Can you see the agitator going up and down when you turn the tub?
Yes, if I would spin the tub, the pulsator would go up and down.
I decided to take the plunge and took Robert's advice tonight. Unfortunately the original drain hoses were not in great shape. I trimmed down the hose from the pump outlet to the garden hose connector to at least allow water to travel through it for this test. I then cut the petrified drain hose to about 3 feet long, and poured about 16 ounces of HOT water into the pump. Then I placed the original drain hook in the hose and set the bucket underneath. I let it sit for about 10 minutes, did a few hail marry's - and plugged her in.
The first pass the motor was locked up. Waited 20 seconds, tried again - still locked up.
I thought I'd give it a third shot, and BAM, I heard some garbling! I looked in the bucket that I had placed under the remaining 3 feet of water and saw some nasty gunk that had flown out. The mechanism had worked itself free!
I then cut the threaded end off of a bad inlet hose, and stuck it along the backside of the wash tub so I could pour some hot water in the outer tub. I got about 2 gallons processed and the pump was flowing out clear water.
Then came time for a spin test. Engaged the spin, could hear the solenoid engage, and .... nothing. The machine continued to agitate and the was just coasting at a snails pace - hardly 1140 RPM. What does this mean, to those who might not be quite 100 percent about the Unimatic mechanism? Let's find out from the Frigidaire doctrine.
