I was given a Freeflow passport spa three days ago. The spa is in great condition. Everything works perfectly except the heater.
Today is Saturday, I turned it on Wednesday to heat it up. It started out at 62° it is now at 75°. I have the cover on it while it's been heating but I don't think it's supposed to take this long to heat it a whopping 13° degrees.
It is running on 120 voltage. I know that it takes a little bit longer to heat using 120 volts but I wouldn't think a week to get to 100°.
any help or advice would be greatly appreciated.
