The LCD display on my Jandy Lite2 pool heater keeps flashing when turned on. First it dispaly everything when functioning normally and then changes to showing the number 113 in the bottom right hand corner. This keeps repeating until I turn it off. The heater is not working.
Error showing 113 - Had pro check it out, all systems normal (voltages, gas, etc.). Spent $310 and ordered new control assembly from Amazon (pool store wanted $425) installed myself in under 2mins and heater works perfectly again.

Check your heater by-pass valve and be sure it is almost closed. If not that then it will be your internal by-pass. These will force water through heater and keep it from overheating the water inside it and shuting it down. Also check to be sure the baskets are clean and the filter is clean.
