I have the Sundance optima hot tub. I’m getting two error messages. I have recently changed the heater and the sensor that plugs into the heater

    Marc the SN1 and SN3 messages are your hi limit and temp sensor messages. If you disconnected one or both of them from the sensor harness you will want to check your connections in the sensor harness so that they are not loose. If all else fails contact our Sundance Service Support Desk to book a diagnostic and repair of your Sundance Optima Spa.
