I can hear the motor running, but there is no circulation or heat. My spa is not heating. My wooden hot tub was left empty for a year. Now it leaks like a sieve. Our winters get very cold.
Electrical repairs can be dangerous.
We recommend that electrical service be referred to a qualified technician. Regardless of who performs the work, make certain that all electrical power to the hot tub or spa is disconnected prior to making any inspections or repairs. The above information is provided for educational purposes only. If you hire a qualified technician, this will give you a better understanding of the diagnostic process involved. White flakes occasionally collect on the bottom of my spa.
