The instructions are listed below but if you don't want to get involved in this job, go to Home Advisor a free referral service that connects homeowners with local prescreened plumbers.
Turn off the controls to the hot and cold water valves usually located behind or above the washing machine.
Unplug the machine's power cord. Disconnect the hot and cold water supply hoses at the water valves. If you have to move the washing machine to reach the hoses, carefully push the unit away from the wall so you can access the back where the hoses are located. Use a wrench if the hose fittings are rusty.
Connect the inlet side of the hot and cold solenoid valves to the hot and cold water valves where the washing machine water supply hoses were connected. Then connect the washing machine water supply hoses to the outlet side of the hot and cold water solenoid valves.
Connect the two electrical cords from the control box to the hot and cold solenoid valves.
Plug the control box into the 115-volt wall outlet where the washing machine was plugged in. Then plug the washing machine power cord into the control box.
Open the hot and cold water valves and check for leaks.
