Wow JWWebster, thanks for the reply!
I forgot to mention that I did have the timer reconditioned about 2 years ago because it would stop halfway through the rinse cycle. I could advance it with my finger but it wouldn't go on its own. When I got the timer back the machine worked as good as new ever since. So, it might not be the timer.
I will take the back off the machine tomorrow and look inside. I'm not familiar with any of the parts (I'm a girl - but not afraid of a screwdriver
but maybe I can see if the belt is worn etc.
I did manage to drain the rest of the water by taking the drain hose off the laundry tub and placing the end in a low pail. So I do know the drain hose is not plugged.
I will let you know what I find tomorrow. I'm so glad someone is familiar with my old machine! Thank you!
