    Does it matter which location you install the dimmer in a 3-way?

    I installed a Diva dimmer and Claro switch in two locations using the existing wiring. The switches both work independently for turning on and off the light, but the dimmer does not work at all.

    1) If I swap the dimmer and switch will the dimmer work correctly?

    2) Is there a way to keep the dimmer in its current location and get it to work correctly using the existing wiring?

    Thanks

    If you only have 2 locations, the dimmer can go at either location. If you have 3 or more locations, it can only go at the beginning or end.

    On the 3-way switch there is a black screw. This should either have the power coming into the circuit or the wire going up to the light.

    On the dimmer, the black wire should connect to the wire that was on the black screw of the switch you replaced.
