Boiler not lighting - heating only affected

phughes64 · 14 Jan 2011

Hi everyone,

Am looking to get some advice. I've got an Ideal Icos HE12 boiler that isn't lighting up when instructed to heat the house.

When hot water is turned on, the boiler fires up.

The thermostat clicks when turning normally and the pressure in the system is a little over 1bar.

There are no error codes on the little LED display and I've completely powered the boiler and control unit off/on again.

Any ideas what else I can try?

Thanks in advance!
