You are fine now. Count your lucky stars you got it right with only 1 incorrect wiring and the dimmer wasn't damaged. Glad you didn't mess with the other 2 switches. If you desire to replace them, ask here 1st. The 4 way switch can really screw you up even by buying the right switch.
Installing new dimmer switch
Hey all,
I just installed this new Lutron dimmer (here are the instructions):
https://images.homedepot-static.com/catalog/pdfImages/79/79453c8f-7450-44ad-8767-f2d3756ced89.pdf
The lights are controlled from 3 locations downstairs so I was following 3B and 4B in the instructions above.
However, I wasn't replacing a regular switch like it shows in the instructions, I was replacing an old dimmer, one very similar to this one:
https://www.leviton.com/en/products/61000-3i
So when it says to tag the common wire, I wasn't sure which one it was since the old dimmer only had 3 wires coming from it so I took an educated guess on which was the common and connected it to the black wire and connected the others as noted.
Turn power on, nothing....the lights wont come on from any of the 3 locations downstairs.
So after turning the power off again, I open the switch back up and I change the 2 connections. I hook the red up to the red this time, turn the power on and boom, it works! Not only from the new dimmer switch but all 3 locations like before.
My question is, if it's working now, does that mean it has to be hooked up properly? In other words, could it be hooked up wrong where it could be a safety hazard even though it appears to be working as intended? Or as long as it is working I have no worries?
Thanks!
Here is a diagram I drew in paint if it helps (I think its accurate):
