Kenmore 80 Series washer wont turn on from the push-pull knob.

You gotta pull out a rod behind the timer and that releases the knob. The rod when pushed into the timer spreads the shaft and holds it on there. To get to the innards you gotta flip up the controls. I have a cool video that shows how

you have a clogged pump
the pump is hooked directly to the motor if thats cogged the motor cannot move producing a humming sound

There should be a spring clip that holds the timer knob on. It or the timer knob may need replaced. Here is a picture of the timer knob and the spring clip. Sure hope this helps and best wishes.

if you pull on the knob it will come off it has a metal clip that is pretty snug on the stem but it will come off, you still have to take the cack cover plate off to get to the switch and do the actual replacement

I was just trying the same thing. I have a kenmore 80 series that wont even start to fill. i thought maybe the dial component was broke so i wanted to take it out. it was held on by a screw. I am not sure if there is a certain position the knob must be in, but mine turned counterclockwise. i have a feel for things like this so i might have done something else out of instict. but it is held on by a screw.

Something in the timer came apart. Timer needs replaced. When in good working order, the timer should ONLY ever be turned clockwise..Reversing this could break it.

Your timer has failed to initiate a pause for the transmission to lock in.
Replace your timer. Solve your problem.

check your hoses all the connections. you'll have to pull the part with the knobs off to do this inside. If it isn't turning, but the motor runs, it might be the coupler in the bottom of the washer connecting the motor and transmission.

If you are talking about the Cycle Selection knob, turn the washer to an OFF position, or unplug. I can't remember if you need to pull the knob out or leave pushed in, but the knob will come off by turning it counter-clockwise. After unscrewing it and removing, the plastic dial under the center knob will simply pull off. I hope this helps you. If you need further assistance, please let me know.
