My boiler has had an intermittent D1 code for some time, numerous parts replaced, condence trap, condense assembley, condence sensor, and a sensor (black thing) that fits onto the fan, all since May to no avail.
But yesterday I noticed that when the boiler fires up, the red light flashes once not giving a code at all, then eventually it cuts out on the D1 code.
I personally think it is the pcb board but my home assistance wont come out and put right the same fault that is on going that should have been done in may.
Any ideas?
