Customer Question
I have a Glowworm 70...
I have a Glowworm 70 FF boiler. It is not lighting and I am told it is the internal F2 fuse. The pump AND the PCB were replaced today. Still the fuse is blowing. The plumber does not know what to do now. He's coming back tomorrow but just wondered if anyone had any ideas on what to check next. Thanks (thermostat and timer replaced last year).

Anything with a motor can create a short and blow the fuse.

Try disconnecting the fan and seeing if it holds
