The timer appears to have run through all cycles if you look at the dial but when you open the lid (top load) the washer is full of water. If I turn the knob back around to spin, it will drain & spin. If I open the lid, stick a pen in the lid switch hole, the washer will advance through all cycles properly. Water coming out if discharge hose during draining totally fills hose so I don't believe it is blocked. Any ideas appreciated!

I had the same problem today. It first appeared that the lid switch wasn't working every time. Sometimes, spinning the timer around seemed to solve the problem, but not always.

But when I tried closing the lid in different ways (gently, or push at the back) I could control how it worked.

It finally became apparent that the rubber stopper around the post that activates the lid switch had hardened after many years, causing the lid switch to barely work, and sometimes not work at all.

I took off the rubber stopper and shaved about a millimeter (1/16") off it and put it back on. It works fine now.
