This is my third repair of this type. The first was a stand-alone washer and was very easy, because there was a plate on which the inlet valve assembly was mounted, and it was easily removed. This repair was on a Frigidaire stacked washer/dryer (laundry center). Stacked washer/dryers are typically purchased to save space and are often tucked into a closet. Be sure you can pull it out to access both front and rear. Remove drain hose from drain, detach water hoses, electricity and dryer vent pipe. (Clean up water.) This washer/dryer had no access to the inside from the rear; the only access was the slot through which the valve assembly protruded. Loosen screws holding the assembly. Remove lower front cover. Reach around tub to the back and remove electrical wire clips. Have another person pull the assembly slightly down and push to the rear. Use needle-nose pliers to loosen the hose clip on the filler hose and move it upward through the tiny hole on the back. Try to get both arms into front of washer to hold valve assembly and fill hose to pull them apart. (Treat cuts and scrapes on arms.) Do the same to insert hose on new assembly. Have another person hold the assembly to the rear while you use needle-nose pliers to pull hose clamp into place through the tiny hole on the back. Have the helper push the fill ports through the slot in the back and hold tightly while you turn the thread cutting screws into the assembly to hold it in place. (Best to have the screws cut the threads at your workbench before installing.) Connect all hoses and electrical clips; try hot and cold water. Replace front panel. A trip to my local appliance store revealed that none of the stacked washer/dryer combos on the floor had an access panel in the back.
