The cycle knob on my Kenmore 70s series washing machine is broken. I cannot turn it to pick an appropriate cycle. It just spins around without moving the "dot" to a new cycle. The push/pull mechanism on the knob to start and stop a load is also starting to give me issues. Can I replace the whole knob? If so, how?

Does it leak every time it's run, or only occasionally? It could be that the belt on the drain pump is going bad or is loose, so it works some times but not always. Could be that the belt broke or the drain failed, so it will always leak from now on. It's hard to say without actually taking it apart and having a look

Bad timer. Try to find a used one if possible, this item is a little expensive.

First, see the Sears Parts site for your washer:

Next, see the Whirlpool / Kenmore Service manual for top load, direct drive washers:

I hate to say it but it sounds like a Timer problem.

I'd use the troubleshooting section of the Service Manual and the timer testing procedures to confirm the problem.

Note that there are two types of timers with different procedures to remove them.

Also see the following for how to release the console for access to the timer and other controls.

It sounds as if the machine doesn't spin during the spin cycle. Normally the agitator stops spinning, fairly quickly, if the lid is opened during the spin cycle.That safety circuit includes a switch mounted under the opening and is set by a tab on the lid that protrudes thru a small hole in the top of the washer. The most likely failure on most Kenmore models is that switch, broken or loose, the tab on the lid broken, or the two misaligned. I would need the model number of your washer, located on a tag on the bottom of the lid to be more specific

There are two or three springs that hold the drum upright and level. They are attached to the motor and the drum base or sides. You have a broken spring. From being overloaded or turning during a last spin cycle it was out of balance and broke a spring. The machine will have to be taken apart to expose the springs. They are about 4-6" long. If the mounts are Ok replace all springs.

it's possible go to www.repairclinic.com and enter the numbers you have posted and it will show you what they are. I have the same problem. What I did was not pretty but it works for now. I broke a piece off of your part#387997 and simply turn my dial that way and then pull the center out to start the wash. Considering a new timer is close to $100+ and it works fine this way , well you know...
