I have F13 flashing in the display what does this mean

Rhona, April 2012

I have the same fault. Apparantly if the power to the boiler has been interupted it can damage the main PCB (printed curcuit board) I'm in the process of inspecting the old one for obvious problems before sending for a new one which are very expensive. If I can find what the problem is I'll be making a small charge for repairs to faulty boards.

F13 fault
PCB connection fault
if you are lucky it might just be a loose wire or connector on the PCB that needs reconnecting
