Always read the manufacturer’s instructions before installing a new appliance. The machine will most likely have brackets in place inside the drum to hold it in position while in transit. These will need to be removed before use or it will break the machine, see the manufacturer’s instructions for further detail.
Carefully remove the packaging from your new washing machine using a utility knife where required. Position the new washing machine in place. Reattach the cold water feed to the back of the new washing machine.
