Hello. I'm new to the forum so please forgive any mistakes I make. I also apologize for the long message. I have a 2005 Dim1 spa, Model Aurora II. It is a 220v system and has worked fine for 2 years. Now when I use it. especially at night, when the heater turns on and the pumps are running, after about 10 minutes the keypad is unresponsive, sometimes the pumps shut off and the unit goes into program mode. You can run through the program mode and get back to the main menu, but the unit immediately goes back to prograqm mode. Any button that is pushed on the control scrolls throught the program. After sitting this way for some period of time the thing resets and acts normal again. The only time I seem to be able to get it to mess up is when the temp falls anough for the heater to come on. I've checked everything I know and even emailed the company with no response. Any ideas? Thanks. Clint
