Slow cold water fill, and sound insulation
Hi Louie, if the valve is trying to let cold water in, you can’t do anything with A multimeter, you have a bad inlet valve. I assume you checked the flow by taking the cold water, inlet hose, and directed it into the tub of the washer and turning it on full force if there’s great force there you have a Bad bad valve.
We have sound insulated many washing machines and dryers. It can make a good machine really pleasing to have around, Jason and I got into a competition with Jon from Boston after Jon added insulation to his 1to18 Frigidaire washer went a few steps further and have one that is almost silent, we added 40 pounds of insulation to the front panel alone we sealed nearly every seam and we even put a sound insulating block all the way around the bottom of the machine just inside the edge. This was a technique that Maytag used on the Norgetag machines. We also added a foam seal around the edge of the lid to keep noise inside the machine, when Jon C got to see our handiwork, he complained that he could still hear the timer motor, lol
I like the dynamite stuff you’re using, but I find it also helps to add a lot of weight to the panels. I’ve often use thick semi-flexible vinyl flooring, etc. and glue and tape that to the inside of the panels adding a lot of weight really dampens the noise when you knock on the front of this machine with your hand. It sounds more like fine furniture than a tiny metal box.
We also added a lot of very thin foam weatherstripping to the edges of the panels to keep noise in the machine.
