ILO or ROL. There is no EOL.

ROL is a switch inside the lower left corner of the heater. Press the red button. ILO is a lockout. Power down and power up.

Thank you for posting your question here on Fixya.com.

Replacing the roll out switch is an easy do-it-yourself repair. Fixing the problem causing the roll out of the burner flames in the first place is a bit more of a pro job. Something is causing to much heat to roll out the the combustion chamber into the control area causing the switch to fail. You will continue to burn the link until the underlying problem is fixed.

If this answer does not fix your problem, please comment with additional details prior to rating the answer. Positive feedback is appreciated once your problem is solved!

SOURCE: my raypak heater has error

This is in the limit string. This is the string of safty switches in the heater. (thermostat, highlimits, rollout switch and pressure switch) The pressure switch is the most common problem. If the water flow get's to be too little so the water inside the heater is going to overheat than this will shut the heater down. This can be caused if your heater by-pass is to far open and letting water go by the heater. The most common problem is clogged baskets or a dirty filter. Other than this you can follow the flow chart in your manuel to find the source of the problem but if it just started without obvious cause this would be my bet.
I hope this helped and good luck.

SOURCE: Raypak 2100 pool heater won't heat, PRS and HL2 error codes.

Well, I replaced the pressure switch with no joy. I tried all 5 levels of pressure 1-5 and every wiring combination. Finally, I returned the new $70 pressure switch and took the 2 wires and tied them together (jumped them). Here's the only downside...If you run your pump in backwash, recirc, waste, or any mode that would cause water to bypass the heater it MUST BE OFF. Otherwise, let it ride. It's working great and I hope to go into October weather permitting.

Raypak pool heater - error code is "FAN"


In models older than 07-07 it typically indicates a loss of the pilot light.
In models newer than 07-07 it is probably the air switch not being activated, or it has just failed. Check air switch tubing for secure connections.
