What to do if my HotSpring Sovereign IIE does not heat but jets and light operate?

If your HotSpring Hot Tub's jets and light are working, but the spa is not heating, it could be due to: * An open integrated pressure switch: 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. * The circulation pump thermal cut-off tripped: 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.
