Ground fault communication problem?

[JShaw01]

I am having trouble with 3 switches that get power from a bathroom ground fault detector. If I remove the ground fault from the circuit the switches get the signal and work fine , but if the ground fault is in the circuit the switches don't reply and no communication occurs. I purchased a new ground fault but the same thing occurs. Is there a work around to still use the ground fault?

If you have a Dual Band plug in module or Range Extender. You may want to try plugging it in a few spots and see if it helps.

Only outlets in the bathroom require GFCI's the lights and fan don't.  I'd rewire the circuit so that the GFCI is not feeding the switches (i.e. don't use the load terminals of the GFCI instead pigtail the power feeding the switches into the same wires feeding the outlet.   Make sure that you change any other down stream outlets that are currently being protected via that GFCI to individual GFCI's.  

I prefer not using the load terminals on the GFCI's most of the time, it's much simpler to use more GFCI's instead.  Then when they trip you don't lose the lighting in the bathroom too, or like in one prior house I had (before NEC changed), if you tripped the GFCI for the master bath you had to go downstairs to the half bath off the kitchen to press the reset button.

What is the brand and model of GFCI? Also you may consider installing a GFCI breaker at the main panel.

The only downside is they are more expensive and may not solve the issue. But if history is any indicator there have been very few cases of GFCI breakers causing the same issues.
