Hi I have an Optimax HE38C Model less than 15 months old Showing A1 fault has been going off in the middle of the night for the last week (thought it was gas pressure low on main) went off this morning but won't restart water pressure above 1.2bar syphon filled and unblocked, ignitor clean no engineer available until next Monday cant get through to Ferrolli technical any suggestions?

Thanks

had mine repaired, was a faulty gas value, either way you have to call an engineer out to look at it
