Printed circuit board, if quick blow fuse hasn't blown, isolate electric supply, usually a 3 amp fused spur, remove fuse so no one can switch back on, then check inside electric compartment. Don't touch anything, just observe to see if glass fuse has blackened or burnt out, if so replace fuse, put front cover back on, then replace 3 amp fuse and hopefully you have power. If not, call Vaillant.
