What to do if my HotSpring PRODIGY H is not heating up, but the jets and light are working?
- AAngela JonesAug 20, 2025
If your HotSpring Hot Tub isn't heating up, but the jets and light are working, with the Green logo "Ready" and Blue logo "Power" indicators blinking, it could be due to an open integrated pressure switch or a tripped circulation pump thermal cut-off. Here’s what you should do: * Check for clogged filters. The integrated pressure switch will reset when the flow of water through the heater has been restored. Call for service if the heater trips frequently. * Check for clogged filters or air locks in plumbing. Disconnect power to the spa and allow the circulation pump to cool. The circulation pump thermal cut-off will reset when the pump has cooled and power is reapplied. Call for service if the circulation pump thermal cut-off trips frequently.
