The service manual describes how to check the door lock circuit at both ends. Refer to it and test the circuit. I think you will find that the MCU is faulty. Do not rule out faulty wiring. Ohm out the wiring form both ends to assure you have continuity.

Curious, why did you hit the extra rinse button 4 times? Again, sounds like either something else is malfunctioning or the main board is bad. Does it do anything else like the drain pump come on? Does it try to lock? What does it do during the 15 to 20 seconds before it powers off? Refer to the service manual to test the door lock circuits and run in a diagnostics mode to test components operations.

Open the unit up and check the rollers and felt on the tub. If all is fine the motor has a weak start winding.

Pull and clean the unit with coil cleaner making sure NOT to get the electronics wet. Flush the drain pan under the evaporator coil very well along with the trough that leads through the middle partition ( the middle section between the inside and outside of the unit ) The black stuff is usually mold. An acid based coil cleaner will get most ( usually not all ) of it. Make sure to get cleaner on the blower wheel and rinse as directly as possibly.

Door lock pin alignment could be an issue but so long as the door is closing fully it should not be. Faulty wiring doesn't sound likely since the door switch seems to be sending the signal that the pin is in place. Sounds like a control processor issue. If open up the old switch you can see how it works. Actually pretty simple. The lock solenoid engages a set of contacts that let the board know it's in place. If it switches form not locked to showing locked either it's not really locking or it is but the board isn't processing it correctly. There's always the possibility of a different malfunction in the machine that's not allowing it to move forward with it's program. IE: bad water pump, etc. I've seen Whirlpools do some goofy stuff.
