My washing machine will do nothing when you pull the knob to start it. I checked it is plugged in. It is a kenmore series 80. this washer is a great washer but it is probably 12or 13 years ago. i bought it used 10 years ago.

If this is a top load washer; then the "LID Switch" is broken. Go to www.sears.com/parts, enter your model number and you'll see the switch listed.

check your timer motor. if the front indicator knob isn't rotating or you don't hear a motor noise it will more than likely be the problem.

This assumes that you have a basic Kenmore / Whirlpool top load, direct drive, neutral drain (it doesn't spin until the pump removes most of the water) machine.

First, see the Sears parts site for your washer(s):

Enter the model number (###.######) and you'll see a list of major sub-components with diagrams and parts.

Check the part numbers for both machines in the "Console" section.

Also see the following Whirl[pool Service manual for top load, direct drive washers.

Whirlpool top load, washers use one of two different timers. Depending on the timer the knob comes off differently.

For most, by holding the back of the timer shaft with a thin needle nosed pliers, the knob unscrews.

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

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.

if it is a direct drive system, it could be the coupler. Maybe a $15 dollar part at sears online parts shop. There is a good video on you tube showing the coupler fix.
