Symptoms: Touch the power button and it turns on and right back off (chimes and lights come on briefly). May take several cycles to get it to stay on long enough to select laundry type and start.
Also after it finishes the laundry it turns completely off (no lights "off" in the center anymore).

Lid lock was replaced a year ago. Washer is about 5 years old.

Any idea what part going out would cause this?
