Product review (5 stars): Maytag washer water inlet valve
I watched a video online on how to replace this valve.  It was easy to replace, fixed the problem (hot water came in a trickle (filters were clean)), and is working great so far.  (My machine had a second problem, which the new pressure through the inlet hose made worse.  These old machines have an "air trap valve" in the hose line.  Mine was old and was apparently leaking a bit, then leaked a lot when the valve let full pressure come through the line.  It was another simple repair, but I got that part at an appliance store because I wanted it same day.)
