Disconnecting a washing machine isn't difficult but does require a little muscle. Use a hand dolly or a friend’s help, if one is available, to pull the washing machine away from the wall. Once the washing machine is pulled away from the wall disconnecting the washing machine is simple.
Note: Keep towels handy to clean up water that may run out of the supply lines or drain hose.
Step 1 - Unplug the Power
First, as with any appliance, disconnect the electrical cord from the socket in the event that there is any water spray. Once the electric cord is unplugged all that is left are the supply lines and the drain line.
Step 2 - Remove the Drain Line
The drain line for washing machines is generally unattached and is bent into a 'U' shape and rests in a dedicated drain line either to a drain field, septic tank, or sewer main. To unhook the drain line, simply pull it out of the dedicated line and place inside the washing machine basket to keep it out of the way.
Step 3 - Remove the Supply Lines
The supply lines are simply threaded onto plumbed in supply lines. These plumbed in lines should be recessed into the wall and have easily accessible valves. First, shut of the valves to cut the water supply off to the washing machine. Unthread the washing machine supply lines from the plumbed line. If necessary, use a small pipe wrench or pump pliers to loosen them first.
