Pericinggod,

Here's some help :
Before attempting to gain access to the controls mounted within the control panel, place a protective cloth or pad on the cabinet top.
1. Disconnect the unit from the power source.
2. Remove the selector knobs by pulling straight off. ( you don't need to remove the selector switch knobs).
3. Remove the three screws which secure therear,top edge of the frame assembly to the end caps and rear shield. This will allow the frame assembly to roll forward, lay the frame assembly on the protective pad/cloth.
4. Remove the timer knob as follows:
Locate the hole with the timer knob shaft at the rear, center of the timer.
Using a small flat blade screwdriver, pry the rod located in this hole out to release the timer knob. The knob and skirt will then pull straight off.
5. To remove the timer, remove the timer wiring harness plug, Remove the screw and gently pry up on the tab located on the center of the timer body below the wire harness, and slide towards the inside of the machine. this releases the timer from the control panel shield".
This should be the part number for the proper timer for your washer,
