Mend Glowworm 30 Cxi

glowworm 30 cxi?

my 2 year old glowworm 30cxi keeps going to f13 fault i have changed the main pcb and the display pcb and the door seal on the appliance. it is a condensing boiler which is always breaking down and up to now i have managed to fix it.

For the 30cxi manual 2000225213A page 38 gives F13 as Main board fault with no possible cause stated. Our 30cxi installed in Sep 2002 sometimes gives F9 Flashing when drawing hot tap water and no central heating demanded. The flow chart did not help much with this fault either. Recently the block (left-hand hydroblock?) behind the Reduced Pressure Zone Valve has developed pinhole water leaks that could cause worse flooding as they get larger. Certainly another Glow-worm design fault.
