Twenty years ago I owned a washing machine with an attached green grounding wire. The manual stated this wire should be securely attached to a grounded object.
The washing machine we own today has no wire, and the owner's manual mentions nothing about one. However, there is a tapped hole on the back panel with the words " Ground Screw" stamped into the metal, but without a screw present!
The house wiring provides a dedicated branch for the washer, but is not GFCI protected. The water softener is also powered from the same receptacle.
Should I use this tapped hole, and ground the washer to a water pipe or receptacle box? Has there been revisions in code regarding washing machines? Are GFCI's generally used or not used on washing machines? Is the softener OK being plugged into the same receptacle as the washer?
