Tub Heater
How do I fix my hot tub heater?

I have an older hot tub and the heater won’t turn on. I have replaced the heater, pressure switch, thermostat, filter and pump. I don’t know what to try next. The heater tries to turn on when I turn up the heat but then shuts right off. Any ideas?

Hello,

What make and model of controls do you have? If you would repost them I can help you. When you say it shuts off…does that mean it is tripping the gfi? If so then when you are giving it a demand for heat (heater turning on) the amp draw is either too much and causing it to trip or their is a fault with the brand new heater you have. I recently this week actually had two brand new heaters that were bad when replacing a customers bad heater. Depending on the age of your tub if it has Contactors…that might also be it. Post new info please.
