The washing machine would not agitate on the cycle most used by my wife.

After reading repair stories from others on the website, I was well prepared to remove the timer. I unplugged the machine from the electrical outlet and pryed out the center cover of the timer knobs with a pocket knife, removed the holding clip from the shaft and removed the two knobs and spring. I then removed the four screws from the top of the control panel, lifted the panel slightly upward and tipped the panel forward. With the aid of a pocket knife I then removed the two electrical connectors from the timer while depressing the plastic locking tabs. The control panel was then tipped upright and the two machine screws holding the timer were removed at the front. The timer was then free to be removed from the control panel. The new timer was installed in the reverse order of the removal. The old timer appeared to be working but had some signs of corrosion which was probably not allowing some of the electrical contacts to make a good connection. I attempted to clean the contacts but this did not help and decided this would only be a temporary fix if I did get it to work again.
