Electrical – 3 way dimmer on 4 way circuit

dimmer-switchelectrical

I have a 4 way circuit with 6 total switches light switches. One is a dimmer switch. The other 5 switches only work properly when the dimmer switch is on. If the dimmer switch is off the other toggle switches do nothing. Can't turn light on or off.

Also the toggle switches must all be in the on position in order to be able to turn the light on from the dimmer switch. What I mean by this is that if the lights are turned off using one of the toggle switches, and then I try to turn the light on from the dimmer switch, I will need to elk over to one of the toggle switches to turn the light back on.

Hope you can help! I realize that if the dimmer is dimmed, the toggle switches will turn the lights on dimmed, but it would be nice to be able to use all the switches for on/off.

Looking at the Installation Instructions, if you bought the 3-way version then you either miswired it, or tried to install it in place of one of the 4-way switches previously in the circuit. The 3-way dimmer must be at one end or the other of the circuit. (if you bought a single pole aka 2-way, then it'll never work).

This little pic shows the layout. The solid red bars are for one position of each 4-way; the dashed bars are for the other. So long as this particular 3-way dimmer is in one of the 3-way locations, it always passes the "dimmed" voltage to its live leg. enter image description here
