Dishwasher latch was sticking and eventually broke.

Repair is very simple. Make sure to unplug dishwasher or turn off circuit breaker to appliance before performing any work for safety. Open door and remove all Torx head screws holding inside panel to door (place them in a small cup or dish to avoid loss) and tilt up to gain access to switch. Remove connector on each side of old switch (may need to gently pry off with screwdriver), then attach connectors to new switch. Position inside panel back onto door ensuring it is properly seated all around especially near the base of the dishwasher to avoid any leaks. Tighten all screws again and reconnect plug or switch breaker on. Washer is repaired!
