Whirlpool Duet locked door, drain pump running

I’m unable to provide the model number because the door is locked and won’t open. We’ve had a repair man come out three times and he can’t figure out what the problem is. I’m tired of paying him $100+ each time. Please watch the video below for a description of the problem. You can see and hear what the unit is doing. Thanks!
