OK, very good. Just wanted to make sure no GFCI was present.
1) 1st off, remove any and all jewelry that you may be wearing as you don't want to have these accidentally come into contact inside the electrical panel. Safety first:)
2) Remove the panel door screws and locate the branch circuit breaker. Reset the breaker to OFF and then to the ON position. Will either be a 15 or preferably a 20 amp single pole breaker.
3) Set your meter to the same setting as when you tested the receptacle. Place 1 meter probe to the branch circuit breaker screw terminal (where the hot wire terminates) and the other meter probe to the main neutral bus bar inside the panel (the bar that has all of the white neutral wires terminated to it). Should = approximately 120 volts.
4) Next, repeat the same at the circuit breaker and place the other meter probe directly to the panel metal enclosure. This will measure from Hot to Ground. Should also = approximately 120 volts.
5) If you get two 120 volt readings at the circuit breaker, this confirms the breaker is good and the open hot conductor is downstream from the main electrical panel (towards the washing machine receptacle).
6) What is the wiring
scheme that was used? Is the circuit wired using metal conduit
or Romex cable or some other type of cable such as BX?
7) Was any recent electrical work performed in the home such as swapping out switches or receptacles, etc?
Let me know the voltage measurements on the breaker......Thanks!
