Response to Hi Zah, The ESG Heater Manual indicates that this issue can be caused by either the Pilot Generator, Redundant High Limit Switch, Wire Harness or Gas Valve being bad. I would recommend contacting a pool professional to inspect you unit to find out which one of these is causing the pilot nit to stay lit.
