My Echo is out of warrantee and recently she has been very strange. She frequently doesn't respond to my voice commands and then shuts down and/or says she lost internet connection, which is fine with other devices. Could it be steam from shower (which is low as I keep door open in bathroom when shower is being used) or something else? She is acting like a misfiring robot from an 80s sitcom at times. I'm not sure what to do?
