Resume: Dyson CR01, Switch on and it blows house circuit breakers, was working OK a week ago.
I took the earth lead off the mains suppressor and everything fired up OK, so assume its a short circuit on one of the components. The inner door open warning flashed up (has happened once before) and had to open/close the door numerous times to clear the message so I'm thinking that this may be where the fault lies or possibly its the mains suppressor itself - is that a logical approach?
Next move is to run through the various components one by one to try to isolate the faults location, again is this a good way to proceed? I am not fully conversant with electrical issues.
How do you access the 'service mode' on the control panel, watched the Dyson engineer repairing it and he had all kinds of feedback via the matrix display - can't remember if he used a service tool to do this.
