Disassemble the control panel. Pretty straight forward.
There is a wiring harness plugged into the left side of the timer box. Leave this for now.
Remove the front knob by screwing it counter clock-wise.
The ring\clip assembly that advances through the cycles pulls straight off the threaded shaft.
Note the 2 splines on the clip that correctly align the ring\clip with the timer\cycle shaft.
Remove the 2 metal screws securing the timer box to the fascia of the control panel.
There are 2 release clips on the wiring harness block, 1 on top, 1 on the bottom.
Squeeze these and the block slides out.
Reverse the above to assemble.
Done.
