when I turn the spa on it makes a buzz sound, then shuts off and the circuit breaker trips. the service button lights and the LO message appears on the heater unit.
any ideas ? I have left several messages with the Hayward service person but no response yet :(

How long has it been doing this? Check your wiring and make sure it's not grounding out. Breakers trip for a reason. It's probably grounding or overloaded. Is it sized properly?
