Third empty the tank, we are using simple drill powered pump. Its handy to have a dust sheet around just in case of any leaks. Fourth step is to disconnect faulty immersion heater and remove it from cylinder. Fifth step is to apply seal around thread of replacement immersion heater so there is no water leak after cylinder is filled with water. Sixth step is to put in the replacement immersion heater and slowly while checking for leaks fill the cylinder. Open hot water tap fully and make sure cylinder is bled of any air. Seventh step is to reconnect wiring and carry out electrical safety checks. Eight step put power on and with current meter check what current it draws.
