Found an appropriate repair manual online (the Internet is a fantastic info source and, as proven here, a great place to get parts), confirmed that it was ONLY cold water not feeding thus narrowed the problem to the mixing valve, ordered the replacement and received it within a couple days, turned off the external water valves and unplugged the washer from the electrical outlet, popped off the front of the washer (only two screws at the bottom), raised the top of the washer (again, only two screws under the front), disconnected the internal hose from the mixing valve (one tube clamp) and, after "labeling" the electrical connections to the bad mixing valve solenoids with a couple pieces of duct tape (!), disconnected them, and removed the one screw holding the valve panel to the washer and pulled it into the inside back of the washer. Removed the water connections to the external house valves using a pliers to initially turn them, then pulled the entire mounting plate out to replace the mixing valve (again, only one screw holding it in place). At that point, the repair was done and just did all the steps in reverse to get the washer whole again - before fastening the top down and the front panel in place, tested the water flow to make sure all was well...it was.
