This washer gave great service for 27 years - I'd only had to replace the Lid Switch - but it started leaking water, dripping from the right-rear corner. The Inlet Valve and hoses were dry, so was the Washer Pump, and it's in the front, anyway... So, I kept the cover off, and started the machine on a low cycle - as soon as it started filling I could see the water dripping from under the center of the outer tub and running down the rear tub support leg to the rear frame.
(THIS WAS A STUPID THING TO DO - DON'T RUN THE MACHINE WITH THE COVER OFF - THE EXPOSED MECHANICAL AND ELECTRICAL PARTS CAN HURT OR KILL YOU)
It was pretty clear the problem was the outer tub Gasket (W10814296). So, I ordered that and the Tub Wrench (AP6832671), and got them the next day, which was amazing.
The repair video was very clear, and the job isn't really hard, but as others have noted, it does have a few challenges. Here are my notes:
1. Breaking the Spanner Nut loose and then removing the Basket can be difficult on an old machine. A lot of penetrating oil ("Liquid Wrench"), patience, and a 5-pound hammer eventually convinced the nut to come off, but the Basket and Drive Block had corroded firmly together. I ended-up reinstalling the Spanner Nut, and using a two-jaw automotive gear puller (with the jaws grabbing the nut and the screw bearing on the top of the agitator drive shaft) to remove the Basket and Drive Block from the shaft as a unit. Then I carefully drove the Drive Block out of the basket tube with a pipe drift and a hammer.
2. The Drive Block and Spanner Nut both cleaned up nicely using a fine wire brush wheel on a bench-top grinder. You have to be careful with the block, because it's aluminum. There was some pitting from the corrosion, but that didn't interfere with the blocks clamping function and the notches which mate with the tabs on the Basket Drive Shaft were undamaged, so I was able to reuse it. The inside and base of the basket tube were also badly rusted, so I cleaned them up with various scrapers and a small wire wheel on a shaft extension in an electric drill. Then I gave the bare metal a few coats of appliance paint, to at least slow down the progress of the rust.
2. The original "self-cleaning" lint filter (which is a large, complex plastic fitting on the bottom of the Basket) was a foul mess on my machine, encrusted with 25 years of hard water deposits, lint and dirt. It's held to the Basket by four plastic buttons which snap into holes in the basket tube. These were encrusted into the holes, but I removed the filter by using four flat screwdrivers to depress the buttons and hold them pressed-in. You can replace this whole fitting with the Washer Filter Plug Kit (AP3094570). This consists of four round filter plugs which snap into the drain holes on the bottom of the Basket, but I hadn't ordered these, so I painfully scrubbed the original filter and snapped it back in place (after the wire-brushing and painting of the basket).
3. The vertical tube on the Tub Support (around the Basket Drive Shaft and Agitator Drive Shaft) had rust "bumps" all around where the tub gasket seats, so I had to carefully file those off, then sand the tube smooth, and give it a few coats of appliance paint to slow down the progress of further rust and gave the gasket a smooth surface to seal against. The video says that you might need to use a scrubbing pad and some WD-40 to clean this part - it was a lot more work than that. After it was all cleaned and painted, I used some soap and water solution to lubricate it so the new tub gasket would slide easily when I reinstalled the outer tub.
4. Generally, on a machine this old, the cleaning will take more time than any other part of the repair. Just scrubbing the hard water deposits and dirt from the outside of the Basket, the inside of the Outer Tub, and the Tub Ring took a while, in addition to the rust removal, wire-brushing, and painting I've already described. I also used my air compressor to blow all the dust out of the motor and off the frame and everything else I could reach. I suppose you could just put everything back together dirty, but if you're not paying yourself by the hour, why not do the best job you can?
The leak repair was successful, and now I know the inside of the machine pretty well, so if anything else fails, it should be a pretty quick . Getting the parts from ApplianceParts Pros couldn't be easier and their instructional videos tell you everything you need to get started (although some improvisation may be necessary, particularly with an old machine.)
