Question about Washing Machines
Check the door switch/switches they are normaly located behind the console at the door latch area. This can be tested with a multimeter in the ohms range (with no power present) put the meter on each contact to the switch and get a friend to toggle the switch it should give an infinite and a low reading on the multimeter.
Check and see if the MCU has been exposed to any water, you can get an understanding of how to get at it by this diagram:
If there is any traces of moisture in or around the MCU use a hairdryer to dry it out for about half an hour and give it another shot.
Hope this helps

First unplug it from the power socket and plug it into a different power socket, you can also try to reset the circuit breaker. If this does not work then you will need to open up your whirlpool washing machine and check the input power coming using a multimeter/ohmmeter. If the power is ok then check for a blown fuse. Please see this link for exploded view of your Whirlpool washing machine.
