My ideal logic combi 30+ is saying ignition lockout and my radiatiors arent heating up as well as my water not turning hot. How can i fix this please?


Lockout is a safety feature. Usually a latching condition and needs to be investigated rather than blindly reset. (The Combi has a bit more intelligence.) With the ignition locked out, you can't hi-fire the boiler, so no hot water of either type. The 'L' should also show a code number - check your user manual (google) for more guidance.

I've had a lockout on a non-combi: it was caused by lack of circulation of central heating water through the boiler.... The system boiled and the trip tripped. The pump WAS running, but wear in a valve actuator resulted in the valve feedback saying valve open while it was physically shut.

What is "Ignition Lockout Fault?"


I wonder why your question ended up in the wrong category.

Now that we know that it is a propane heater and not a TV I still don't know the brand name or model. I think you said 5th. wheel.

What is a 1F code on the hayward pool heater


The code you are referring to is actually IF, not 1F. It stands for ignition failure.
If the control exceeds the maximum number of ignition retries or recycles the heater will shut down and go into lockout. Automatic reset is 60 minutes.

Ignition lockout


Make sure all gas is turned on to the heater, ignition lockout can be one of several things, the majority of the time its a control board but, it could also be water in the heat exchanger pot, which would keep the ignitor from working, or a bad igniter.

AO error


This error is produced when the blower prover switch does not close after the blower starts, the control will stop the ignition and go into lockout. Automatic reset is immediate after the blower prover switch closes.

If you keep having this problem, contact a reputable service company, especially if it's under warranty.

The link to the owners manual is below, it references fault codes, etc..

Hope this helps.

IF error ignition fault lockout


If it has not fired in some time, the odds are high that a small spider web is blocking the burner orifices. These are the brass fittings exposed at the front of the burner tray. It does not take much to block gas flow. Each burner should have a pipe cleaner run into the orifice. A small zip ties will also work. You're looking for a small web on the end of the cleaner.

The problem lies in the blockage. The ignitor and flame sensor sit at two different burners. Blockage of a burner at those locations will not ignite or will not sense flame to allow the heater to stay on.

Restart after cleaning and see what happens. Otherwise, you may have a bad ignitior.
