it just seemed really good water pressure made the filling kinda whistle, annoying yes, I took out the air gap and with a few pieces of plastic pipe replaced it to make it a solid, no air gap hookup...alls you heard then was gushing water...
My buddy got these when I lived with him in princeton,nj, he bought fixer uppers and resold and made a pretty penny doing it back then, whe he remodeled the kitchen I talked him into new washer/dryer and all in the GE series, I like the "spotscrubber" with the large mini-basket which was solid, no holes in the bottom or near the center shaft, thats how I found out they would shut the filter flo off to concentrate the detergent in the mini-basket....the salesman didn't even know this, I only got to use them for about 2 years, very nice set though, I like gadgets and buttons....
I explained in the other thread on what to check on thewater spin out problem....check and get back to me...email if you have to, we'll figure out whats wrong.....adjust the water level set screw to allow enough water to about 1/2 below the filter pan, you can't let water float in the pan cause then the lint won't bundle up, it has to be able to flo out with the agitation strokes....now if your doesn't have the mini-basket, I think I have a tub filter ring from a hotpoint that could be used and that would allow you to fill the water even higher yet and still function with the filtering action, the advantage of this is the filter is self-cleaning....just some ideas....let me know how you made out.......
