A few weeks ago however, the A408 developed a squealing sound from the water valve, which was fairly benign until it worsened into a flutter that caused a water hammer oscillation this past week.
I took the valve assembly apart, cleaned it, ensured it was free of debris in the screens and ports in the diaphragms, and re-assembled. I also cleaned the electrical contacts. This unfortunately wasn't enough to resolve the issue, and it appears that Maytag declared these valves "non-serviceable", so replacement diaphragms are not available. I'll have to replace the entire valve.

In the meantime, I've swapped the wiring and hoses, so that the "bad" valve is on the hot side instead of the cold, so the machine can continue being used for cold/cold washes. The injector hose leaked on reassembly, but it seems fine now after cutting off a half-inch (so it's fresh hose over the barb).
