ferroli F30


Hail,
I seem to be having a problem with an f30 boiler. The fireing up of the hot water and the ch lasts only approx 5 seconds and the stops.

I have bled all radiators for air locks and there is none to be found. It now does not fire up itself unless i reset, then it only lasts for 4-5 seconds. When it does fire up for the 4-5 secounds everything seems ok, but it just wont stay on. Would this be down to the sensor?

Any help would be of use

Hi

You need to check the ignition pressure setting first, as from what you have said it sounds like a flame rectification problem. The burner lights but the flame is not sensed by the sensing electrode. (does it try to re ignite itself?)

If this is Ok I would look at the condition of the sensing elctrode itself for cracks, positioning etc. also check if the burner is clean in this area.

Hi Dan,
nope it does not reignite, and at the same time the green light stays on.

Just to let you all know if this is the problem you are having it is the thermisters that are causeing this problem.

They speak to each other and if one is gone then that is the reason they dont work.
You have to change both at the same time at a cost of approx 120.

Hi Phil,

You should talk again to the person who gave you this advice.

The thermisters talk independently to the pcb with resistance. There is one for central heating and one for domestic hot water.

Most importantly they cost no more than 15 each.

I'd check to see if the air flow switches stay closed

if it has any, you may have some type of exhaust restriction
