Recently my Kenmore Series 80 washing machine has developed a grinding noise, which occurs just as the washing machine starts doing a spin out to remove the water. It last maybe 3 seconds, and then after that normal sounds of the water being emptied is all I hear. Last year I replaced the motor coupling, but am wondering if that might be what it is? Or what else might cause that problem?
You don't have a lot of info there. But it sounds like your bolt that is holding your main bearing for the main drum is coming loose. If it is a front load this is really easy to get to. Take off the back and you should see a large bearing. I had to replace mine for the same reason. It is held by one screw and has teeth that make the main drum spin. If the teeth are still in ok condition - which it just depends on how much you used it with that noise - then you just need to put the bolt all the way back in with blue loctite. If it isn't glued in it will works its way out quickly.
