Hi Marty and Beaky, thanks for the replies.
Beaky, there are no LED's lighting up on the MPU. I checked for continuity on the plug and I'm pretty sure the circuit is not complete (I used the lowest resistance setting because I don't think my multimeter reads continuity). There was no change in the reading when I flicked the switch and I compared this to another machine which did change. So that means there is a problem with the power lead, the varistors, the fuse or the filter itself, right? The fuse is definitely OK, Can I test the other components?
