Help! Went away for a week and left my mom in charge - yikes! Came home to find the heater isn't working. I have power and the control panel starts up then goes to water temp 82 off. I get nothing when I push any of the buttons. I have tried re-setting it (holding the mode button in, then the up/down arrows) and it resets - but goes back to the same screen (82 and "off"). Any ideas??? Someone suggested that the problem is the control board. Does that sound right?
