Thank you for your answer Peccav.i
I am in Australia and at least I now know I have to pay the $100 for a call-out by a technician.
I was trying to avoid that payment if it was something I could do myself more cheaply.
The inlet/drain light is flashing but I have checked both these and reset the machine. Still the light flashes.
As I heard a bang, I assumed it must be fuse.
Thanks again,
