I just started having issues with my dishwasher last week.

I came home to it blinking the "Sensing", "Clean", and "Sanitize" lights.

Troubleshooting:
1. Open/close door, press buttons, completely non-responsive - just blinks at me.
2. Kill power. LED display now flashing PF. Open door. PF goes away. Dishwasher completely non-responsive otherwise.
3. Checked for continuity on the door latch, seems to be fine.
4. Replaced "Switch". This is the board with all the buttons. While installing I found that I could run the dishwasher just fine (with the door latch closed). However, there is a ribbon cable leading from the control board to the switch board. If I tightened down the cover for the control board the switch board would stop working (pinching the cable, pulling the connection?). Played with the tightness a bit until it seemed like everything was working ok. However this seems wrong - I don't want steam on these boards!
5. Woke up this morning to the same three lights flashing. No cycle was run, nothing should have changed.

What do I do next?

The way the washer was acting up intermittently seemed like a loose connection or short. I ended up disconnecting all the wires I could find and then plugging them back in again. Seems to have done the trick, no problems over the last 10 days.
