Hi, I just refilled my Sundance Chelsee after shutting it down for the month of August. After power up, the display shows an error code that is not consistent with those listed in the owner's manual. The LCD shows in sequence... -> all blank -> heat indicator LED flashes ON for 1 sec then off -> right LED flashes 4 for 1 sec then off -> left LED flashes 7 for 1 sec then off -> repeat All the pumps and lights work OK. and the water is heating up. It seems like it's telling me that it's at 74 degrees, just in a very unusual way. Can anyone offer some advice on what the problem may be? Thanks!
