What is the flash sequence? How many times does it flash before it repeats
Continuous flash indicates a poor ground for the unit or reversed wiring polarity
Sounds like you reversed the polarity and you had the same flash sequence before and after? If so you need to confirm the unit's ground. If the problem continues you need to get an electrician to check the main panel ground
That's all I got. I'm going to open this up to my colleagues maybe one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.
