Tonight the house started to feel a little cold. Felt the radiators and they were cold - went to the boiler WB 40cdi conventional and the display was flashing a very odd symbol like half a square in the upper left corner and the same in the lower right corner - L shapes into the edges of the display if you like. I turned the dial on the boiler and it started up again. The blue light remained on all this time.
I can't find anything in the user instructions about this and wondered if anyone knew what this meant.
Thanks
