LDP6797BD counts down from 4, blink. No error codes

Hello
I have this LG dishwasher since 1 year now. Once in a while, when to start, i press START, close the door right away and countdown begins and then all lights blinks. 
Sometime, i have to re-open and close the door few times and then it will start.   Looking at the LG app, it sounds like the dishwasher is "pause".
the door has no obstruction and i clean the locking mechanism just in case.
Its very random but becoming very frequent.
Any idea?

    See my comments in thread I opened on this issue.

    Ok. I edited my comments above. Finally, I got A&E service tech to troubleshoot and fix the problem. Side note: LG does not have LG trained technicians in the state of Texas, so it contracts a third-party (A&E) for warranty calls.
    So this tech was a really professional young guy and knew what he was doing. After actual troubleshooting (unlike previous visits by two other A&E techs), he determined that the door's plastic connectors (their role is to determine if a door is closed or not) are occasionally touching the inside top countertop - so that the reason dishwasher works someday and someday not. This is a 'genius' LG design where the installation instructions tell you to attach dishwasher with top mounting flat brackets under the countertop. This makes the unit and thus these electronic door sensing connectors to touch the under the countertop and sense the problem with the door!
    Solution - remove top brackets, connect dishwasher on the sides instead of the top, LOWER THE LEGS a bit so it doesn't really close to under countertop (better even if you forward the whole unit a bit towards you, so the door is a bit out and you can finally see the timer completely) and voila it works! For now... :smile:
