LDP6797BD counts down from 4, blink. No error codes
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.
