My Ideal ISAR m30100 is showing the 'FL' failure code, meaning that the boiler is failing to light. The water pressure showed below 0,5 bar, so I filled the system to above the reqd 1 bar mark, thinking this might be the issue, went thru the restart procedure, but still no joy. Any ideas?
Is there any sparking? If not - boiler could need reset (usually a red button hidden under / on top of boiler somewhere). Other possibility if reset doesn't work is that the spark ignitor has a loose connection or is gubbed, e.g get a new one.
If it's sparking but wont stay lit, could be the thermocouple valve, which is really common, and fairly easy to replace if you find a basic manual.
I'm a girly girl and I can do these things, so no excuses! xx
