The above Boiler last night for some reason stopped working, due to its age theres only 1 power light on the front which had gone off, so i checked the 3 fuses in the front, as i pulled 1 out the light came back on but boiler still didn't work, i assume this is some kind of fail safe just need to know whats failed..
Update : ok, of the 3 fuses on the front panel, the T2a one has blown on the far left, i replaced it and the power was back, I tried the water, it instantly blew again, I have also checked that the pump runs freely and it does, anybody help please....

you need a multi meter to test pump,fan etc.the only other way is to check for water on or around parts disconnect pump, fan, divertor valve motor then reconnect in turn trying boiler each time (you could set up a external 3 amp fused supply to test them independantly of the boiler) this however is assuming it isn't faulty wiring or the pcb
