I have got the same problem: but pressing the reset button no longer has any effect. When only hot water is on - it still shows CO, however when hot water and heating are both on, the CO doesn't appear any more, but the heating does not work (same as described above - works for a couple of seconds and then cuts off). Any ideas?

CHECK YOUR WORK, YOU EITHER HAVE THE POTENTIOMETER ON THE DISPLAY BOARD 180* UP SIDE DOWN (IT SHOULDNT SPIN 360*) OR WHEN YOU SWREWED THE THE PCB BACK ON YOU MAY HAVE TRAPPED OR DAMMAGED THE CO BUTTON.
