Our first issue with this unit I resolved 2 weeks ago or so with the help of you folks here. I was getting an IF code and wound up replacing the damaged igniter, that didn't do the trick so I bought a new control panel from Pool zoom and it worked like a brand new unit, until today. I didn't use the heater for a week or so because of some rain and the weather was hot. I selected the temperature setting (we have a digital control pad). The heater sounded like it tried to ignite once and then threw an LO code that won't be cleared. Now what? I looked over the manual and it's showing everything from insufficient flow, to some electrical issues. I cleaned the skimmer baskets and the basket before the return into the filter. I back washed and rinsed the filter and same "LO" code. Any suggestions before I just break down and call somebody to fix it?
