Removed front access panel--very easy, two screws at bottom of panel, near the floor. Removed two more hex-headed screws that secure the top panel/lid to the top of the washing machine frame.
Most difficult problem was identifying the source of the leak. I saw water running out of a white, rectangular (about 1" x 3/4" x 3/4") box-like device that was installed in the water line that leads from the mixing valve (blue box, mounted at the back of washer) to the top of the tub. Discovered this device is called the injector assembly, have not yet been able to figure out what function it serves.
Disconnected one of the hose clamps that secure the injector assembly to the water hose. Removed the rubber injector valve and injector nozzle, the two parts that fit inside the above-described "box." Soaked the assembly "box" in vinegar to eliminate hard-water deposits. Replaced the two internal parts (injector nozzle & injector valve) with new (about $15, including shipping). This almost resolved the problem, still saw a small amount of water leaking from the whole assembly, but only about 5% of what was leaking. Haven't yet figured out why it's not completely dry, or what function that injector assembly serves.
