Quick answer
Pilot flame not established, or lost during trial for main burner
Severity: high · DIY difficulty: easy
Safety
Stop at the exterior: power-cycle at the disconnect, clean the filter/basket, and check for obvious water-flow blockage. Pool heaters combine gas piping, 240 V wiring, and (on heat pumps) refrigerant — burner, control-board, and sealed-system work requires a licensed technician. If you smell gas, shut the gas valve and leave the area first.
What Ignition Lockout means
Pilot flame not established, or lost during trial for main burner
Code meaning varies by series
- Digital 206A-406A / Low NOx / Professional / Above-Ground: Alternating with 'No pilot sensed' - pilot flame not established within the required time (15 sec or 90 sec), or alternating with 'Main Ign Failure' - pilot flame lost during the 8 second trial to ignite the main burner (Propane Tab Broken).
First checks before service
1. One-time fault event (power disturbance or transient sensor reading) common DIY
Check: Power-cycle at the breaker/disconnect (or unplug for CPAP), restore, and run the system while watching for the code.
Fix: If the code does not return after a full run cycle, the fault was transient — monitor, no repair needed.
2. Fault persists after a clean reset occasional pro only
Check: If the code returns immediately or every session, note the conditions (startup, heating, after rain).
Fix: A persisting code points at the component the manual assigns to this code — that repair is technician territory.
