Some things to check :
1/ Is your hot water electric or gas
If it is gas you will need a plumber/gasfitter instead of an electrician.
2/ Is the rest of your power on?
It may be that there is power down in your area, Call Essential Energy on 13 20 80 for outages
3/ Are you the home owner?
If not, contact your landlord, real estate agent or government department responsible for your premises.
4/ Some older hot water services have an isolating switch near them on the wall. Check that this has not been
accidentally turned off.
