Pool Error Code Lookup
Type a code, or part of one, to search every documented Hayward, Pentair, and Raypak code at once.
No matching code. Check the spelling, or browse by Hayward, Pentair, or Raypak instead — not every code a display can show is documented yet.
Not sure of the exact code?
If you haven't found the code yet, start from what the equipment is doing instead: heater won't ignite, pump won't prime, flow error, blank display, and the other symptom pages list every code that produces that behavior.
This site is an independent reference, not a substitute for a licensed pool professional. Gas pool heaters can leak carbon monoxide and cause fire; pump and heater electrical circuits carry mains voltage. Anything involving the gas line, burner assembly, or house wiring should be handled by a licensed technician or electrician.
