I have a bit of a worry that WB might not repair my boiler again, if I haven't rectified the things on the notice. Though, as I said, I am pretty certain the position of the oil tank isn't an issue. David

The man from WB came, and eventually replaced the PCB and got it working. It was gratifying that we (myself and you) had diagnosed the right problem. He also replaced almost everything else so we have now got a mostly new boiler:D On the down side, he left us with a notice, and a sticker on...

The motor live and neutral seems to be wired to the PCB connector X12 via the blue bundle. It doesn't look like it is dependent on a feed from the burner control box (TF830), though it's neutral wire is connected to one of the TF830 pins. That is why I tried it without the TF830 connected, and...

I reconnected the motor and left the igniter off, and it still blows a fuse. I unplugged the blue cable bundle, fuse OK. So, it is reconnecting the motor that blows the fuse, even though the motor appears to work fine when powered directly from the mains. I am wondering if wiring in the...

I think the locating lugs have broken off, but I still think it is worth a try reconnecting the motor and seeing if the boiler is happy without the igniter unit. As I said, I reconnected the igniter to the spark leads on the boiler, so I assuming the spark should happen and that I would hear it...

I have plugged the motor in, it seems to work fine and didn't blow the 3 amp fuse in the plug. I tried the same with the ignition unit, and it did seem to blow the first 3 amp fuse I tried. I realised I hadn't actually tried that fuse beforehand in anything else (it was from an open packet)...

I have been too busy with work today, so I am making a start tomorrow morning. First I will try the motor from the mains, second try the ignition unit from the mains. If either blow the plug fuse, I will assume they need replacing. David

OK, thanks for that. I will try the motor tomorrow - I have been up since 4am, for work at 5am, so I am flagging a bit now. Can I test the motor in-situ or should I be removing the whole burner unit from the boiler? How would I test for a spark, do I just need to supply a constant 240v to the...

Thanks for the reply. The igniter doesn't look damaged, or smell. Do I need to remove the burner motor to test it, could I just wire it straight to a plug with a 13 amp fuse and see what happened? I was just wondering what the normal sequence of operations is for the burner. Would the...

I replaced the fuse, tried unplugging the blue burner cable, and it powered up OK. I connected the burner cable up again and it blew again. I went inside the wiring box, behind the control unit and disconnected the transformer, fan and oil pump wires: the fuse did not blow. I reconnected the...
