3-way dimmer switch doesn't work on GFCI circuit

Model: KS230 KIT

Hardware Version: V2

Firmware Version:

I installed this switch on a circuit that had a GFCI. The GFCI shut off the power as soon as I turned on the breaker. I tried a second KS230 kit with the same results. I then tried it on a circuit without a GFCI and it worked fine. Is this a limitation with this product or could it possibly be an issue with the GFCI or the circuit itself. I had no problems with standard 3-way switches.

@talbotyyc

What GFCI breaker are you using?

Can you share some pictures of the breaker and switch wiring here.

The GFCI is in the basement bathroom. The 3-way switches I am having difficulties with control 4 LED ceiling pot lights in the adjacent family room. The 3-way switches are on the load side of the GFCI. The original GFCI was an Eagle 15A GFCI. I thought it may be defective so I replaced it tonight with a Leviton GFNL1-W. Unfortunately, this did not correct the problem. The original 3-way switches are not dimmers. I have pictures of the GFCIs but I don't see where I can submit them. Thank you for your assitance.

BTW, may I know what light bulbs do you use? Do you know the brand, power, etc?
