Yes, the wear marks with rust on the inside tub is normal, as well.
Whenever you have a stationary outer tub, and an inner tub that can literally bang into that porcelain tub, ..... without the benefit of at least a cushioned bumper, you know you have a design flaw.
And GE made these for 30 years.
Notice too: fill that tub with the water level set on high, open that top and take a look at the large volume of water on the OUTSIDE of the wash tub. That's why these are called water hogs.
and again, GE made these for 30 years.
They sure are fun though. The first washer I got back in 1983, was a trade-in 1970 avocado sudsaver GE with 4 toggle switches on the control panel, and a lit timer dial. It had a sock stuck in the pump.
Oh, notice the drain connection from the tub to the pump.
Is there any grill on that tube? Nope.
A sump under the tub to collect large things that could damage the pump? Nope.
Any type of device, anywhere, to protect the pump from getting damaged by large items? Nope, Nada, none.
Drop a 3" nail in the outer tub and you're screwed.
If your washer is in generally good condition, as it looks to be, it will have a filter flo smell, as well. I don't know how to explain it. I think its the combination of traditional Tide, Downy, and rubber mixed together. I love it. If they made an air freshner labeled 'traditional GE filter-flo', I'd buy it.
I recently acquired an Almond 1982 GE with 3 push button instead of toggles.
I opened the lid and smiled. It has 'the smell'. lol
Consider yourself lucky to have a filter-flo vs. a rim-flo. With the rim-flo, as was found on JCPenny and Hotpoint washers, the lint accumulated in the rim mounted lint filter and was supposed to awkwardly spin off, fall into the bottom of the machine, and somehow magically make it's way to the drain and be expelled.
But that's not how it worked.
What usually happened is the lint would get spun off the rim filter but it stuck to the outer tub wall, and there it accumulated. Sometimes, as it decayed it would slowly slide down the tub, and between wash loads, dry and form masses on the bottom of the tub.
Emm, yeah. Smell THAT. The smell of traditional GE filter-flo but with the tinge of wet dirty lint balls molding on the outer tub wall. Nah, we don't need to bottle that one.
