I replaced the timer which fixed the problem. Very EASY repair. Unplugged washer from power; removed 4 screws from top of front panel; pulled knobs; popped cap to main knob; removed metal clip that holds main knob (it's spring loaded, so apply slight pressure to avoid flying knob/spring/parts); removed knob-spring-flange; opened front panel to inspect; unscrewed two hex-head machine screws to release timer from panel; removed wire harnesses and installed on new timer; reassembled. The whole process took less than 10 minutes.
