonconducting) materials.

DO NOT modify plug on power cord. If plug does not fit electrical outlet, have proper outlet installed

by qualified electrician.

DO NOT have a fuse in the neutral or ground circuit. A fuse in the neutral or ground circuit could result in an electrical shock.

DO NOT use an extension cord with this appliance.

DO NOT use an adapter plug with this appliance.
