Check your high limit switch inside of the heater. Usually when the high limit switch pops it will take about 4 to 6 hours for it to reset itself without you resetting the system.

I have a Pentair 40,000 BTU pool and spa heater. It comes on and then shuts off in about a minute with an error code appearing in the readout. The error code is E05. What does this mean?


The heater is trying to light but cannot. Either the igniter is broken or you are not getting any gas to the igniter. Check to make sure your gas valves are on.

Your bypass valve is bad. Probably because you did not pay attention to your water chemistry. It is located where the pipes enter the heater. You remove it from the side of the manifold that is outside the heater. It is not a difficult job. Just make sure your pump does not come on while the heater manifold is open!

Heater will fire, will heat for one hour then shutdown. will get digital read out AGS. can turn heater off, let set for a while turn heater on will heat up for an hour and it will shutdown again.


you didn't indicate exact model but here is what the AGS is for.
Not sure if yours has a combustion blower or not, if so check that it's flow is not obstructed. If it doesn't make sure there are no debries in the flue area. Here is the troubleshooting from their manual. You can download a manual from www.jandy.com

3. No flame at burners. 3. Identify and correct loose wiring connections, or
problems with igniter, flame sensor , gas valve, or
ignition control.

My Jandy Laars Natural Gas pool heater (LJ250N)


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.
