I have the same issue that Waross mentions in this post. I have a Hot Springs spa sovereign with an IQ 2020. I just replaced the heater and still no heat. The LED on the IQ for the heater goes on for a few minutes then goes out. The spa never get warm. Dan the spa man says "You will need a meter to test the continuity of the heater and voltage at the heater relay", but does not give any details. What should the voltage at the heater terminals be? I only have a few volts. How do I test the relays? How do I test continuity of the heater? Thanks, Steve
