I have an Amana Washing machine that's driving me a little insane. When it fills the tub, it shuts off the water at the right level desired. If you walk away and forget to put the clothes in and leave the lid up, (it 's a top loader) there is a good chance you can come back later and find it overflowing. Or you find out in the morning when there's no hot water for your shower. This has happened twice in the last year. Lucky for me the thing is located on the sunporch! Have also noticed the thing wants to pour foam out of the drain standpipe on the last part of the final spin cycle. Since the foam is large in volume and light in weight it seems to fill up standpipe and overflow onto the floor. the standpipe is at least 48 inches off the floor. it's almost as if the washer isn't getting enough water during the rinse and spin to break down the suds. Possible water pressure valve? I want to install a flood alert system but won't do much good if I can't keep the suds off the floor!
